One Mgd Ion Exchange Plant for Removal of Nitrate from Well Water

摘要

A full scale 1 mgd demonstration plant, using ion exchange, for removal of nitrate from well water was built at McFarland, California. The plant has been performing satisfactorily in the semi-automatic mode since October 1983. Full automation of the plant was completed in June 1984. State of California requirements of reducing nitrate levels below 10 mg/L NO3-N and eliminating brine from the product water have been met. Total costs for the plant, including capital and operation and maintenance were 24.2 cents/1000 gal. Research is continuing at McFarland on nitrate selective resins, regenerant re-use, monitoring and brine disposal, in an effort to further improve the process and reduce costs.
