Studies of a microbial mixture with useful properties for the treatment of organic sewage
Background:The importance of bacteria in the treatment of raw sewage and water purification is well known. Here, we report on Sewper Rx, a unique mix of bacteria with powerful properties for treating sewage and other water cleaning applications, and we describe properties of the bacterial components of the treatment mixture which likely account for its enhanced organic solids digestion and odor reduction.
