About the project

Basic and detailed engineering, equipment manufacturing, supervision
of erection, and commissioning were performed during the project
implementation. The water treatment system is designed to operate in
automatic mode.
The temperature parameter is one of the key parameters in the membrane
technology process. It has an impact on the demineralized water quality
and performance of water treatment equipment. Since the temperature
of the feed water coming into the demineralization plant was too high for
ultrafiltration and reverse osmosis membranes, it was cooled.


Heat exchange -> Active carbon -> Ultrafiltration -> Reverse Osmosis

There were used advanced technologies for the demineralization process in this project. Solutions, made
in this project, allow our customer to minimize chemical reagent consumption in comparison to traditional
technologies. Turbidity, suspended solids, iron, organic compounds, and salinity were reduced during the
water treatment process.
