A study of the effectiveness of oil sewage purification by filtration on a carbon-lime bed was carried out. The volume ratio of carbon ash to waste lime equalled Vc/VCa = 0.375; 0.5; 0.625 of a regenerated carbon-lime bed. The ether extract, COD and inorganic contaminations with components of the bed, such as Ca+2, Cl-, were determined. The effectiveness of sewage purification increased as the quantity of sewage treated was increased. Sewage purification by adsorption on the carbon-lime bed does not solve the problem of environment protection as pollution get transported from liquid to solid state, and oily slag heaps of the used absorbent are produced. This in consequence causes the environment pollution as well. Relating to this, there is a need to regenerate oily absorbents and reuse them in adsorption process. The effectiveness of sewage purification on a regenerated bed and permeability of the bed after regeneration are similar to those for a freshly-prepared bed.

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.
