Back to the Future: Evaluation of NF Membranes for a Return to Free Chlorine

The City of Corpus Christi is performing nanofiltration (NF) pilot testing as a way of evaluating the feasibility of returning to free chlorine disinfection from the current usage of chloramine. The NF pilot will verify performance of the treatment process to remove organics and DBP formation potential. Utilities that are currently using free chlorine or considering the switch from chloramines to free chlorine as a distribution system disinfectant will gain knowledge regarding the usage of nanofiltration to lower the risk of Disinfection Byproducts (DBPs). Those utilities using chloramines will also learn about the benefits and challenges of implementation of a NF pilot system for the treatment of surface water organics.
