Abstract:

About two-thirds of the Earths surface is covered with water, yet there is a scarcity of drinkable water around us. The rivers, lakes, seas and oceans are drowned in chemicals, waste, plastics and other pollutants. These harmful substances degrade water quality and render it toxic to humans or the environment. Hence, environmental pollution is the main vital troubles of the society. The wastewater from textile plants is considered as the most polluting of all the industrial sectors when considering the effluent composition as well as the volume produced. Textile waste water pollutants are generally causticsoda, urea, detergents, starch, wax, ammonia pigments and dyes. Nowadays, dye wastewater is becoming one of the substantial sources of severe pollution problems. The main reason is fast fashion i.e. increased demand for textile products means the proportional increase in their production linked with use of synthetic dyes. In this paper, the one of the promising method such as Coagulation-Flocculation using Jar test apparatus for the removal of dyes from the contaminated textile waste water was studied. The effectiveness of natural coagulants/flocculants as compare to chemicals were studied as industries paying more amounts for these chemical materials which increase the total treatment cost and required further setup for disposal of sludge. In this review paper, the suitability of the natural coagulants/flocculants in the treatment of textile waste water was studied and the effect of these natural biomaterials on the removal of colour, turbidity, alkalinity, BOD, TS, TSS, turbidity and COD were also studied. The employment of locally available natural biomaterials was found to be suitable, easier, cost effective and environment friendly for textile waste water treatment.
