GREASE ST – Section

Grease separator limits all problems relevant to the presence of organic oils, fats and scum in channels and treatment plants. Its installation, typically located on the grey water line, upstream of a small treatment plant or, as often required by law, upstream to sewer connection preserve pipeline from clogging and increase plant efficiency.

Features

Concrete GRASE trap ST is made of a single prefabricated reinforced concrete tank.
Nominal size (NS) is the main dimensional parameter according to European standard EN 1825-1 and EN 1825-2.
The system is equipped with sludge trap to hold the heavier material and stainless steel baffles to create calm areas and grease accumulation zone.
It works only by gravity. In domestic effluent, oils and fats rise on surface by flotation and then they are accumulated and periodically removed with cleaning operation.
