Models 4DAXX00. Main Features:

Antiscalant doser instead of a water softener with salt.

Antiscalant automatic mixture preparation.

Backwash with demineralised water instead of feeding water. Advantages due to the use of antiscalant:

Ecological: No brine from the water softner regeneration Logistics and easy use: no need to stack salt bags and simplicity Cheaper: antiscalant is cheaper than salt consumption Expansion of the action capacity: wide espectrum

Balance in the ratio production/surface & reject/surface of the membrane compared with the old existing equipments.



Models 4DAXX00. Main Features: Quality of components:

• Programmable PLC Siemens S7-200• Centrífugal Pump Grundfos• Metering Pump Prominent• Stainless steel frame quality AISI-304• Piping of High salinity range in stainless steel AISI-316• Toray membranes: TMG10 (Low salinity), TM710 (High salinity)

Production can be upgraded just by adding membranes to the existing equipment (no need to buy a full new system).

Suitable cabinet assembly

Wide range of pre-treatments available:



Just like a car, the models 4DA have two types of alarms to inform us about any possible failure and its seriuosness.

Models 4DAXX00. Example of anomaly


Buzzer included to alert the customer about

the failures.

• The equipment must recognize the adverse conditions to assure a long operational life.

• The demineralisers are equipments overlooked by the customer (is a non productive equipment) and usually there is not a preventive maintenance of these installations.

• The equipment will stop only if there is an imminent risk to its operating life, avoiding irreversible and expensive damages.

• The customer must be informed of any anomaly (critical or not) without decreasing the business.

Maintenance of Demineralisers 4DAXXXX

1.- Daily maintenance

To check the level of chemical product.

2.- Every week

To check and to take note of pressures and flows.

3.- Every 3 months

To check the condition of the filters (FS1 & FS2), if necessary they should be changed.

4.- Every 6 months

To clean the small tanks of anti-scalant and backwash water.



Water softener 2x100 litresSalt Consumption:

– Daily need of water: 21 m3 at 70 ºHF (39,2ºHD).

– Necessary regeneration of the water softener every 9 m3

– Number of regenerations per day: (21m3/day) / (9m3/ regeneration) = 2.3 regenerations /day

– Consumption of salt per litre of resin in every regeneration: 0,2 kg/Litres of resin

– Consumption of salt in every regeneration: 0,2 kg/Litre of resin x 100 Litres of resin = 20 kg of salt per regeneration

– Salt consumption per day: 2.3 regenerations / day x 20 kg of salt/regeneration = 46 kg/day

– Salt consumption in the same period of time (124 days): 46 kg/day x 124 days = 5. 704 kg = 228 sacks of 25 kg

Antiscalant dosageConsumption of antiscalant product:

– Daily need of water: 21 m3 at 70 ºHF (39,2ºHD).

– “High” dosage of product: 5 mg/L = 5 g/m3 – Daily product consumption: 21m3 x 5 g/m3 =

105 g/day = 0.105 kg/day– 1 carafe 10 L = 13 kg– So 1 carafe of 10 litres of antiscalant will

last: 13 kg / 0.105 kg/day = 124 days

Example of calculation of Antiscalant vs Water Softener



Conclusion: In 124 days of use:

5.704 Kg of salt =

1 bottle of 10 L (13 Kg)

Make yourself your calculations:

Price/kg Salt x 5.700 kg salt = Euros spent on salt versus

PVP 10 L Antiscalant carafe = 189 ,00 Eur
