BOILERSCASE STUDY CINTAS CLEANING PLANT CALGARY, ALBERTA

Application InformationCintas Cleaning Plant, a commercial laundry company, experienced scale build-up on their steam boiler and heat exchanger. Cleaning both pieces of equipment required the use of harsh and expensive chemicals and additional down time during the annual inspection.The water softener used to protect the boiler was taken off line and a C60 HydroFlow unit was installed on the condensate line to the boiler. Five months after HydroFlow treatment the boiler is free from scale. The HydroFlow unit removed existing scale and left a talc like residue on the tubes, that can be wiped off. The Boiler Inspector asked if the boiler had been chemically cleaned before he had arrived. He also commented that the boiler was unusually clean. The boiler was closed and put back in service.

Inside Plant Boiler

Cintas Cleaning Plant Heat ExchangerCity water is preheated with outgoing wash water , the exchanger is prone to scale and very difficult to clean. A HydroFlow C120 unit was installed and after five months of HydroFlow treatment the inside of the tube and shell exchanger is scale free.Note, what appears to be a mirror polish on the interior of the heat exchanger. Again this unit required no cleaning and was closed up and put back in service.

SynopsisAfter 38 months both the boiler and the heat exchanger have gone through their third annual inspection by ABSA. Both units were in excellent condition and after the inspection they were both closed and put back in service. The ABSA inspector stated that, although he can not recommend HydroFlow to anyone, after looking at the condition of the boiler and heat exchanger he could not see why anyone would not want to use HydroFlow. We did not get an update on cost savings but were told last year that the savings were in excess of $60,000 per year.

In calculating this they took into account the following:• Increased efficiency of the boiler reducing gas consumption• Salt costs reduced• Water savings from not regenerating the softener• Reduced maintenance costs from not having to strip scale from

the boiler or heat exchanger.

COOLING TOWERSTHE DON HARTMAN NORTH EAST SPORTSPLEX – ALBERTA – 2011

The Don Hartman North East Sportsplex is a 64,800 ft2 facility housing two NHL-size ice surfaces (85 ft. x 200 ft.).The cooling tower for the facility was treated with a combination of a water softener, scale and corrosion inhibitors as well as biocides. Although the General Manager was pleased with the results of the chemical treatment on the cooling tower he was interested in reducing the need for chemical treatment. He decided to test a P-120 HydroFlow unit for three months and compare the results with the chemical treatment.

Results of the three month trial period at the Don Hartman North East Sportsplex:When HydroFlow was installed the water softener, scale and corrosion inhibitors were discontinued. The biocides were reduced by 50%. (Pictures on right show same location, taken from a different angle.) 90 days after HydroFlow

Before HydroFlow

After seeing the results of the 90-day trial on the condenser tubes, the General Manager made the following comments: “I can see nothing that tells me that we shouldn’t have this equipment”…and…”I see no evidence that indicates the HydroFlow equipment is not working.”Prior to HydroFlow installation, four directional slots in the 6” pipe, which returned collected water to a remote sump, were constantly scaling up. Upon inspection, five weeks after HydroFlow installation, the General Manager noticed these slots were free from scale for the first time, commenting, “this pipe hasn’t been this clean since I’ve been here.” .

Biocide Reduction by Installing HydroFlow:At the commencement of the HydroFlow trial, biocides were reduced by 50% and six weeks later, Sample #2 was taken (see below). Eight weeks after installation, biocides were reduced an additional 25% from the original level for an overall reduction of 75%. Ten weeks after installation, Sample #3 was taken (see below).All bacteria samples were incubated for 72 hours. The maximum acceptable level for bacteria concentration is 106.Sample #3, with HydroFlow installed for 10 weeks and 75% reduced biocides, shows bacteria levels of 103 - well below acceptable levels.Once the 90-day trial period was over, biocides continue to be used at a 75% reduction from original levels.

Sample #1 July 31, 2011Bacteria level is 104-105

(2 weeks prior to HydroFlow install)

Sample #2 September 29, 2011Bacteria level is 103 biocides reduced 50%

(6 weeks after HydroFlow install)

Sample #3 October 28, 2011Bacteria level is 103 biocides reduced 75%

(10 weeks after HydroFlow install)

Cost Savings:Approximately $4,500/year saved by eliminating the water softener, scale and corrosion inhibitors and reducing biocides by 75%.

