Physicochemical Analysis of Effluents from Agro-Based Paper Mill in Uttarakhand State of India
International Journal of ChemTech Research, 2020
The pulp and paper industries discharge of large amount of effluent as wastewater in the surrounding streams thereby causing serious health and environmental problems. These large quantities of effluents need to be characterized for evolving proper treatment strategy prior to their disposal. Physicochemical characteristics of effluents from an agro-based paper mills located in Uttarakhand state of India were analyzed in terms of pH, colour, TS, TDS, TSS, turbidity, BOD, COD, and AOX. The effluent samples collected from different processing units of the paper mill varied considerably across the discharge streams. The mean values pH, colour, TS, TDS, TSS, turbidity, BOD, COD, and AOX were found in the range of 2.559.8±0.05, 4102802 PCU, 1980.652785.79 ppm, 1650.672470.35 ppm, 315.44 401.35 ppm, 73.22349.37 NTU, 170.32670.42, 705.522000.55 ppm, and 14.9840.82 respectively. Result shows that all the studied physicochemical parameters of effluents at different processing units o...

Pulp and paper mills generate varieties of pollutants depending upon type of the pulping process being used. This paper presents the characteristics of wastewater from South India Paper Mill, Karnataka, India which is using recycled waste paper as a raw material. The raw wastewater consists of 80-90 mg L −1 suspended solid and 1,010-1,015 mg L −1 dissolved solid. However, pH varied from 5.5-6.8. The biochemical oxygen demand and chemical oxygen demand ranged from 200-210 and 1,120-1,160 mg L −1 , respectively. Aerobic treatment of raw effluent attribute to significant reduction in suspended solid (range between 25 to 30 mg L −1) and total dissolved solid (range between 360 to 390 mg L −1). However, pH, temperature, and

Recent studies have found paper and pulp industries responsible for polluting the environment in India by releasing hazardous liquids which contain heavy metals and other toxicants. The effluents released from these industries, pollute the water bodies. The polluted water bodies contain compounds which are toxic to aquatic flora and fauna as well as have a strong mutagenic effect. Bioremediation may serve as an appropriate method to reduce the physico-chemical parameters to a prescribed Limit by CPCB. Biological treatment has been reported efficacious in reducing the organic load and toxic effects of kraft mill effluents. The present investigation was aimed to degrade physic-chemical characteristics from effluent generated by Pulp and Paper industry. The physico-chemical analysis of effluents showed that these characteristics were notably high which was not permissible by CPCB and ISI. Based on the isolation, identification and biochemical characterization studies the isolated bacterial strain was identified as Bacillus sp.Simulated approach was utilized to monitor Physicochemical properties (DO,COD, BOD, Alkalinity, Acidity, Chloride, Hardness, Nitrate, Phosphate) after bacterial treatment. A reduction in all the physico-chemical properties was observed with post bacterial treatment which was in accordance with the standards prescribed.

Discharge of large amount of wastewater as effluent from pulp and paper industries in the surrounding streams result in serious health and environmental problems. These large quantities of effluents need to be characterized for evolving proper treatment strategy prior to their disposal. Physicochemical characteristics of effluents from an agro-based paper mills located in Uttar Pradesh state of India were analyzed in terms of pH, colour, TS, TDS, TSS, turbidity, BOD, COD, and AOX. The effluent samples collected from different processing units of the paper mill varied considerably across the discharge streams. The mean values pH, colour, TS, TDS, TSS, turbidity, BOD, COD, and AOX ranged from 1.82±0.03 to 9.84±0.06, 481.44±0.58 to 3936.16±5.76 PCU, 1718.49±0.65 to 4252.29±4.46 ppm, 1518.27±2.65 to 3032.14±3.32 ppm, 200.22±2.01 to 1220.15±3.15 ppm, 113.23±1.46 to 481.22±2.61 NTU, 355.65±3.50 to 1342.22±3.50 ppm, 881.52±3.19 to 2710.12±4.52 ppm, and 15.75±0.51 to 38.35±0.21 ppm respectively. The results demonstrated markedly higher values of all physicochemical parameters of effluents from various processing units of the paper mill than the permissible limit thus necessitating appropriate treatment prior to their discharge in the environment.

Chemical treatments of Effluents from Agro-Based Paper Mill in Uttar Pradesh State of India
International Journal For Research In Applied Science & Engineering Technology, 2020
Discharge of large amount of wastewater as effluent from pulp and paper industries in the surrounding streams result in serious health and environmental problems. These large quantities of effluents need to be treated after characterization prior to their disposal. Physicochemical characteristics of effluents from an agro-based paper mills located in Uttar Pradesh state of India were analyzed in terms of pH, colour, TS, TDS, TSS, turbidity, BOD, COD and AOX. The results found markedly higher values of all physicochemical parameters of effluents from various processing units of the paper mill than the permissible limit thus necessitating appropriate treatment prior to their discharge in the environment. In the present paper several types of coagulant viz. Ferric chloride, lime, alum and Ferric chloride with poly acryl amide(PAM) have been examined for their effectiveness of reducing chemical load of the effluent.
Bioremediation and Detoxification of Pulp and Paper Mill Effluent: A Review
Research Journal of Environmental Toxicology, 2015
Presently, 50-60 m 3 of water needed to produce a ton of paper and around 240-250 chemicals have been identified in effluents, which are produced at different stages of paper making in pulp and paper industry. The pulp and paper industry is typically associated with pollution problems related to high BOD, COD, toxicity, AOX, color, suspended solids, lignin and its derivatives and chlorinated compounds. Although numerous studies have looked ways by various researchers to remove COD, BOD, color etc. of pulp and paper effluents, the problem still persists. Number of microorganisms including bacteria, fungi and actinomycetes has been implicated to degrade the xenobiotic compounds present in pulp and paper mill effluent. This article review the origins and effects of major pollutants present in pulp and paper mill effluents and the progress made in their reduction through fungi, bacteria, algae and enzymes as well as further scope is also discussed.
Decolourization of Wastewater from Pulp and Paper Mill Effluent by Using Isolated Fungus
2015
Three fungal strains were collected from decomposed woods in Kyaukse wood mill and five fungal strains from effluent sludge by continuous pulp and paper industry. Among the accumulated strains, WF4, WF5, WF8, SF1 and SF3 are able to grow up well on agar containing some pieces of powdered bamboo and sawdust indicating that they could utilize these powders as nutrient for their growth. When they were tested for their effectiveness on decolourization of the wastewater from the pulp and paper industry, it indicated that strain WF5 was the most efficient strain which has the ability to decolorize the wastewater by (58%±0.4) and degrade the lignin by (3104±232) respectively.
