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 (upward flow to the surface). Sedimentation also takes place, with a part of the suspended solids depositing at the bottom of the tank
1. OILS AND GREASES: inlet zone in which the turbulence of the inlet flow is dampened and in which the substances with a specific weight lower than water (oils, foams, etc…) accumulate.
2. STILLING AREA: zone through which the separated and treated effluent flows
3. SEDIMENTS: area in which temporary accumulation of the solids (food waste, etc…) takes place
