Full Description

The first brackish water desalination water treatment plant in Massachusetts will be constructed along the TauntonRiver in Dighton, Massachusetts. The source water is seasonally brackish and salt water intrusion at the proposedintake location normally takes place during the period of July through November. The source water is high innatural organic matter (NOM) and color, with wide variations in temperature and salinity. Thus, the full-scaleprocess being considered must not only be adequate in providing proper pretreatment for the reverse osmosissystem, but must also be able to provide full treatment when the reverse osmosis system is not required forremoval of total dissolved solids. Specifically, the pretreatment process must be effective in removing NOM,color, turbidity and particles for compliance with the Stage 1 90 % removal of apparent color. The use of ferric chloride as primary coagulant proved mosteffective for NOM removal. Includes 9 references, tables, figures.
