These chemicals can come from agricultural runoff, ,wastewater, discharge or industrial runoff. Mining operations (particularly coal) produce acid runoff and ,acidic, groundwater seepage if the surrounding soil is poorly buffered ²². ,Wastewater, discharge that contains detergents and soap-based products can cause a water source to become too basic.

If you are removing phosphorus from your ,wastewater,, you know maintaining this balance is much more difficult. Traditional phosphorus removal coagulants, using aluminum or iron-based salts, are strongly ,acidic, with a pH level of 1.5 to 2.2. The impact of this low pH is amplified by the volume required to reduce phosphorus to low discharge limits.

A pH or 7.0 is neutral and pH below 7.0 is acidic and pH above 7.0 is basic or alkaline. Modifying the ionic charge of wastewater changes the solubility of certain solids and also allows for physical solids to attract to each other. Selecting chemicals to adjust wastewater pH requires considering the chemical makeup of …

Fungi, for example, do well in an ,acidic, environment. Most bacteria and protozoa, however, grow best in neutral (pH 7) environments. Abnormal or irregular pH in biological treatment processes can result in a significant decrease in the rate of removal of organic compounds from the environment, which will affect the biochemical oxygen demand (BOD) measurements.
