DEVICE AND METHOD FOR LIQUID PURIFICATION Russian patent published in 2016 - IPC B01D35/26 

FIELD: chemistry.

SUBSTANCE: method for liquid purification consists in filling receiving reservoir with non-purified liquid, realisation of cycle of operation of automatic device regulated in time of gas injection with closing water purifier cover by injection of gas into receiving reservoir for non-purified liquid, under pressure of which non-purified liquid passes from receiving reservoir for non-purified liquid through filtering unit into receiving reservoir for purified liquid, with gradual reduction of excessive gas pressure to the end of filtration process with possibility of further repetition of cycle of operation of automatic device of regulated in time gas injection. Non-purified liquid under pressure is replaced from receiving reservoir for non-purified liquid with gas volume, larger than volume of non-purified liquid in receiving reservoir for non-purified liquid, and after switching off automatic device of regulated in time gas injection, liquid, remaining in receiving reservoir for non-purified liquid, passes through filtering unit into reservoir for purified liquid under pressure of excessive gas volume. Device for liquid purification contains receiving reservoir for non-purified liquid, connected with automatic device of regulated in time gas injection in filtration mode by means of connective element, including pneumatic gas injection unit, control unit and power source, reservoir for purified liquid and filtering unit with means for liquid input and output.

EFFECT: increased degree of liquid purification with simultaneous reduction of time for liquid purification process.
