Method and apparatus for washing trades equipment

摘要

A method of washing trades equipment comprising directing a wash fluid in a substantially clean state supplied from a supply tank by a first pump through a nozzle, at the equipment. Collecting the now contaminated wash fluid within a receptacle into a collection tank positioned above the supply tank. The wash fluid in the collection tank dosed by a coagulant is allowed to separate into relatively clean wash fluid above a layer of sediment in the collection tank, and at least a portion of the relatively clean wash fluid in said collection tank is discharged into the supply tank under the influence of gravity. Periodically a second pump is used to pump sediment and wash fluid to a filter assembly and that under the influence of gravity wash fluid passes through the filter assembly thereby by leaving behind a substantially de-watered sediment in the filter assembly.
