    Abstract:
    This publication identifies lake eutrophication, its biochemical process, causes, effects, prevention, lake restoration, available technologies (electroflotation, dissolved air flotation and filtration), etc. Two continuous pilot plant studies were conducted: (a) treatment of septic tank effluent along lake shoreline by electroflotation-filtration (EFF) and drainfield for lake pollution prevention; and (b) treatment of Stockbridge Bowl water by EFF for lake restoration. The new technologies were jointly developed by the Lenox Institute of Water Technology (LIWT) and Krofta Engineering Corporation (KEC). For lake pollution prevention, a septic tank effluent was successfully treated to meet the NPDES effluent discharge permit requirements. For lake restoration, Stockbridge Bowl water was successfully treated in terms of high % removal of phosphate-P (100%), TSS (100%), COD (71%), color (95%), turbidity (90%), aluminum (58%), and algae or particle counts (99.7%), etc. The authors also discuss other lake pollution prevention and restoration methodologies: such as property awareness, on-site septic effluent clarification, in-lake restoration (aeration, chemical precipitation, etc.), barge mounted flotation treatment plants, algae harvesting for energy production, and lake acid rain reversal etc. Although only the LIWT-KEC technologies were used for the feasibility studies, another manufacturers' equivalent process equipment is expected to produce similar performance data, if their process equipment is optimized. For lake applications, the equipment foot-print must be small and the overall costs must be affordable. Continuous pilot plant demonstration of any manufacturer's process equipment is highly recommended. This publication is one of many professional memoirs being written by the authors.
