Degreasing is a physical pre-treatment to remove oils, foams, greases and all substances that have a specific weight lower than that of the sewage. The degreaser is a stilling tank in which the separation by flotation (rising) of substances with a specific weight lower than that of water takes place and the sedimentation of a part of the suspended solids that deposit on the bottom of the tank.

POSSIBLE USE: primary treatment of gray water from kitchens, sinks, bidets, showers, bathtubs, washing machines and dishwashers, etc.

Rototec gravity degreasers consist of a polyethylene tank inside which two semi-submerged inlet and outlet pipes are arranged at different heights, the useful volume is divided into three compartments:

• an inlet zone in which the turbulence of the incoming flow is dampened,
• an area where the separation and temporary accumulation of solids takes place.
• a third outflow area of the treated wastewater.
