By the continuous addition of the IPT bacterial suspension at multiple points within the collection system, one is able to repopulate the wastewater and sewer biofilm with bacteria that excrete enzymes to rapidly degrade complex organic substrates to bioavailable substrates, and which are more flexible in their oxygen requirements, and are better adapted to the wastewater environment than the intestinal bacteria that are introduced continually through normal wastewater collection activities. The continuous addition of the IPT suspension allows a gradual repopulation of the sewer biofilm by bacteria that are more efficient at biological nutrient removal than the bacteria that are present in untreated conditions. As the bacteria grow, multiply, and reach the wastewater treatment facility, they are assisting in further degradation of the remaining COD in all phases of treatment. The newly diversified bacterial population is also more capable of supplying the products that assist the bacteria primarily responsible for nitrification, denitrification and biologically mediated phosphorus removal than the population present in untreated wastewater treatment facilities.