Return On Investment (ROI): Based on the savings and the cost of the P-120 unit, the ROI is 53.7%. This means the investment in HydroFlow will yield a return of 53.7% every year.

Payback Period:With an ROI of 53.7% the cost of the P-120 unit is fully paid back in just over 22 months.

Additional Activities: Impressed with the trial results, the General Manager is inquiring about HydroFlow units for the mixing valves which scale up and need cleaning every 6 months.Environmental Impact of HydroFlow: In addition to substantial cost savings, the Don Hartman North East Sportsplex has reduced its impact on the environment by eliminating the use of a chemical water softener, scale and corrosion inhibitors, and reducing biocides by 75%

HUMIDIFIERS

SALVATION ARMY

Product Recommendation S38Great results were achieves after installing the S38 on the Salvation Army Engineered Air Steam HumidifierThe HydroFlow EffectThe HydroFlow signal keeps the ions in suspension. Without our protection the ions will precipitate out of the water to form hard lime scale.Any precipitate that forms in these extreme conditions after the water has been treated by HydroFlow would be of a soft nature which can be easily transported away by means of an automatic (if available) or manual blow down regime.In the event the equipment is not equipped with any blow down facilitation you will find that periodic cleaning would be much easier.

operation.

Equipment LongevityIt’s quite commonly known that slightly hard water is preferred for use on equipment that includes any heating cycle as it generally not corrosive.This is the reason why many manufacturers of steam generators, ovens and humidifiers will not warrant equipment that is supplied with softened water as it will reduce the life and can be damaging to the equipment.Through the use of HydroFlow technology we can now have an ideal scenario where we can accomplish great results.

Install LocationWith these applications it is imperative to know and understand the equipment being treated so that the HydroFlow can be applied in the optimum location, this is due to the fact that this type of equipment predominantly uses either Solenoid or float ball valves in the process, being on the wrong side of a valve will make all the difference. Please ensure you consult with your dealer for install location assistance.

HEAT EXCHANGERSTRICO CENTRE FITNESS & WELLNESS FACILITY

Trico Centre uses plate & frame heaters to heat all of their domestic hot water for the recreation centre. They had these installed in 2009 and they worked really well for the building for the first 8 months and then they found that they were running out of hot water and pressures where dropping.

Upon trouble shooting they found both heat exchangers plugged with scale and were forced to take the exchangers apart and clean. After cleaning they found their water pressure and supply returned to normal.

From 2009 until 2012 they were forced to clean these units every 8 to 10 months, the biggest issue was the costs as a set of seals for one unit is around $2200.00 per cleaning.

After doing some research they found HydroFlow and together they chose a course of action. The operations manager was skeptical and felt believing was seeing. A HydroFlow unit was installed on the main line to the plate and frames units, about 3 months before their annual cleaning. They continued to monitor these and as a result pressures actually increased about 3 PSI and were showing no signs of any issues.

In 2013 they decided to shut down 1 plate and frame and open it up. What they found was all of the plates inside looked like new and the only scale that was found anywhere was about 1/16 of a cup at the inlet flange.

Conclusion: It has convinced the operations manager that these units do work, and he would not hesitate in purchasing HydroFlow again for this application.

Inspection Report After HydroFlow Installation

At a six month inspection, the hot water tank flues (A) were scale free but covered by light talc (an expected result of breakdown of existing limescale). The talc easily wiped off with a cloth (B and C). Pictures A and B show the bottom of the tank covered with a thin layer of loose scale (~one-sixteenth of an inch after 6 months without flushing out or cleaning – substantially reduced from maintenance reports of one-inch of scale every 6 weeks). After vacuuming, the bottom of the tank just above the access opening is scale free (C). One sees a thin layer of scale adhered to the bottom of the tank, which is expected to breakdown over time and wash away. During inspection, the tank was flushed twice from the top. As no additional scale flushed out, one may assume that the upper regions of the tank are scale free.

