Towards a Patent for a New Wastewater Treatment Process: Chemically Enhanced Primary Wastewater Treatment and the Use of Chitosan in Chemically Enhanced Primary Wastewater Treatment.

摘要

The paper describes two inventions. The first invention is 'chemically enhanced primary wastewater treatment' which is a unique application of known processes. The defining characteristic of the wastewater treatment method is the maximization of the efficiency of the first stage in the wastewater treatment regime. Chemically enhanced primary wastewater treatment is distinguished from other methods of chemical wastewater treatment by small dosages of a metal salt(s) (< 50 mg/1), small dosages of a polyelectrolytic polymer(s) (< 1.0 mg/1), high overflow rates, and minimal follow-on biological treatment approximately 50 percent reduced in size compared to standard wastewater treatment schemes. The invention has been developed through the joint efforts of Donald R.F. Harleman, Shawn Morrissey, and Susan Murcott. The second invention is the application of chitosan in chemically enhanced primary wastewater treatment. The second invention is the joint work of Donald R.F. Harleman and Susan Murcott.
