What is chemical treatment of wastewater?
Chemical treatment of wastewater uses chemical reactants to break down pollutants. It is ideal for wastewaters with high chemical toxin contents, such as the wastewaters from chemical or pharmaceutical manufacturing, pump and paper mills, laboratories and textile manufacturers.
What are the main biochemical treatment methods for wastewater?
The presented biological wastewater treatment processes include: (1) bioremediation of wastewater that includes aerobic treatment (oxidation ponds, aeration lagoons, aerobic bioreactors, activated sludge, percolating or trickling filters, biological filters, rotating biological contactors, biological removal of …
What are the types of chemical treatment on industrial waste?
Methods include Advanced Oxidation Processing, distillation, adsorption, vitrification, incineration, chemical immobilisation or landfill disposal. Some materials such as some detergents may be capable of biological degradation and in such cases, a modified form of wastewater treatment can be used.
What is biological method of waste water treatment?
Biological treatments rely on bacteria, nematodes, or other small organisms to break down organic wastes using normal cellular processes. Wastewater typically contains a buffet of organic matter, such as garbage, wastes, and partially digested foods. It also may contain pathogenic organisms, heavy metals, and toxins.
What is sodium hydroxide used for in wastewater treatment?
Sodium Hydroxide is a strong alkali which, among other facts, means that it is highly ionized and has a high pH. Thus, in wastewater treatment these products can be used to raise the pH level of the water. It is also helpful in the process of removing heavy metal particles from the water.
What is the chemical name of Sodium hydroxide?
