System for pollution suppression

A two stage oxidative process for disinfection of material containing a distribution of ammonia-ammonium compounds, comprising,

• adding a primary oxidizing agent to the material to disinfect and to reduce the pH level of said material,
• said primary oxidizing agent selected from the class consisting of ferric chloride and aluminum chloride,
• adding a secondary oxidizing agent to the material to obtain a very low bacteria count and a substantial amount of ammonium compounds,
• said secondary oxidizing agent selected from the class consisting of chlorine, chlorine dioxide, ozone and sodium hypochloride,
• the amount of said primary oxidizing agent added is sufficient to cause said pH of said material to be 7.0 or less,
• said amount of primary oxidizing agent being at least 50 parts per million,
• the amount of said secondary oxidizing agent being at least 0.7 parts per million for ozone and at least 4.0 parts per million for said chlorine, chlorine dioxide and sodium hypochloride,
• said material being selected from the class consisting of sewage effluent, potable water and process water,
• the amount of said ammonium compounds to said ammonia compounds produced being at least 97 percent,
• said primary oxidizing agent being added to a first stage and, said secondary oxidizing agent being added to a second stage,
• said second stage having a conduit located therein, said conduit containing a turbulence-causing device,
• said turbulence-causing device being a flat plate orifice, an injection tube having a tip extending through said flat plate orifice,
• said tip of said injection tube being located in the vena contracta portion of said flat plate orifice, and said secondary oxidizing agent being injected into said conduit through said injection tube.