DOMESTIC HOT WATER TANKSRED WOOD INN & SUITESALBERTA – 2011

Opened December 2008, this award winning 92-suite hotel waged an uphill battle against limescale build up. Even though two 80-gallon hot water tanks were drained and cleaned every 6 weeks – at

considerable cost to management – the tanks continued to be so clogged with scale that a high-pressure air hose had to be used to unblock the drains before cleaning and vacuuming out the tanks. Additionally, three guest suites in the hotel could not be rented out due to the significant amounts of limescale coming out of bathroom taps.Looking for a maintenance-free, environmentally safe alternative to salt based water softeners, the owner purchased a HydroFlow C-100 commercial unit, and attached it to the cold-water feed to the hot water tanks. One month after HydroFlow installation, the owner reported that the drains of the hot water tanks were not clogged with limescale. A high-pressure hose wasn’t needed to unblock the drains; water flowed smoothly from the drain tap. Draining and cleaning the tanks was postponed, saving management substantial time and money. Three months after HydroFlow installation, water from the hot water tanks flowed freely, clear of scale, and tanks didn’t require draining or cleaning. Four months after installation, the three suites no longer had scale in the bathrooms and are rented out regularly to guests. Six months after installation, the tanks are opened and inspected; vertical flues are scale free, indicating that HydroFlow is preventing new limescale from forming. Existing scale at bottom of tanks is substantially reduced.

Tank Cleaning Prior to HydroFlow

Prior to installing HydroFlow, maintenance staff reported tank cleaning required EVERY 6 WEEKS, removing ~70% of scale in a laborious full-day process. Cleaning sessions involved repeated tank flushing to remove scale from the upper region of the tanks, and attempts to vacuum up limescale. Vertical flue stacks remained encrusted with scale after each cleaning. Maintenance staff estimated that about one-third of the amount of scale shown in the jar (above) remained in the tanks after each cleaning, causing substantial reduction in tank efficiency and increased energy consumption. Approximately one inch of scale built up every six weeks and scale continued to come out of the taps in three suites, making the suites unrentable.

Tank Cleaning After HydroFlowNO TANK CLEANING was required in the 6 months after HydroFlow installation – saving staff a full day of maintenance every six weeks and hotel management substantial financial output. Four months after installation, limescale in hotel suite bathrooms disappeared and rooms were available for guest rentals.

Impact of HydroFlow on Red Wood Inn and SuitesPayback period for HydroFlow

Less than one month of revenue generated from the three hotel suites (formerly unavailable to guests) was sufficient to payback the initial HydroFlow investment. This does not take into consideration the money saved on energy savings and tank cleanings. Additional savings in manpower hours and frustration-reduction to owner and staff have been immeasurable!

Greatly extending maintenance intervals and equipment longevity means more profits.

It just makes sense.

Luxury Comes at a CostMost hotel and Leisure locations these days offer their clients the benefits of steam rooms to enhance the client’s experience.

The underlying problem with this equipment, is that the steam generators are plagued with problems when operated with hard water; why not just use a softener, using a softener on this kind of equipment creates a corrosive problem due to the high temperatures used. (So eliminating one problem just created another)

HydroFlow will address these problems by greatly reducing maintenance time and extending the intervals.

SWIMMING POOLSLYLE HALLMAN SWIMMING POOL ONTARIO – 2011

The City of Kitchener, Ontario, owns and operates this 25 metre indoor pool at Lyle Hallman. Because 300 – 500 swimmers use it daily, this pool requires significant amounts of chemicals to maintain.An AquaKlear HydroFlow P-160 unit was installed and monitored from July 12 – August 15, 2011. Chlorine pump readings were recorded daily.During the monitoring period, a low count of chloramines was maintained despite discontinuation of chlorine shock treatments. Daily chlorine readings showed a 51% decrease in chlorine use. Employees at the pool noticed an improvement in water clarity, as well as a significant reduction of chlorine smell.

