CHALLENGES FACING ENERGY PRODUCERS
OPTIMISE YOUR WATER MANAGEMENT TO ACHIEVE
YOUR ENERGY PRODUCTION OBJECTIVES
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 reservoir
Cooling 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" circuit
Micromolecular 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 system
Macromolecular purification.•
Micro­biological 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.

PROMOTING SUSTAINABLE
DEVELOPMENT
Ondeo 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

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.

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
