10/4/2016, · In, pH acid, conditions, these groups are protonated (–OH 2 +, –NH 3 +) and make the adsorption of metal ions to be reduced. As, pH value increases,, the degree of protonation of functional groups decreases. This influences the process forming of complex coordination bonds between the metal ions and functional groups.

Biological treatment, which is commonly used for the ,treatment, of ,wastewater, usually involves the addition of a cultured bacterial strain to the ,wastewater,, which is targeted at degrading specific pollutants ().The advantage of using ,biological, treatments is the negligible or reduced amount of chemicals involved as well as them being a totally environmentally friendly process.

Lesson 8: Nitrification and Denitrification
Lesson 8: Nitrification and Denitrification

The nitrification process produces acid. This acid formation lowers the pH of the biological population in the aeration tank and can cause a reduction of the growth rate of nitrifying bacteria. The optimum pH for Nitrosomonas and Nitrobacter is between 7.5 and 8.5; most treatment plants are able to effectively nitrify with a pH of, 6.5 to 7.0.

Application of Red Mud in Wastewater Treatment

Red mud, (RM) is an industrial waste produced in large amounts during alumina extraction from bauxite. Its disposal generates serious environmental pollution due to high alkalinity. Therefore, a strategy for the effective utilization of RM must be developed. For instance, RM may be transformed into useful products, such as adsorbents. Given its high concentrations of aluminum oxides, iron ...