Gallons of Chlorine

Chlorine Usage - reduced by 51%

HydroFlow AquaKlear

Cost savings:Chlorine was reduced by 51% during the monitoring period resulting in a savings of over $3,500 annually. By discontinuing chlorine shock, there was an additional annual cost savings of over $4,800.Total cost savings: $8,300 annually.Return On Investment (ROI): Based on an annual cost savings of $8,300 and the price of an AquaKlear P-160 unit, the ROI is 59.4%. That means an investment in HydroFlow will yield a return of 59.4% every year.Payback Period: With an ROI of 59.4%, the cost of the P-160 unit is fully paid back in just over 20 months.Additional Benefits: • Water was consistently clearer during the

HydroFlow trial period as a result of particulates being flocculated without chemicals – increasing filtration abilities

• Shock was not required to maintain low count of chloramines

• Algae, bacteria, and other potential parasites get treated as they pass through the ferrite ring of the P-160 unit – greatly reducing extra chlorine needs

• Air quality improves as a result of low chloramine count

• Duration and frequency of backwash can be reduced, within government guidelines

• Lime scale is prevented – keeping heating unit(s) running at optimum performance

Environmental Impact of HydroFlow: In addition to substantial annual cost savings, the City of Kitchener reduces its impact on the environment with a 51% reduction of chlorine use and the 100% elimination of chlorine shock. Water consumption is decreased through reduction of frequency and duration of backwash. A decrease of energy consumption to heat replacement water is also realized.

Impact of HydroFlow on Lyle Hallman Swimming Pool

YMCAONTARIO – 2011

At this 50,000 gallon YMCA indoor swimming pool in Ontario, staff works diligently year-round to ensure guests have an enjoyable swimming experience.Substantial amounts of chemicals are used to maintain optimum pool conditions, and effectively stay within the target range of 0 – 1.0 ppm of chloramines.Two different shock treatments are used to sanitize the pool costing over $5400 annually: 425 kg of SM Brite (Potassium ion phosphate) and 60 litres of Hydroxian (liquid oxidizer).The pool operator had ongoing concerns about chloramine count – directly affecting water and air quality – and possibilities of Cryptosporidium parasite being brought into the water by swimmers. Parasite prevention treatments involve super chlorinating the pool over a 48 hour period.

AquaKlear P-100 unit installed to reduce chemicals – effects monitored over 30 days • chloramines averaged 0.46 ppm • no shock added to pool during

monitoring period • over 50% reduction in chemical use

YMCA employees noted • visible difference in water clarity in

first week • noticeable reduction of algae

Jan Feb July with P100

Combined Chlorine Reading

With P-100: shock treatments were discontinued in July

Cost savings: Shock treatments are discontinued resulting in an annual cost savings of $5,445. (Cost savings for additional chlorine use are unavailable).

Return On Investment (ROI): With an annual cost savings of $5,445, the ROI is 77.9%. This means an investment in HydroFlow yields a return on investment of 77.9% every year. (ROI increases when the cost savings for chlorinating the pool are included.)

Payback Period: With an ROI of 77.9%, the cost of the P-100 unit is fully paid back in just over 15 months. (Payback period decreases when the cost savings of chlorinating the pool are included in the ROI.)Additional Benefits:• P-100 ferrite ring treats algae, bacteria and other

potential parasites• Shock is not required to maintain low chloramines

count

• Water clarity improves as particulates flocculate without chemicals - improving filtration

• More than 50% reduction of chemicals to maintain this pool

• Air quality improves with low chloramines count

• Duration & frequency of backwash reduced within government guidelines

• Lime scale prevented – ensuring heating units run optimally

Environmental impact of HydroFlow:

In addition to substantial annual cost savings by eliminating shock, the YMCA further reduces its impact on the environment with a greater than 50% reduction of total chemical use. Water consumption is decreased through reduction of frequency and duration of backwash. Decrease of energy consumption to heat replacement water is also realized.

AGRICULTURAL IRRIGATION

APPLE ORCHARD

Customer: The grower has been growing, packing, and shipping premium tree fruit products since the 1920’s, with orchard locations throughout the prime growing regions of Eastern Washington.

Application: Scale accumulation on apples.

Device: Custom HydroFlow 12” Water Conditioner.

Installation date: July 17, 2013

Evaluation date: September 17, 2013

Background:The Orchard in the Yakima Valley, Washington, incorporates overhead sprayers for temperature control and protection from sun damage.

Problem area:Even though acid is added to the sprayed water, apples still gather hard scale stains. The scale staining reduces the grade of the apples. In an average growing season, only 50% of the apples receive the highest grade rating.

Proposed solution:Install a Custom HydroFlow 12” I Range on the pipe which supplies water to the Orchard.

