Waste Water treatment by using low cost adsorbent: A Review

Waste management

Industrial, agricultural, and domestic activities of humans have affected the environmental system, resulting in drastic problems such as wastewater containing high concentration of pollutants. In most of the industry waste water treatment is mostly done by a conventional method and advance technique like ion-exchange, membrane separation etc but it required large space for establishing treatment plant and hence its required substantial financial input and their use is restricted because of cost factors. Alternative method for waste water treatment is adsorption by using activated carbon but The coal-based activated carbons is expansive. If we use cheaper alternatives low cost material for adsorption then adsorption is becoming inexpensive. Various low- cost adsorbents is also derived from agricultural waste, industrial by-products or natural materials like Neem Leaf, Pineapple Peels, Orange peel, Bentonite Clay, coal etc can be used as adsorbents for waste water treatment.
