Submerged filter-horizontal flow mode
Abstract
Abstract WASTE-CONTAINING LIQUOR IS BIOCHEMICALLY TREATED IN A TANK OR CELL BY CONTINUOUSLY RECIRULATING IT THROUGH A FILTER MEDIA WHICH IS SUBMERGED IN THE LIQUOR WHILE CONTINUOUSLY WITHDRAWING A SMALL PORTION OF SAID LIQUORR. A PRESSURIZED COLUMN OF OXYGEN-CONTAINING GAS ENTRAINS AND LIFTS THE LIQUID WASTE THROUGGH AN UNOBSTRUCTED TUBE AND RECIRCULATES IT HORIZONTALLY THROUGH THE FILTER MEDIA. DURING THE LIFTING PROCESS OXYGEN FROM THE FLUID PERMEATES THE WASTE IN ORDER TO ENSURE ACTIVE AEROBIC METABOLISM. THE TANK MAY BE ARRANGED IN SERIES WITH OTHER SIMILAR TANKS UTILIZING HORIZONTAL FLOW THROUGH THE FILTER MEDIA, OR ONE OR MORE OF SUCH TANKS MAY BE ARRANGED IN COMBINATION WITH ONE ORR MORE TANKS HAVING VERTICAL FLOW THROUGH THE FILTER MEDIA, AS DISCLOSED IN MY COPENDING APPLICATION, SER. NO. 754,341, FILED AUG. 21, 1968. THE INFLUENT MAY BE EITHER RAW SEWAGE OR PARTIALLY TREATED WASTES.
