NOVELTY - Improving a wastewater treating process employing one of activated sludge or a sequencing batch reactor, involves introducing into at least one reactor tanks of an activated sludge treatment process or a sequencing batch reactor at least two agents selected from synthetic growth support media, zeolite materials e.g. clinoptilolite, and biological agent; removing ammonia; denitrification; removing chemical oxygen demand and biological oxygen demand; reducing surfactant interference; and removing phosphate and odor removal.    USE - For improving wastewater treating process e.g. for improving an activated sludge sewage treatment (claimed), such as sanitary wastewater; and for retrofitting an activated sludge process.    ADVANTAGE - The method improves overall efficiency of the process by incorporation of a combination of synthetic growth support media, zeolitic materials and biological agents in either a container to be submerged in the wastewater bio-reactors and/or directly in bio-reactors with proper screening.    DETAILED DESCRIPTION - Improving a wastewater treating process employing one of activated sludge or a sequencing batch reactor, involves introducing into at least one reactor tanks of an activated sludge treatment process or a sequencing batch reactor a quantity of at least two agents, removal of ammonia, denitrification, chemical oxygen demand (COD) and biological oxygen demand (BOD) removal, reduction of surfactant interference with liquid solid separation, provide a balanced nutrient formulation in the wastewater, phosphate removal and odor removal. The agents are selected from synthetic biological growth support media, a natural zeolitic material being one of clinoptilolite, mordenite, chabazite or phillipsite and cultured bacterial agents to effect at least one of an increase production of extra cellular polysaccharides for better liquid solid separation. The method involves placing the agents in a perforated cylindrical vessel to be submerged in a moiety of the wastewater being treated. The container is fitted with at least one of a mixer, sparger or aeration device. The method involves placing the agents in a perforated bag to be submerged in a moiety of the wastewater being treated. The method utilizes aerobic, anoxic, anaerobic, and/or quiescence processes. The method involves mixing the zeolitic material with alumina, silica, hydroxide, hydroxide precursors, and calcium oxide with a silica to alumina ratio of greater than or equal to 2.5.
