9/6/2012, · ALDs can effectively treat net ,acidic, mine water with a ,pH, below 5.0. At this ,pH,, ferric iron and aluminum concentrations will be very low. Intercepted ground water is typically low in dissolved oxygen, and often contains partial pressures of CO 2 higher than atmospheric levels, which allows for development of alkalinity concentrations greater than 100 mg/L as CaCO 3 .

It is therefore necessary to adjust the ,pH, in the treatment process to make the ,wastewater pH, neutral. This is particularly important if biological treatment is being used, as the microorganisms used in biological treatment require a ,pH, in the range of 6-8 and will be killed by highly ,acidic, or alkali ,wastewater,. Various chemicals are used for ,pH, control. For ,acidic, wastes (low ,pH,) sodium hydroxide, …
