Grease Separator

In premises where wastewater containing fat and oil accumulates, the wastewater must be cleaned through a grease separator before it can be discharged into the drain. A grease separator operates according to the principle of phase separation. It consists of a separation zone, a fat collector, a sludge trap and a sampling point. The system reduces the flow rate of the wastewater so that solids, such as food wastes, sink and settle in the sludge trap. The contaminants with lower density than water, i.e. fats and oils, float on the water surface. The wastewater liberated from the fat is fed into the main drainage system. The choice of the nominal size of the separator is stipulated in EN 1825. In addition, it is necessary to comply with the wastewater regulations of the relevant local/water authority (e.g. emptying every 14 days; or  monthly with local/water authority approval).
