HYDRODYNAMIC PLANT FOR POST-TREATMENT OF TAP DRINKING WATER Russian patent published in 2019 - IPC C02F9/08 C02F1/34 C02F1/74 C02F1/20 C12M1/33 

FIELD: ecology.

SUBSTANCE: invention relates to ecology and can be used for disinfection and purification of tap water in residential and/or public buildings, the contamination factor of which by chemical and bacteriological oxygen demand LV = (COD + BOD) exceeds the standards for drinking water established by Gossanepidnadzor. Hydrodynamic installation (HDI) of post-treatment of tap water of a residential and/or public building comprises in-series installed working pump 6 and disintegrator 9. Before disintegrator 9 there is confuser 8 made at the narrowing angle β= (20±5)° with length L = (0.1–0.15) m and outlet cross-section diameter d = (0.02–0.04) m with possibility of increasing water flow rate to W≥10 m/s. Working pump 6 is made with capacity Q = (20–60) m³/ hour and outlet pressure P = (20±5) kg/cm². Disintegrator 9 has diameter of flow section d = (0.02–0.04) m, length L = (4–6) m and is connected through metering device 34 and constant pressure reducer 33 to source of compressed atmospheric air 31.

EFFECT: invention enables to obtain environmentally safe clean and decontaminated drinking water from contaminated tap water.
