PURIFICATION OF WASTEWATERS FROM OILS, LUBRICATING AND COOLING LIQUIDS

摘要

The process of wastewaters purification of emulsified oils by means of electrogenerated hydroxide of aluminum, received in the electrocoagulator at anode current density of 0.6-0.7 A/dm~2, after a stand in the chamber of floes formation at slow hashing, was investigated. It is possible to achieve the purification up to 98-99 percent by using the electrochemical method, combining electroprocessing with the soluble aluminum anodes, and subsequent electrochemical processing with insoluble electrodes.
