Water settling tanks with liquid filter
Water settling tanks with liquid filter are intended for waste-water treatment. The water enters the tank after the produced water process units and after oil dehydration at oilfield enterprises. A special feature of this type of settling tanks is a liquid filter that allows to remove various mechanical impurities and suspended particles.
The Saratov Reservoir Plant produces water settling tanks with filters with a volume of from 50 up to 200 m3.
Design and internal arrangement of water settling tanks with liquid filter
Structurally, settling tanks are made in the form of a horizontal vessel with elliptical heads on saddle supports or legs. Manholes and fittings are located along the shell for installing the necessary technological equipment: operating medium inlet and outlet pipes, drainage, gas outlet, pressure gauges, level gauges, safety valve, etc. The equipment composition is selected at the design stage and depends on the Customer's requirements and features of the technological process on the site.
There is a distribution unit inside the water settling tank, through which waste water enters the tank and goes onto the filter surface in single splits. A hydrophobic liquid filter is a layer of oil that "captures" and collects oil particles and any suspended particles contained in water. When the filter absorbs the maximum possible amount of oil, it (the filter) is removed from the tank. The treated water is collected under a liquid filter, and mechanical impurities are separated from the water by hydrostatic pressure.
