FIELD: process engineering. ^ SUBSTANCE: invention relates to centralised domestic water consumption, in particular, in treatment of low-turbidity blood waters. Proposed method comprises coagulating water dirt, flocculation, settling at continuous circulation of a portion of flakes, filtration through granular packing with cyclic washing, and recovery of washing waters. Note here that dirt washed from packing is dispersed and directed in zone of mixing treated water with circulated flakes. ^ EFFECT: stable high quality of treatment, reduced consumption of coagulant. ^ 2 cl, 1 dwg, 2 tbl, 1 ex |
