The effectiveness of oil sewage purification by filtration on carbon—lime bed was studied, the voluminal ratio of carbon ash to waste lime was equal to Vc/Vcn = 0,25; 0,375; 0,5; 0,625; 0,75; 1,00. The ether extract, COD, absorbance and inorganic contaminations with components of bed such as Ca+2, Cl~ were determined. The effectiveness of sewage purification increased as the quantity of sewage increased. The effectiveness of sewage purification on regenerated bed and permeability of the bed after regeneration were similar to those for new—prepared bed.
