Our oil water separation unit consists of plate pack constructed of closely spaced corrugated plates which are inclined at a 55° angle or more.
The waste water flows through these plated either parallel to the corrugations in "counter‐current flow" or at right angles to the corrugations in "cross flow"
Under laminar flow conditions, the short distance between the inclined plates is now the only distance over which the pollutants have to rise or sink before they are intercepted and separated from the mother fluid.
The separated layer of free oil is being skimmed off by mechanical skimmers mounted on top of unit. The removed oil is separately collected out in drums and being safely disposed off. The separated water is free from oil and the oil content is below 2 ppm is now sent to ETP for further treatment.
The installation of this unit is provided removal of oil at source and hence the ETP process is improved
