New Disinfectants/Disinfection Byproducts regulations promulgated December 16, 1998 are expected to have significant impacts on existing cold lime softening (CLS) plants in Florida. Because of the high levels of natural organic matter (NOM) typically present in Florida's groundwater and the need to provide softening to reduce hardness to acceptable levels, many utilities are planning the construction of new membrane treatment facilities at tremendous cost. The existing CLS plants represent substantial capital investments that will not be utilized by the membrane technology. This study investigates enhanced softening, and the required modifications to the CLS process to improve NOM removal and reduce disinfection byproducts. Bench and full-scale test results from two south Florida utilities are presented, effectively demonstrating that the CLS process can be adjusted to meet the new regulatory challenges. Full-scale test results for enhanced softening and simultaneous coagulation and softening are presented, using accelators operating at flows from 20 to 40 million gallons per day. Disinfection byproduct data presented includes actual distribution system total organic carbon, trihalomethanes and haloacetic acids. The implications of enhanced CLS residuals management are also discussed. During the full-scale testing, Langlier Index data was collected to insure that the process modifications would produce a stable finished water. Includes 5 references, tables, figures.
