FIELD: water treatment.
SUBSTANCE: invention relates to operation of natural and waste water treatment station under severe climatic conditions of Siberia and Far East. Water-supply sediment is transported to waste water treatment station wherein it is mixed with water-supply sediment at ratio 1:6 expressed for dry matter. Sediment mixture is then dehydrated on sludge areas at mean daily air temperature above 0°C, while, at lower mean daily air temperature values, dehydration is accomplished on centrifuges.
EFFECT: utilized tap water sediment and increased efficiency of treatment process due to reduced consumption of flocculant used for chemical conditioning of waste water sediment.
