The heart of this equipment is a corrugated plate module that increases the separation surface per unit volume. Corrugated plates cause oil or hydrocarbon particles to bond together, a phenomenon called coalescence, becoming larger and increasing their separation efficiency.

• The oils float and collect at the top.
• The water, with less than 5 mg / L of hydrocarbons, comes out through the intermediate part of the equipment, separated by a deflector from the floating area.
• At the same time, the heavier solid particles settle to the bottom of the equipment and are normally collected in a frusto-conical hopper for thickening and subsequent purging of the system.

• Materials: These spacers can be made of stainless steel or fiberglass
• They can be designed to be surface-mounted, made of stainless steel, with legs and a frusto-conical shape, or buried, cylindrical and made of fiberglass (for example, buried for a car wash).
