The Right UF For RO: Power Plant Chooses Koch Membranes For Ultrafiltration Pretreatment In Reverse Osmosis Desalination

To produce electricity, power plants require large volumes of high quality water for boiler make-up and for cooling. However, in most locations in China, where water resources are scarce, no surplus water is available and the government will not allow power plants to place additional demands on the already scarce water supply.

New power plants must either find alternative sources of water, such as seawater or wastewater to gain government approval, or they must pay very high fees for surface water or ground water.

At the new electrical power plant in the Liaoning Province coastal city of Zhuanghe, seawater was a natural choice to supply the water needed to run the facility. The plant supports the region’s thriving economy, which is driven in large part by the governing sub-provincial city of Dalian, a prosperous industrial center with the third largest port in China and the country’s northernmost ice-free seaport.
