Water is an important production factor. In industry water is required that corresponds with the differing needs of respective processes. The spectrum of industrial water ranges from cooling and boiler feed water in power stations and process water for a wide range of industrial uses to ultra pure water for the electronics and pharmaceutical industries.
Process Water
	Industry needs water of different qualities for production purposes. The demands with regard to the standard and purity of the water range from simple, low-quality washing water, to pure boiler-feed water for steam production. The public drinking water network can be used as source of raw water, along with ground- and surface water.
AES offers an extensive portfolio of treatment processes for the securing of the quantitative and qualitative supply of water to industrial companies. Flocculation, sedimentation, filtration, full and partial desalination by softening, reverse osmosis, ion exchange and thermal desalination processes, are combined and implemented according to individual requirements.
The availability and integration of these diverse processes, not only facilitates an optimum response to specific situations, but also water recycling in closed cycles, which conserves resources.
Boiler Feed Water
In various industrial facilities, such as those in the field of power generation or the petrochemical industry, boiler plants are often the key component in the production process. Such plants need top quality water, in order to prevent dangerous scaling.
Boiler feed water is obtained from a wide range of raw water sources. The related treatment processes are tailor-made to match the respective raw water composition and the required boiler feed water quality.
PHOTO For Boiler feed water Treatment
Typical components in AES boiler feed water treatment processes are:
Systems for make-up water supplies, e.g. pre-treatment and demineralisation with silica removal. Systems for condensate treatment, e.g. with filtration, cation exchange and mixed bed filtration. System components for mechanical, thermal and chemical degasification.
Service water
Treated raw water is needed in industrial plants for a diversity of purposes. Around 90% of extracted water is used industrially or for energy generation and distribution.
Service water is necessary for preparatory processing phases or industrial purposes. Typical applications include, e.g. the supply of thermal power stations and petrochemical plants with coolant water, water for fire extinguishing systems and the cleaning of machinery. Service water of an appropriate quality is taken from the corresponding point in the water treatment plant.
During treatment, flocculation, sedimentation, filtration, full and partial desalination by softening, reverse osmosis, ion exchange and thermal desalination processes can be combined or used alternately.
Industrial operations need various water qualities for differing applications, e.g. process water for direct use in production, boiler feed water and treated condensate for boiler plants and service water either as a supplement in cooling towers, or for general purposes.
