Study and Application of Various Activated Carbons and Ash used in Water Purification Techniques: A Review

Water pollution is increasing due to the different factors such as population growth, large-scale urbanization, deforestation, and unethical activities in the river or other sources of water. Various experts have been working in the field of the preparation of activated carbon from renewable energy including cost-effective technologies and products in an eco-friendly manner for various applications. This review article discusses methodologies utilized by various experts for the preparation of activated carbon for the abatement of water pollution. Biomass such as coconut shell, Moringaoleifera seed, Peanut shell, Pomegranate peel, Rice husk, Lemon shell, Banana peel, and Orange Peel are found extremely helpful in the field of treatment of the contaminated water. The reviewed literature showed that the Biomass can be isolates pollutants from contaminated water through physical, mechanical, and biological techniques and removes various physicochemical pollutants such as pH, color, DO, turbidity, conductivity, turbidity, chloride, fluoride, TSS, TDS, BOD, COD, nitrate, phosphate, and heavy metal, etc. from contaminated water.
