Water Concern: The power industry includes multiple forms of generating energy. The most common methods that utilize water include boiler feeds, cooling towers, and semiconductors. As heat is applied for energy generation, conductivity and minerals must be filtered out and left as seemingly pure as possible. Due to the nature of these processes, a purified water supply is required to ensure efficient operation, prevent corrosion of equipment, and overall scaling buildup. Pure water is key to an efficient production of energy for any power plant. This customer was supplying their plant with river water containing 6,000 PPM TDS and needed to reduce the conductivity along with the TDS to suit the requirements of their application. They were also looking for a system to produce 1700 m³/day.

Applied Solution: This industrial brackish water treatment plant was recommended to combat high conductivity and TDS levels in river water. The plant includes multiple filtration steps to optimize on the efficiency and production long-term. A pre-treatment process was applied consisting of primarily duplex multimedia filters with a capacity of 1,700 (m³/day) to reduce the silt and suspended solids from the feed water. In addition, a feed/backwash pump was provided to pressurize the water into the RO system. Next, sodium metabisulfite was injected into the feed for chlorine reduction prior to reaching the membranes. Then, a dechlorination system was incorporated along with antiscalant dosing injection to reduce scaling potential on the following filtration systems. The water is then passed through a cartridge filtration unit to remove any suspended solids that may have remained. Finally, the feed is fed into the RO system for purification. A clean in place (CIP) system, which cleans Brackish Water RO Membranes every 18 to 24 months, was also included.
