Use of Solar Energy in Treatment of Pulp and Paper Industry Effluent with Hemp: An Experimental Study

The pulp and paper industries are one wastewater-intensive series around the world that produce a large quantity of wastewater. The effluent released from these industries is the major source of river pollution and aquatic pollution. This effluent consists of heavy metals, TSS, TDS, color, pH and a high number of BOD and COD. Different stages of papermaking produce different types of chemicals which are hazardous to health. Organic matter and suspended solids are considered as hazardous pollutants of the P&P industry. This paper is dealing with the experimental study of P&P industry effluent with hemp so that the desired results can achieve and effluent can safely discharge into rivers without impacting aquatic and environmental elements. The different treatment methods have been discussed in many research papers to treat the P&P industry wastewater and their remedial solutions, but the best result was given by the adsorption method of treatment as it was more versatile, effective, simple and economical in comparison to the other methods. Solar energy was tapped for the entire operation by 5 KW panels installed near the plant. After treatment, most of the parameters like pH, alkalinity, BOD, COD, TDS and TSS came in the range of Indian standards for effluent discharge.
