DOMESTIC WATER TREATMENT DEVICE Russian patent published in 2025 - IPC C02F9/00 C02F1/78 C02F1/52 

FIELD: water treatment.

SUBSTANCE: present invention relates to water treatment devices. Device contains solid waste crushing unit, accumulation and physical and chemical cleaning unit, reagent feed unit, filtration unit, sludge dewatering unit, ozoniser. Accumulation and physical-chemical treatment unit is intended for disinfection of waste water coming from solid waste grinding unit due to reactions between at least one reagent and waste water contaminants, for waste water treatment from reacted contaminants. Reagent feed unit is intended for storage of at least one reagent and introduction of the above reagents into water taken from the unit of accumulation and physical-chemical treatment and returned to the same unit. Filtration unit is intended for treatment of waste water coming from accumulation unit and physical and chemical treatment, for destruction of residual ozone and for removal of purified water. Filtration unit comprises the following components connected in series in flow direction: coarse filter having a filtering partition with a cell size of not more than 200 mcm, medium purification filter having a filtering partition with a cell size of not more than 50 mcm, fine filter having a filtering partition with a cell size of not more than 1 mcm, and sorption filter. Sludge dewatering unit is intended for separation of sediment from water coming from accumulation unit and physical and chemical treatment, and its direction to solid waste grinding unit, as well as for dehydrated sludge discharge. Ozoniser is designed to generate and feed ozone into the reagent feed unit.

EFFECT: increased degree of water purification.
