Above the Ground Rectangular Tank Oil Water Separator
The above-the-ground rectangular tank oil water separator (OWS) is designed to remove free-floating oil, grease, and settleable solids from oil/water mixtures, effluent, and wastewater. It finds application in industrial and commercial setups.
Design
The above-the-ground rectangular tank oil water separator is a compact, packaged unit. It mainly consists of a primary & secondary separator chamber and an effluent discharge chamber. It is equipped with a coalescer separator for oil separation. The design of the above-the-ground rectangular tank oil water separator has no moving parts, enables large flow rates, optimized sedimentation, enhanced retention time, and provides a large surface area for oil separation.
Working
The wastewater/effluent flows in the stationary OWS from the inlet. At the inlet, the wastewater gets directed over a baffle. The baffle plays three important roles in oil-water separation. It reduces the velocity and turbulence of the incoming water. The wastewater flow is redirected downward. It reduces and distributes the flow evenly.
The contaminants such as settleable solids, settle at the bottom of the tank in the primary chamber. Whereas, concentrated oil droplets rise to the surface.
The oily water enters the secondary chamber to pass through the inclined coalescer separator. Coalescer separator intercepts tiny droplets of oil to form a giant droplet, that floats to the surface. At the same time, floating solids are intercepted on the flat top surface of the inclined coalescer plates. These floating solids slide downward into the sludge collection area. Here, the solids flow downward and oil droplets rise upwards to the surface of the water.
The difference in gravity of oil and water enables the removal of oil from the top surface. With the help of a suitable oil skimmer, oil is removed from the top surface and oil-free water is discharged from the bottom of the tank. The oil-free wastewater is either discharged as per the guidelines or recycled for reuse. Similarly, oil recovered from the surface of the wastewater is either recycled or disposed of as per the disposal guidelines.
