ULTRAFILTRATION PLANT FOR OLIVE VEGETATION WATERS BY POLYMERIC MEMBRANE BATTERIES

Within the reconversion activities of the industrial complex of S. Enf emia Lamezia (Ct, Italy) into an environmental service plant system, a vegetation water treatment plant was started in November 1995 suitabl e to treat a nominal capacity of 300 m(3)/d flowing from olive-oil mil ls. The treatment plant is based on the following steps: 1) Dirty wate r storage, 2) oil removal system, 3) Settling of suspended solids, 4) Tangential filtration on polymeric membrane, 5) Eluate treatment by me ans of polymeric membranes in a double-step biological process complyi ng with Italian standards. The finaI reconversion of the industrial co mplex into an environmental service plant system will be composed of a sewage treatment line, an oil vegetation treatment line, a solid wast e incineration line, and a compost solid waste line.
