Adjusting pH of wastewater & a bit about alkalinity too ...

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.

Investigation on the 5l absorber revealed that ratio of brewery ,wastewater, (BW) flow rate to biogas flow rate of 4.6-5.2 was optimum for minimum consumption of CO(2) for acidification. The acidified BW after the absorber was treated in UASB reactor with optimum organic loading rate (OLR) of 23.1 kg COD/m(3)/day and hydraulic retention time (HRT) of 2h.

To neutralize the highly acidic wastewater from a cation resin regeneration, a supply of alkaline liquid is needed. An anion resin regeneration is usually performed at the same time, and its wastewater is alkaline. When these two wastewater streams are combined, the pH is “neutralized” and approaches 7. If the resulting pH of the
