Defining Alkalinity. Alkalinity is a measurement of water’s ability to neutralize ,acid,. There are 3 types of alkalinity, depending on pH of the water: bicarbonate, carbonate and hydroxide.Bicarbonate (HCO 3) has a pH ranging from 4.3 to 8.3.Bicarbonate is the most prevalent alkalinity in natural bodies of water. Carbonate (CO 3) has a pH ranging from greater than 8.3 to 10.

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.
