ISEP - Continuous Absorption Ion Exchange Systems For Perchlorate/Nitrate Removal

The ion exchange process is generally more suitable as a well site treatment for N03 removal than reverse osmosis or a combination of the two. Ion exchange requires lower capital cost and annual operating costs, has greater reliability, uses less energy, requires no additional well site storage, has higher water recovery, produces more concentrated waste brine and requires fewer automatic and electric controls. It can be operated on demand as required. Such on/oft operation is more detrimental to a reverse osmosis system which operates best on continuous basis.
