Changes in acidity can be caused by atmospheric deposition (,acid, rain or ,acid, shock from snowmelt), surrounding rock, and ,wastewater, discharges. Technically, the ,pH, scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ions, which make up water (H+ + OH- = H20).

Removing Heavy Metals From Wastewater
Removing Heavy Metals From Wastewater

Thus, simply ,adjusting, the ,pH, from 6.8 to 8.6 has effectively precipitated most of the dissolved metal from the water. Since all metals display similar effects, it is clear that the adjustment of ,pH, is critical when the metal is to be removed from the ,wastewater,. However, the metals now exist in another phase or state (i.e., as small solid particles).

TSS Water Course Module 11 Waste Neutralization

Neutralization involves adjusting the pH of a liquid to approach the “neutral” pH of 7.0 (neither acid nor base). The concept of pH is discussed in detail in Module 2, Section 7. Generally, neutralization involves the use of an acid (pH less than 7) to lower the pH of a tank of basic (or alkaline) liquid (pH greater than 7), or the use of a
