The Environment Agency's PPG3 requires that discharge from pressure washers must discharge to a foul drainage systems. Where there is no foul drainage available, the effluent must be contained within a sealed drainage system or catch pit for disposal by a licensed waste contractor.
Silt build-up is the main problem with washdown facilities. The Conder CWS range of washdown and silt separators is used to remove the silt and will allow some separation of hydrocarbons.
Detergents that are used in wash down areas will break down and disperse the hydrocarbons, hindering the separation process. Therefore, it is important to remember that the main function of wash down separators is to remove silt.
Although it is recognised that single stage separators provide the most efficient separation, 2 and 3 chamber CWS silt separators are available on request.
