Application of Full Membrane Method and Double Membrane Method in the Deep Treatment of Wastewater in the New Steel Plant
The advanced treatment and reuse of reclaimed water project in Xingang utilizes the treated production wastewater as the source of reclaimed water.The full membrane/double membrane process(old area:ultrafiltration+reverse osmosis+EDI,new area:ultrafiltration+reverse osmosis+ion exchange)is adopted to supply the water users throughout the plant,reducing both sewage discharge and the consumption of fresh water per ton of steel.This article focuses on the application of full mem-brane/double membrane processes in this project.
