Abstract
Introducing a combination of suspended attached growth Medias and biological reactants into a sewage treatment process with or without additional reaction to improve and increase capacity of a given process. Media and biological reactants can be disposed in a perforated container or flexible container that can be submerged in a sequencing bed reactor or the aeration and/or mixing tanks of an activated sludge sewage treatment process.
Claims15
A method for improving a wastewater treating process employing one of activated sludge or a sequencing batch reactor comprising the steps of introducing into one or more of the reactor tanks of an activated sludge treatment process or a sequencing batch reactor a quantity of synthetic high surface area biological growth support media together with a separate natural zeolitic material being one of clinoptilolite, mordenite, chabazite or phillipsite and one or more separate cultured bacterial agents to effect one or more of an increase production of extra cellular polysaccharides for better liquid solid separation, removal of ammonia, denitrification, COD and BOD removal, reduction of surfactant interference with liquid solid separation, provide a balanced nutrient formulation in the wastewater, phosphate removal and odor removal.
A method for improving a wastewater treatment process utilizing aerobic, anoxic, anaerobic, and/or quiescence processes comprising the steps of introducing into said wastewater during an aerobic, anoxic, anaerobic or quiescence process a quantity of a synthetic biological growth support media, a separate natural zeolitic material and separate cultured bacterial agent, the mixture adapted to produce pollutant removal at ambient temperatures at or above 4° C. (39.2° F.).
A method for improving activated sludge sewage treatment process by introducing into said process a mixture of high surface area synthetic biological growth media, a separate natural zeolitic material being one of clinoptilolite, mordenite, chabazite or phillipsite and one or more separate cultured bacterial agents to effect one or more of an increased production of extra cellular polysaccharides for better liquid solid separation, removal of ammonia, denitrification, COD and BOD removal, reduction of surfactant interference with liquid solid separation, provide a balanced nutrient formulation in the wastewater, phosphate removal and odor removal.
A method for improving a wastewater treating process employing a sequencing batch reactor comprising the steps of introducing into one or more of the reactor tanks of a sequencing batch reactor a quantity of synthetic biological growth support media together with a separate natural zeolitic material being one of clinoptilolite, mordenite, chabazite or phillipsite and one or more separate cultured bacterial agents to effect one or more of an increased production of extra cellular polysaccharides for better liquid solid separation, removal of ammonia, denitrification, COD and BOD removal, reduction of surfactant interference with liquid solid separation, provide a balanced nutrient formulation in the wastewater, phosphate removal and odor removal.
