    Analysis and treatment of paint industry wastewater
    (University of Management and Technology, 2016) Anwar, Maqsood
    The samples of paint industry effluent were collected from outlet pipe of the paint industry located at 9 Km Raiwind road Lahore. Different techniques have been employed for the reduction and removal of heavy metal and other harmful parameters. For this purpose wheat straw, rice husk and animal charcoal were used. The samples were characterized by UV-Visible Spectroscopy. The industrial effluents included the different amount of various parameter such as pH 8.90, TDS 1860mg/lit, electrical conductivity 428 µs/cm, TSS 540mg/lit, COD 370mg/lit and BOD 120mg/lit and heavy metals such as Pb 9.4 mg/L, Zn 4.8 mg/L and Fe 0.13 mg/L. The results of untreated wastewater of paint industry effluents were quite different from treated wastewater. By using rice husk treatment the pH changed to 8.87, EC 251µs/cm, TDS 910mg/lit, TSS 343mg/lit, COD value of 140 mg/lit and BOD value of 68mg/lit and heavy metals such as Pb 4.0 mg/L, Zn 2.1 mg/L and Fe 0.06 mg/L. By the use of wheat straw for the treatment of wastewater, pH variation of 7.33, EC 290µs/cm, TDS 890 mg/lit and TSS 245mg/lit, COD 146 mg/lit, BOD 90 mg/lit and heavy metals such as Pb 3.90 mg/L, Zn 1.99 mg/L and Fe 0.05 mg/L. By using animal charcoal treatment the pH changed of 7.10, EC 215µs/cm, TDS 780 mg/lit and TSS 165mg/lit, COD 150 mg/lit, BOD 55mg/lit and heavy metals such as Pb 1.40 mg/L, Zn 0.98 mg/L and Fe 0.03 mg/L. These experiment for heavy metals analysis were done by using spectrophotometer at 510 nm. Animal charcoal reduced the concentrations of these heavy metals almost 60-75%.
