Abstract

Zgłoszenie dotyczy układu i sposobu oczyszczania wody. Układ zawiera komorę (1) flotatora, zespół membran filtracyjnych (2), źródło wody (3) do filtracji, generator (4) mikro-nano pęcherzy, pompę (5) płukania membran, zbiornik filtratu (6), pompę (7) filtratu, zgarniacz osadu (8), zbiornik osadu pofiltracyjnego (9). Komora (1) flotatora połączona jest za pośrednictwem rurociągu (10) z generatorem (4) mikro-nano pęcherzy, do którego podłączony jest rurociąg (11) wychodzący na zespół membran filtracyjnych (2); oraz przynajmniej jeden z rurociągów (10, 11) wyposażony jest w pompę (12). Sposób polega na tym, że woda za pośrednictwem rurociągu będącego źródłem wody (3) przepompowywana jest do komory (1) flotatora a następnie za pośrednictwem rurociągu (10), przepompowywana jest do generatora (4) mikro-nano pęcherzy, gdzie nasycana jest mikro-nano pęcherzami o średnicy od 1 do 50 mikrometrów a następnie za pośrednictwem rurociągu (11) przepompowywana jest na zespół membran filtracyjnych (2).The notification concerns the system and method of water purification. The system includes a chamber (1) for a flotation device, a set of filtration membranes (2), a water source (3) for filtration, a generator (4) micro-nano bladders, a pump (5) for membrane rinsing, a filtrate tank (6), a pump (7) for filtrate , sludge scraper (8), filter sludge tank (9). The flotation cell (1) is connected via a pipeline (10) to a micro-nano blister generator (4) to which the pipeline (11) overlooking the filter membrane assembly (2) is connected; and at least one of the pipelines (10, 11) is equipped with a pump (12). The method consists in that the water is pumped through the pipeline (3) into the chamber (1) of the flotation unit and then through the pipeline (10), it is pumped into the generator (4) of micro-nano bubbles, where it is saturated with micro nano blisters with a diameter of 1 to 50 microns and then through a pipeline (11) it is pumped onto a set of filtration membranes (2).
