FIELD: aqua vending apparatuses.
SUBSTANCE: invention relates to flow aqua vending machines, i.e. to water distribution automatic devices taken from a water supply network subjected to multistage purification using reverse osmosis, and dispensing treated water into a water consumer container without its (water) intermediate accumulation. Technical result consists in significant increase of permeate output coefficient during reverse-osmosis treatment of water due to multistage series-parallel reverse osmosis (serial in concentrate permeate-parallel), which makes it possible to significantly reduce the amount of water discharged into the sewer (concentrate) and thereby increase the efficiency of using water from the water supply system, as well as to avoid use of a buffer reservoir for permeate in the apparatus design and thereby significantly reduce the weight of the apparatus and reduce requirements for the pump. Flowing aqua vending apparatus in the version with two-stage reverse osmosis comprises a water pre-treatment module 1, pump 2, first membrane module 3 of reverse osmosis with output 4 of permeate and outlet 5 of concentrate, second membrane module 6 of reverse osmosis with output 7 of permeate and output 8 of concentrate, drain pipeline 9, mixer 10 permeate flows, module 11 of ultraviolet water disinfection, module 12 for water dispensing into container of water consumer. Flow aqua vending apparatus in the version with three-stage reverse osmosis additionally contains the third membrane module 13 of reverse osmosis with output 14 of the permeate and outlet 15 of the concentrate.
EFFECT: technical problem consists in necessity of considerable increase of permeate output coefficient during reverse-osmosis treatment of water, which will make it possible to increase efficiency of water use from water supply network, to reduce requirements to pump, and also to not use buffer accumulation of permeate.
