FIELD: chemistry, water purification.
SUBSTANCE: invention can be applied in water purification. Water continuously flows by gravity from upper chamber of water-treatment system (TC) to filling chamber, from which water is sampled. Water consistently flows through filter station (CB), chemical cleaning unit (CR) and treater (SC). Chemical cleaning unit (CR) is mounted in sealed chamber with water outlet. Outlet channel design provides that water following from chemical cleaning unit is supplied to treater (SC) after preset time at least 30 minutes.
EFFECT: provided high degree of microbiological treatment in simple filtration system of water gravity flow.
