A successful start-up of a novel ion exchange color and disinfection byproduct (DBP) precursor removal treatment system was completed in 2000. This treatment system was used in conjunction with the existing 16 MGD lime softening treatment units and filters for potable water treatment. A side stream is removed from the existing lime softening treated water and passed through a 6 MGD ion exchange treatment unit to remove Total Organic Carbon (TOC) and color, thereby reducing DBP formation potential in the finished water. The existing lime softening equipment and the existing wells were in good condition and produced acceptable water but higher quality water was desired. The City compared various options such as anion exchange, membrane softening, reverse osmosis(using a saline water source) and ozone. It was determined that the most cost effective method for improving the water quality was the anion exchange system. It was also determined that this system was very efficient with respect to generating wastewater flows. Less than 1% of the water treated is sent to waste disposal verses approximately 15% for a comparable membrane treatment system. Essentially all the color is stripped from this side stream. Removal of these precursors reduced total trihalomethane (TTHM) formation during disinfection with chloramines and allows the plant to meet current and most likely future US Environmental Protection Agency DBP regulations at a very low installed capital and operations and maintenance cost, significantly lower than a membrane treatment system.
