AERATOR Russian patent published in 2015 - IPC C02F3/00 B01F3/04 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of effluents and can be used for biological treatment of effluents in aerotanks with active mud. Aerator opposed lengthwise solid sections of resilient hose are partially interconnected to make a two-layer horizontal band with lengthwise mirror axis aligned with lengthwise mirror axes of said lengthwise solid sections. The latter are contracted by fasteners between lengthwise stiffness elements to make two equal tubular perforated resilient membranes on both sides of two-layer horizontal band to horizontal parallel axes. Note here that hose round cross-section cavity is divided into two cavities of round cross-section. This allows the production of two parallel lengthwise air efflux peaks at air dispersion simultaneously from two tubular perforated membranes of aerator. This allows improvement of fluid aeration owing to expansion of finely dispersed aeration zone on both sides of each lengthwise peaks of aeration instead of one lengthwise peak.

EFFECT: higher efficiency of fluid aeration.
