Biological ,wastewater, treatment usually works best in a pH range from 7.0 - 8.0. Remember that this is the "best" range in a general sense. In making bioaugmentation products, we have used strains with pH ranges from 3.0 (Thiobacillus) to 11.0 (alkanophilic Bacillus). The most pH sensitive process tends to be ammonia removal or nitrification.

Joyce notes that while some of the odors in sewers ,come, from wastes discharged into the sewer (e.g., fecal, grease, and ,industrial, discharges) the strongest and most noticeable odors — and those responsible for the corrosion of sewers, resulting in degradation and/or collapse — arise from inorganic compounds produced in the sewer by the natural biology.
