FIELD: treatment of sewage; cleaning oil-containing water from oil and mechanical impurities.
SUBSTANCE: proposed device is made in form of inclined pipe divided into sections for separation of water and oil and coalescing section filled with granules of hydrophobic material by 0.5-0.7 volume for their free motion. Sewage water is delivered by means of collector provided with branch pipes smoothly located over length of coalescing section.
EFFECT: increased operation cycle and productivity due to self-regeneration of granules of hydrophobic material.
