The Allied Pumps’ Coalescing Plate Oily Water Separators Package combines a moulded polyethylene, fibreglass or stainless steel chamber and high efficiency coalescing plate pack with a range of positive displacement diaphragm pumps and automatic controls to treat run off water containing free oil particles.
The Allied Coalescing Plate Oil Separator is an enhanced gravity separator capable of removing oils and fine solids. The unique patented plate construction and plate material serves to multiply its efficiency in comparison with other gravity based devices.
Oily water influent is either pumped or flows into the inlet chamber under gravity. The heavy solids then settle out and the 100% oil slugs rise immediately to the surface. The remaining oily water mixture flows through the plates and both the smaller oil droplets and fine solids are progressively separated. Downstream a baffle or oil dam prevents the collected oil from entering the outlet weir. Maintenance of the Coalescing Plate Oil Separator is simple and can be carried out ‘in-house’.
The Coalescing Plate Oil Separator Technology efficiency far exceeds that of a settling tank or conventional plate separator systems. The plate packs remove oil droplets 20 microns or smaller, compared to 60 microns for conventional plate separators with 3/4″ spacing and 120 microns for standard API tanks. This enables the separator to reduce effluent free oil content to levels of less than 15ppm over a wide range of influent conditions.
