Optimizing RO Recovery Using Cyclic Ion Exchange "free regenerant" Technology
Cyclic Ion exchange (CIX) can be used on RO concentrates with brine conentrations as low as 2%. When combining antiscalant and CIX RO reject can be increase to 90%....
Using Cyclic Ion Exchange Softening with Antiscalant Dosing to Increase RO Recovery
This paper examines the synergies afforded by using cyclic softening plus antiscalant to optimize RO recovery rates when treating brackish and semi?brackish feed waters....
Synergistic Use of Ion Exchange and RO Technologies in Multi-Contaminant Removal Applications in Drinking Water
Paper explored the use of cyclic ion exchange to reduce reverse osmosis (RO) concentrate volumes produced in the treatment process. Report suggests that the ion exchange softening of the RO feed water allows for higher recovery rates by minimizing the potential for membrane scaling. Potential reductions in concentrate volume of 5-10% are noted....
