Abstract
The reduction of disinfection by-product (DBP) precursors by nanofiltration was investigated in Florida at both a groundwater site and a surface water site. Separate studies, involving pilot plant operations, were conducted for one year at each site. The principal research tasks at each site were membrane selection, selection of an appropriate pretreatment process and operation of the membrane pilot plant. At the groundwater site (Daytona Beach, FL), conventional pretreatment (scaling control and pre-filtration) was required to control nanofilter fouling. Over one year of pilot plant operation, the average DBP Formation Potential (DBPFP) in the system permeate was 20 micrograms/L as Cl(-), representing a 96 percent reduction in the DBPFP of the raw water. At the surface water site (Melbourne, FL), alum coagulation, GAC filtration and microfiltration were all used as pretreatment options for nanofiltration. Over one year of pilot plant operation, the average DBPFP in the system permeate of the alum coagulation/nanofiltration combination was 22 micrograms/L as Cl(-), representing a 98 percent reduction in the DBPFP of the raw water. Using the pilot plant data, capital and operation and maintenance costs were developed to construct a 10 MGD nanofiltration plant at both the groundwater and surface water sites.
