A METHOD OF RECOVERY AND TREATMENT OF WASTE COOLANT FOR RECYCLING

摘要

In the method and apparatus for recovery and treatment of waste industrial coolant for recycling and reusing by collecting contaminated coolant into a skimming tank, trapping the free floating tramp oil on the surface of the coolant, scrapping the trapped tramp oil from the skimmer surface, pumping the resultant coolant to an Oil Trace Remover and traping the traces of the tramp oil, trapping the particulates matter after passing the Oil Trace Remover through a filtration medium, discharge of resultant coolant to Coolant Collection Tank, doing away foul smell by elimination of biological contamination and breaking of the oil emulsion, splitting the coolant emulsion in two phases of concentrated emulsion and the water phase, draining the water phase and collecting concentrated emulsion as reject and recirculating the treated coolant through the Photochemical Reactor.