Results:Scale deposits accumulate as fine powder which is very easy to remove. Over 90% of the apples are expected to receive the highest grade rating once processed. Note: The apples were picked at the end of 2013, placed in cold storage and are expected to be processed, packed and shipped during the first quarter of 2014.

Additional Observations:Two weeks after the installation of the HydroFlow water conditioner, the pond’s water became much clearer and the floating algae blooms reduced significantly. In addition, snails that used to clog the filters are no longer present.

Quote from customer:Orchard Manager: “The pond has never been this clear and the white powder washes right off the apples. The benefits of HydroFlow should have a very positive impact on our profits this season. Initial processing results are the best I’ve ever seen.”

HistoryPrevious experiments with corn using drip irrigation and magnetically stimulated water yielded very positive results with increased yields of up to 30% and as much as 50% decreased water and fertilizer. Other observed findings also included larger and healthier plants with a more developed root systems. The current experiment used a new Zimatic 9000 circle with lake water irrigation. All delivery equipment was new; pipes, filters, and pump system with the latest Fieldnet computer control system.

Testing ProcedureThe crop circle was divided into four plots.

1. Control with plain lake water.

2. HydroFlow stimulated lake water.

3. HydroFlow and Magnetically stimulated lake water.

4. Magnetically stimulated lake water.

All four plots were matched; water and fertilizer was equally applied to all test areas. There were no significant soil differences. There were minor elevation differences. All were planted with the same Pioneer 36V51 corn on the same day and at the same density. The corn was a 102 day variety planted in April and harvested during the 3rd week of December with 17.4% moisture content.

Results

Discussion1. Both plots with HydroFlow obtained better yield than the control

plot, and in addition, the HydroFlow plots had better color and roots.

2. The magnetically stimulated plot had slightly less yield than the control plot but still showed good growth, color and slightly better root system than the control.

3. The corn was given water and fertilizer by a trained farm manager but I feel both were introduced in excess. The optimum amount was probably greater than required which may have had adverse effects.

4. It is interesting to note that a similar nearby field of Pioneer 36V51 corn that was fertilized in the same manner but used siphon tube water delivery, yielded only 5 tons/acre or 20% less than our four experimental plots.

CORN CROP

Plot Colour Avg. Plant Height Roots Yield

Control Green 108.5” Normal+ 5.97 tons/acre

HydroFlow Lush green 120.0” Normal+++ 6.35 tons/acre

HydroFlow & Mag Lush green 132.9” Normal++ 6.16 tons/acre

Mag Lush green 121.4” Normal+ 5.94 tons/acre

Future experimentsDr. Stuart O’Byrne1. In the past, I conducted drip irrigation experiments which allowed for more continuous water and fertilizer utilization while using lessened amounts of both. Historically, these experiments yielded better results.

2. It is clear that HydroFlow had a positive effect on the corn which merits further testing that may include the combination of drip irrigation and a more sophisticated monitoring and control system.

There are several problems that commonly occur with reverse osmosis. First is that the membranes have a tendency to scale up. As the water is pushed through the membrane, the concentration in the water near the membrane increases - we can think of this as an increase in the hardness of the water. This increase in concentration means that the water becomes supersaturated and therefore starts to form scale on the membrane.

Another problem is that bacteria and algae can grow on the membrane. The scale that forms there can make bacterial growth problems worse as it gives the bacteria a place to hide! Both of these problems lead to blocking of the membrane. As can be imagined, semi-permeable membranes are rather prone to blocking, either by scale or by fouling from bacteria and algae. Blocking the membrane will make it even harder to force water through it, and therefore lead to a further decrease in the flow and the amount of fresh water produced.

Prevention of Scale

By treating the water coming into the system, we can create clusters which form crystals when they hit the concentration layer. These crystals will then be washed away by the cross flow.

Prevention of Biofouling

By treating the incoming water, we can prevent buildup of biofouling on the membrane. Note that we cannot clean up a membrane that has been already fouled with bacteria.

Reduction of Osmotic Pressure

Another advantage that HydroFlow has is to reduce the osmotic pressure and thereby increase the flow rate. It does this by disrupting the concentration layer. Basically, when limescale crystals are formed in the concentration layer, their motion as they are moved in the cross-flow will disturb the concentration layer, essentially stirring it up. This will reduce the concentration in the water next to the membrane and hence increase the flow rate.
