FAMILY is a grease trap entirely made of high density polyethylene and suitable for private residences or small buildings installation.

Grease traps are important components in wastewater treatment and are utilized for the preliminary treatment of gray water sewage coming from kitchen sinks, washing machines, wash tubs and showers. The volume of a grease trap tank is designed to provide an adequate residence time of the incoming wastewater. During this period fats, oils and greases (FOG) are separated from the water by the physical process known as flotation which takes place because the specific weight of these substances is equal or less than the one of the water, therefore in non turbulent conditions, they float on the surface of the tank from where they can be easily removed.Inside grease trap also sand, debris and other suspended solids are separated from the water and having a greater specific weight they settle on the bottom of the tank.

ISEA’s grease trap FAMILY is provided with PVC inlet and outlet piping. Access to the plant is by two inspections portholes, one in the flotation chamber and the other by the outlet pipe. Both ports are protected by screw-on covers.

EXCAVATION Dig a hole of appropriate dimensions. The bottom of the excavation must be leveled and compacted with a 10 cm layer of fine sand (grain size 0-5 mm).

PVC pipes and fittings are utilized for connecting the grease trap to the inlet and outlet lines.

Periodically verify that no large bodies obstruct the sewage inlet or outlet by opening the inspection ports. Also, check that no sand obstructs the outlet pipe.At least once a month check that the grease is not lower than the outlet pipe. Floating material must be removed periodically using a specialized company and disposed in appropriate sites.

BACKFILLING Fill the tank with clean water before backfilling to avoid collapse of the polyethylene structureduring backfilling. Once the tank is full, dump sand around the tank and level it. For a walk-onsolution build a 5 cm thick light concrete layer on top of the tank and finish with a 40 cm thick soil. For a drive-on solution a reinforced concrete slab is required to protect the tank. Accessible manholes are required for inspection and maintenance.
