    Analysis and treatment of paper industry wastewater
    (University of Management and Technology Lahore, 2016) Shehzad, Aamir
    With the development of industries the environment is affected by elimination of huge amount of waste water in ponds, rivers, streams and oceans. The waste water of paper industry show alkaline nature, high levels of TDS, TSS, EC, COD and BOD, also contains toxic metals such as Lead and Zinc. This research show that the analysis and treatment of waste water of paper industry using agricultural waste (rice husk, wheat straw) and animal charcoal. The sample was collected from outlet of pulp and paper mill. The untreated waste water had pH 7.4, TDS values 1488mg/lit, EC 408µs/cm, TSS 720mg/lit, COD 478mg/lit and BOD 120mg/lit. The results of treated waste water were quite different than untreated wastewater. By using rice husk treatment, pH changed to 6.9, EC 241µs/cm, COD value to 182 mg/lit, BOD value to 61mg/lit, TDS 856mg/lit and TSS 431mg/lit. By using wheat straw treatment pH reached to 6.7 while EC 280µs/cm, COD 180mg/lit, BOD 82mg/lit, TDS 950mg/lit and TSS 520mg/lit. By using animal charcoal treatment pH changed up to 6.8, EC 228µs/cm, COD 163mg/lit, BOD 70mg/lit, TDS 707 mg/lit and TSS 380mg/lit. The results shown by animal charcoal treatment in the reducing the wastes from effluents were better than other two treatments. The elimination of Zn, Pb and Fe from waste water were studied via rice husk, wheat straw and animal charcoal treatment. The experiment was conducted by using spectrophotometer. By using rice husk treatment the percentage removal of metals was recorded as Zinc of 62%, Lead 50% and Iron 75%. By using wheat straw treatment the elimination of Zinc was observed up to 48%, Lead as 53% and Iron as 50%. By using animal charcoal treatment the percentage removing of Zinc, Lead and Iron were achieved up to15%, 17% and 31%respectively.
