At Manisa Organized Industrial District (OID) chosen as pilot study area, a detailed wastewater profile and pollution control study has been realized. A pretreatment strategy was determined and a wastewater management plan was prepared. Existing central treatment plant was studied and cost items were determined. These evaluations were compared with the redesign options generated from our own wastewater management plan. Same treatment units and their combinations were successively designed for variable flow rates between 100-50,000 m3/d. Thus data for new OIDs of similar nature as Manisa, an optimized treatment scheme as well as its approximate cost varying with the wastewater inflow was generated. Proposals for preparing environmental criteria to be considered and applied in newly establishing or planned OIDs are summarized.
