GREASE SEPARATORS 1.OILS AND GREASES: inlet zone in which the turbulence of the inlet flow is dampened and in which the substances with a spécifie weight lower than water (oils, foams. etc...) accumulate. 2.STILLING AREA: zone into which the separated and treated effluent flows. 3.SEDIMENTS: area in which temporary accumulation of the solids (food waste. etc...) takes place.. SPECIFICATIONS TECHNICAL CHARACTERISTICS: The grease separator is a physical pre-treatment process that removes oils, foams, greases and all substances of specific weight less than that of the effluent. The grease separator is nothing more than a stilling tank in which the substances of specific weight less than water are separated by floatation (surface). Sedimentation also takes place, with a part of the suspended solids depositing at the bottom of the tank. USE: primary treatment of grey water from kitchens, washbasins, bidets, showers, baths, washing machines and dishwashers. TECHNICAL SECTION - GREASE SEPARATORS The grease separator is a physical pre-treatment process that removes oils. foams. greases and ail substances of spécifie weight less than that of the effluent. Greases and oils produced during normal domestic activities dérivé from the consumption of butter, margarine, lard and vegetable oils. They also originate from waste méat and vegetables and from some cosmetic products. Greases are insoluble in water and hâve a low density. In the presence of surface-active agents (détergents), they create stable foams of floating materials that can cause an accumulation of putrescible substances in the sewerage pipes and render oxygénation of the sewage difficult.
