TREATMENT PROCESS FOR REMOVING MICROBIAL CONTAMINANTS SUSPENDED IN WASTEWATER

摘要

A treatment process is disclosed for reducing the concentration of pathogenic microorganisms in a volume of wastewater (19) that contains a substantial concentration of pathogenic microorganisms. The process includes a primary treatment facility (21), a secondary treatment facility (23), an equalization stage (25), and adding an agglomerate-promoting agent (35, 37) such as a coagulant chemical to the volume of wastewater in an agglomeration vessel (33). The wastewater is then passed through a filter cloth membrane (29) to separate greater than about 50.0 % of the pathogenic microorganisms less than 10 microns in size, and disinfected in a disinfecting facility (31). The filter cloth membrane used is constructed of random web needle polyester felt.
