Auditing, engineering and expertise to identify the most appropriate resource(s). Choose, design and employ the best technologies for feeding the low and high temperature reservoirs.

Operation of your cooling towers and water production facilities to guarantee peak performance levels. Technical assistance, maintenance and supply of water conditioning products as part of our specialised services: CoolSure, UpSure and UpCare drawing on the latest technologies, such as ATP-metry*.

To cope with major changes in legislation, climate and population, operators of thermal power plants (coal, lignite, fuel oil, gas, biomass, nuclear and solar) must meet two objectives:

Maintain or improve the competitive advantage of their •production plant. One way is by controlling water quality at different points in the application.

Conform to increasing environmental and health constraints. •

Whether used to feed the low or high temperature reservoirs, producing water to a high quality standard or in high quantities (depending on requirements) has a strong impact on any facility's energy efficiency.The solution is to choose and/or optimise the water treatment process in response to available water resources and the potential environmental impact within the larger picture of sustainable development.

Technical constraints

Low temperature reservoirCooling system

Corrosion and scale in the condenser, clogged packing in the cooling towers, meeting water demand, suspended solids, total alkalinity, total hardness, phenolphthalein alkalinity, controlling legionella.

High temperature reservoir "Steam" circuit

Availability of water, conductivity, silica and Total Organic Carbon (TOC) content.

Installation and equipment providing access to all the technologies used by energy utilities for:

"Steam" circuitMicromolecular and ionic purification of water (demineralisation).•

Elimination of dissolved oxygen and dissolved or latent carbon dioxide.•

Condensate treatment.•

Potential recovery of boiler blowdown water for recycling (control over ionic •concentration and reduced heat loss).

Solution for treating water used in smoke and dust treatment lines (especially •in sulphurous form) in the case of fossil fuel power plants.

Cooling systemMacromolecular purification.•

Micro biological purification of water.•

Circuit blowdown treatment to comply with •regulatory and sanitary constraints (saline and AOX discharges, microbiological quality, etc.).

*molecular biology technique to measure levels of microorganisms in water.

BenefitsGlobal management of your installations covering your entire •range of operations with a single point of contact.

Guarantee of leveraging recognised technological and operational •expertise in managing energy production facilities, delivering service continuity and continuous water quality.

Health risk control.•

Reduction in scale formation, corrosion and clogging in your •networks and installations, guaranteeing their long term reliability and efficiency.

Optimisation of your existing facilities or deployment of the most •suitable treatment systems for your requirements to reduce water usage (reuse, recycling), thereby future-proofing your installations and curbing operating costs.

Access to our expertise in water treatment throughout the •entire chain, capitalising on the latest technological innovations driven by SUEZ ENVIRONNEMENT's 75-year plus track record in research.

ProMotinG sustainaBLe deVeLoPMentOndeo Industrial Solutions supports industry as part of its move towards sustainable development by offering innovative, leading-edge solutions covering the following three key areas:

Rational management of the water resource:• reduced use of water and chemicals, optimisation of processes encouraging energy recovery, and solutions for reusing and recycling water.

Minimised impact on the ecosystem: • compliant installations, reduced use of chemicals, increased recycling, and limited discharges both in terms of volume and flow.

Protection and development of human resources: • ergonomic installations, minimal sound pollution, strict health, quality and safety policy.

Therefore, you can take real steps towards a sustainable development, while focusing on your core business – producing energy.

End-to-end operation and maintenance for an effective start to production, with steam generation of 1 200 tons/hour and a streamlined consumption capacity, resulting in a substantial reduction in the ratio of waste used for each ton of team produced.

"Thanks to you, our power plant started on schedule. We are certain of the

facility's reliability and we have ramped up steam and electricity production with

no extra water usage!"

United Kingdom, gas power plant of a "major" oil company

Construction of a treatment plant to produce 545 m³/h of demineralised water from surface water via an innovative treatment process combining double pass reverse osmosis with ultrafiltration.

"Ondeo IS suggested a new technology for our power plant, and we are happy to have

agreed to work in partnership with them in building a plant that we both consider

to set the gold standard!"

Italy, gas power plant

Flexible solution for producing 168 m³/h of demineralised water from sea water or surface water, where the type of water can be changed in two hours, ensuring a fully standalone water production system and streamlined operating costs.

"We enjoy a good relationship with Ondeo IS, and any problem that may occasionally occur on site can

be resolved promptly and efficiently."

Spain, gas power plant

France, district heating company

Installation in a highly size-restricted city location (180 m²) of a plant producing 300 m³/h of reverse osmosis water, offering the customer a flexible space solution.At two other power plants equiped with co-gene-ration systems (2 × 125 MW electricity), Ondeo IS has also provided a fast demineralised water supply for the recovery boilers (600 m³/h for both sites).

"Ondeo IS did the impossible: producing large volumes of demineralised water in a location with a small footprint."

Construction of a new facility for treating ammonia-rich condensate through high-pressure reverse osmosis, respecting quality accreditations.

"Building a water demineralisation nuclear site calls for strict compliance with technical

specifications and procedures. Ondeo IS masters these and we really appreciated their

support on this contract."
