AWWA ACE65410

This powerpoint presentation begins by providing history and background information of four water utilities in the Michigan towns of Chelsea, Davison,Grand Blanc, andSaline. The drivers for membranetechnology for softening included:application of new state-of-the-arttechnology for multi-contaminantremoval;small, modular footprint would saveon building costs;full automation allowed reducedstaffing requirements; and,no lime sludge from conventionallime softening process. Project driving forces included:regulatory requirements achievablevia membrane separation technology;capital costs were essential forproject feasibility for smallermunicipal utilities; and,"Turnkey Solution" was selected tomeet initial budget and scheduleneeds in lieu of traditional"Engineered Solution" approach. Separate costs for membrane softening and the operation and maintenance of membrane softening are given, along with design criteria, membrane treatment system schematic, raw water supply, chemical pretreatment, physical pretreatment, membrane feed pumps, membrane treatment, post-treatment, concentrate disposal methods, construction, start-up and testing, operation and maintenance, and recommended improvements. Includes figures.
