The wastewater treatment plant can be described as a facility that combines various processes such as chemical, physical, and biological for the treatment of industrial wastewater and removing pollutants from it.

The wastewater treatment industry generates $117.2 billion revenue in 2021, and it is projected to rise to $194.5 billion in 2030, advancing at a rate of 5.8% in the coming years. It is due to the limited availability of fresh water and its worldwide increasing usage, accounting for six times rise over the last century.

Physical Waste Water Treatment

The foremost step in the treatment of industrial and sanitary effluents is the physical wastewater treatment. It prevents damage to equipment used in biological and chemical treatment. The physical wastewater treatment equipment and processes vary depending on the affluents type and desired quality of the wastewater. The wastewaters are very colored and have high biological and chemical oxygen contents. They possess high electrical conductivity and are chemically alkaline in nature.

Neutralization- Chemical Wastewater Treatment

The neutralization process involves the addition of acid or base to the water to neutralize the pH value, the iron and other polyvalent metals are highly used as coagulations in the coagulation process. This process is also utilized for separation of suspended solids from the contaminated water. According to Minnesota Rural Water Association, the selection of coagulant chemicals relies on the type of suspended solid, including other factors such as facility design, and raw water conditions.

Electrochemical Wastewater Treatment

There are numerous processes of electrochemical wastewater treatment. For instance, sewage purification involves clarification, phosphate removal, and disinfection to reduce costs as compared to the traditional processes. The electrochemical treatment process is highly efficient and minimizes the process detention time.

Mostly electrochemical water treatment methods involve electricity usage as a primary reactant for conducting the treatment process. It includes electrocoagulation, electrodialysis, electro floatation, and electrochemical oxidation.

Therefore, the wastewater treatment processes are highly utilized in various sectors such as mining, industrial, and others for disposal of wastes, and purifying the water by removing contaminants and neutralizing the pH level to make it safe for further usage.
