Abstract:

The industry is one of the most wastewater producing sectors, not only in terms of the volume of effluent generated but also in terms of its characteristics as well. Untreated effluents are irreversible to the environment when released directly into the water bodies or open lands. So we need to treat wastewater. Wastewater treatment methods include precipitation, coagulation/flotation, sedimentation, filtration, biological process, and chemical reactions. Each method has its value and cost limits in applications. Coagulation – flocculation is one of the most important physicochemical processes for industrial wastewater processing to reduce wastewater turbidity in suspended and colloidal materials. Aluminum and iron (III) salts are the two most commonly used primary coagulants. In recent studies, various drawbacks from the use of aluminum salts have been identified, such as Alzheimer's disease, Neurotoxicity, Cancer, and large volumes of sludge. The study has therefore led to these problems through some methods of natural treatment. It is easily biodegradable and less volumetric. Certain natural seeds are maize, grape seed, nirmali, pumpkin-seed, guar, ordinary bean, and many more. The conclusion was made that Hibiscus Rosa Sinensis natural coagulants obtained from MoringaOleifera showed only the same coagulation as a commercially available alum.
