Many industrial wastes contain ,acidic or alkaline, materia ls that require neutralization prior to discharge to receiving waters or prior to chemical or biological treatment. (Eckenfelder, 2000) Neutralization is the process of adjusting the ,pH, of water through the addition of an acid or a base, depending on the target ,pH, and process requirements.

concentration of the metal, and the pH of the water. Heavy metals are usually present in wastewaters in dilute quantities (1 - 100 mg/L) and at neutral or acidic pH values (< 7.0). Both of these factors are disadvantageous with regard to metals removal. However, when one adds caustic to water which contains dissolved

A ,pH, less than 7 is ,acidic, and a ,pH, greater than 7 is ,alkaline,. The ,pH, scale is logarithmic so for every one unit of change in ,pH, there is a tenfold change in ion concentration. This means a solution with a ,pH, of 3 is 10 times more ,acidic, than a solution with a ,pH, of 4 and 100 times more ,acidic, than one with a ,pH, of 5.

Surface water typically has a pH value of 6.5 to 8.5 (7 represents neutral on a scale measured from 0 to 14). Acid water is classified as water with a pH value lower than 7. Household liquids considered naturally acidic are coffee and vinegar. Household items with a pH above 7 – common examples include baking soda and soap – are alkaline.

When ammonia is added to the soil it reacts with water to form ammonium-N, which is an ,alkaline, reaction that initially raises the ,pH, of the soil. However, as ammonium-N undergoes nitrification acidity is produced. These two reactions (the ,alkaline, reaction of ammonia and the acid reaction of ammonium-N) do not quite balance out, but come close.
