16x60 Mesh macropourous perchlorate-specific, extended run resin regenerable by the ORNL process

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.

Evolving ion exchange technologies for perchlorate removal from drinking water

CalRes 2103 is an advanced macroporous, anion ion exchange resin with excellent capacity for perchlorate and more than three times the selectivity for nitrate ions when compared to the best available products. It is tested and certified by the Water Quality Association under ANSI/NSF 61. CalRes 2103 has a new chemistry that prevents nitrate spiking in the effluent water. CalRes 2103 is characterized by a high degree of porosity, very stable structure and limited reversible swelling, which results in a kinetically superior and durable resin.
