Water Challenges: Power plants require high quality water for the purposes of having smoother processes during operations. Seawater is not good option due to the high salinity in water, which causes scaling and damages in the equipment. For this reason, seawater must be completely treated to produce ultra-pure water in order to be accepted for use in power plants. Pure Aqua’s containerized double pass sea water reverse osmosis systems are designed to provide power plants with much needed water treatment for the production of high-quality water.



Applied Solution: Pure Aqua manufactures containerized double pass seawater reverse osmosis systems for the purposes of providing high quality water from seawater sources to power plants. Our double pass seawater reverse osmosis treatment meets all the requirements of the discharge permit and consists of extracting and eliminating impurities from seawater in two different stages. This allows us to produce ultra-pure water that is needed for certain industries such as in power plants. Our experienced professionals design and build custom-made seawater ro systems that are essential for various types of power plants projects.

    Very neat-looking double ro machine. The design blends well with our new plant. All manuals are provided for simple operations and also has trouble shooting page which is great.
