Potential Solutions: Coagulation injection.-This project will include a pretreatment system to reduce the DBP formation potential. A Rapid Small-Scale Colum Test (RSSCT) will be performed to evaulate the variablility of the raw water and determine the best long term solution. Most probable treatment options will be enhanced coagulation and GAC in addition to the current membrane filtration.-This project will include a pretreatment system to reduce the DBP formation potential.
