INDUSTRIAL
WATER
TREATMENT
In industrial plants, water corresponds to a significant factor in every process which ranges from cooling water, boiler feed water to pulp & paper industries as well as process water for the electronics and pharmaceutical industries. In various industrial facilities, such as those in the field of power generation or the petrochemical industries, boiler plants are often the key component in the production process. Such plants need top quality water, in order to prevent dangerous scaling. We can provide proper solution as per the process requirements. Shafab has a valuable portfolio of treatment processes including conventional processes to high-performance systems (e.g. membrane processes). Our target is to add the features of reliability and least operating maintenance requirements for our proposed solutions. Major industrial water treatment plants have been described hereunder:
Boiler Feed water is obtained from a wide range of raw water sources. The treatment processes shall corelate the corresponding raw water composition to the
required boiler feed water quality through the following solution and systems:
- Make-up water supplies, e.g. pre-treatment and demineralization and silica removal (thermal or RO desalination and ion exchange)
- Condensate treatment, e.g. with filtration, anion- cation exchange and mixed bed filtration and degasification
- Mechanical, thermal and chemical degasification.

A condensate polisher is a package used to filter water condensed from steam generated from the steam cycle. It is frequently filled with polymer resins which are used to remove or exchange ions so that the purity of the condensate is maintained at of the distilled water. It prevents premature chemical failure and deposition within the power cycle resulting in loss of unit efficiency and possible mechanical damage to the key generating equipment.
Condensate polishers are important in systems using the boiling and condensing of water to transport or transform thermal energy as it removes dissolved (i.e. silica oxides) and suspended matter (ex. iron oxide particulates from corrosion, also called ‘crud’), as well as other contaminants which can cause corrosion and maintenance issues.
Condensate polishing typically involves ion exchange technology for the removal of trace dissolved minerals and suspended matter.
During the process of steam generation in power plants, the steam ccools down and condensate is formed. Then it is collected and used as boiler feed water. Prior to re-use, the condensate must be purified or “polished”, to remove impurities (predominantly silica oxides and sodium) which can potentially damages the downstream facilities. The CPP process is normally being implemented through the following methods:
- High pressure Mixed bed Exchanger
- Low Pressure Mixed Bed Exchanger External Regeneration Mixed Bed
- Precoate Technology

The condensate deoiling package is used to remove potential hydrocarbon traces from the steam condensates. The clean condensates are utilized to feed deaerators in production of boiler feed water (BFW). Coalescing filter and activated carbon filters are being employed to meet the purpose. Coalescing is one of the separation techniques applied worldwide for liquid-liquid and liquid-gas separation processes.
This technique involves coalescing of small particles or droplets into larger ones by means of barrier or electrical energy. It is one of the most cost effective methods practiced nowadays as compared to salt driers, settlers or thermal / vacuum separators.

Service water is necessary for preparatory processing stages and/or industrial purposes. Typical applications include, e.g. cooling water supply for thermal power stations and petrochemical plants water for fire-fighting systems and the machinery cleaning. During the treatment process, flocculation, sedimentation, filtration, membrane filtration, full and partial desalination by softening, reverse osmosis, ion exchange and thermal desalination will be combined or employed alternately. Eventually, the service water of pre-defined quality will be the product of taken from the corresponding point in the water treatment plant.
