Waste Oil Treatment

Waste oils, oily water, oil sludge from lagoons and used emulsions are posing disposal problems for the industry. Treating them using centrifugal technology from GEA Westfalia Separator is an economical and resource- conserving solution: the disposal volume is reduced and valuable fuel is recovered at the same time. With the aid of decanters and separators, water and solids are separated from the waste oils which can then be further processed. The effluent no longer contains oil and can be disposed of in an environmentally friendly way. Besides waste oils, bilgewater, oily water, oil sludge and spent emulsions can also be treated.

The direct treatment of waste oil, for example from oil changes, is of central significance. Decanters are used in the first treatment stage which rid the waste oil from impurities. These decanters are capable of processing large volumes and fibrous solids. The downstream separator then separates solid fines and water. Thanks to the high separation efficiencies, an oil can be separated that no longer has to be disposed of at high cost, but which can be sold, for example, as a base oil for power generation. The purified waste oil is in great demand as a fuel in the cement industry and in smelters.
