API Oil/Water Separator – PU-API-525-1

API Separator with integral chain and flight surface conveyor/solids collector. The separator tank is constructed from corrosion resistant polypropylene with a coated steel support structure and stainless steel cover. Internal conveyor components are constructed from FRP and non-metallic materials.

A baffled inlet quiets and distributes the flow to the separation area. Solids settle while oils and floating material rise to the liquid surface. The chain and flight conveyor extends the full length and width of the separator section. The conveyor will continuously drag the separator floor to remove settled particulate while pushing floating oils and solids to the adjustable, slotted pipe skimmer.

Clarified liquid enters the effluent chamber via overflow weir where it is discharged from the unit. The API Separator includes all necessary internal piping, fasteners and other internal appurtenances required for correct operation. Motor starter/disconnect for the conveyor is required by customer, or can be provided as an option.

This system is suitable for many applications to reduce TSS (total suspended solids), free oil, and other contaminants that will separate by gravity. The corrosion resistant non-metallic construction will withstand attack from aggressive acids and alkalis that may be present in the liquid stream.
