FLOATING POLYMER LOAD ELEMENT FOR BIOLOGICAL TREATMENT OF EFFLUENTS Russian patent published in 2015 - IPC C02F3/10 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of effluents. This load element is intended for immobilization of anaerobic and aerobic bacteria and can be widely used in treatment of effluents with low content of organic matters or at afterpurification stages. This element is composed of tubular carcass with perforated side surface and provided with rectangular radial web. The latter is made of porous polymer that makes a carrier of microorganisms. Said tubular carcass is provided with lengthwise stiffness ribs composed of the plates connected by circle-shape elements arranged at spacing of 1/6 of tubular carcass length L and making the square cutouts. Note here that tubular carcass cutout circle arc / equals 1/7 of carcass radius R. rectangular lugs are arranged radially on carcass lengthwise ribs, on carcass outer side. Length of said ribs equals that of tubular carcass L while its width makes 1/3 of its radius R. Note here that radial rectangular web is arranged between paired opposed lugs. Note also that sides of said radial web extend beyond said carcass, on its both sides, by 1/10 of its length L. Note that web width equals 1/6 of carcass radius R where L is carcass length, I is cutout circle arc length, R is carcass radius.

EFFECT: higher efficiency of cleaning.
