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.

Fluoride Removal from Industrial Wastewater
Fluoride Removal from Industrial Wastewater

Most typically ,lime, is supplied as a dry and somewhat corrosive powder that is quite difficult to handle. Additionally, as a result of the chemistry (see our white paper referenced above), the hydroxide demand of the fluoride reduction system is met long before the Ca demand is met which means the pH ends up much higher than allowed for discharge and post pH adjust is required.
