FIELD: aqua vending machines.
SUBSTANCE: invention relates to vending machines for drinking water obtained from the water of the public water supply mains through its multi-stage purification using reverse osmosis, which is characterized by the intermittent nature of its functioning. The hardware-software system comprises booster pump 5, membrane 6, hydraulic accumulator 12 and controller 18. Booster pump 5 is included in the gap of common inlet pipeline 3 with the possibility of program control using controller 18 by booster pump 5 asynchronously carried out by two processes of supplying water to membrane 6 through common inlet pipeline 3: the process of supplying the source water through inlet pipeline 1 controlled by the controller and through common inlet pipeline 3 using booster pump 5, and the process of supplying purified water from hydraulic accumulator 12 through common inlet pipeline 3 and through pipeline 16 controlled by controller 18 of the return supply of purified water to membrane 6 using booster pump 5. Controller 18 provides diffusion exposure of purified water inside membrane 6.
EFFECT: increased efficiency of non-chemical membrane cleaning (cleaning with permeate) and, as a result, increased duration of its effective operation with the possibility of increasing the degree of permeate yield.
