HEAD FOR IMMOBILIZING MICROORGANISMS AT BIOLOGICAL CLEANING OF SEWAGE WATER AND METHOD OF ITS MANUFACTURE Russian patent published in 2005 - IPC

FIELD: cleaning of industrial and household sewage.

SUBSTANCE: invention relates to design of head for immobilizing microorganisms at biological cleaning of sewage and method of its manufacture. Proposed head is made polymeric material in form of tubular element with gauze structurized side surface and through holes for circulation of sewage water made of continuous rope of polymeric material of round or shaped section in form of several layers of coaxial screw spirals with opposite direction of winding. Screw spirals are interconnected in series in places of intersection to form through holes for circulation of sewage water in all directions of system of coordinates. Method of manufacture of head includes forming continuous rope of plasticized polymeric material by extruding and winding it onto mandrel rotating and reciprocating in horizontal plane. Screw spirals, thus formed, are series-connected in places of intersection by thermal gluing with forming of through holes.

EFFECT: improved design of head and method of its manufacture.
