    Analysis and treatment of gelatin industry wastewater
    (University of Management and Technology Lahore, 2016) Ahmad, Kabir
    The study is based on the analysis of the gelatin industry waste and their possible treatments to make it less hazardous. The wastewater of gelatin industry show alkaline nature, high levels of total dissolved solids, total suspended solids, electrical conductivity, chemical oxygen demand, biological oxygen demand and also contains toxic metals such as Lead and Chromium. This research is based on the possible and cheaper treatment of wastewater of gelatin industry using agricultural waste (rice husk, wheat straw) and animal charcoal. The samples were collected from outlet of gelatin factory. The wastewater contain pH 8.5, TDS values 1700mg/lit, EC 408µs/cm, TSS 720mg/lit, COD 478mg/lit, BOD 120mg/lit, Cr 1.4mg/lit, Pb 8.9mg/lit and Fe 8.3mg/lit. This wastewater was passed through a bed of (0.5mm thick) rice husk, wheat straw and animal charcoal.The results of treated wastewater were quite promising. By using rice husk treatment, pH changed to 6.5, EC 240µs/cm, COD value to 80 mg/lit, BOD value to 65mg/lit, TDS 768mg/lit and TSS 138mg/lit, Cr 0.13mg/lit, Pb 4.1 And Fe 4.6mg/lit. By using wheat straw treatment pH reached to 6.9 while EC 274µs/cm, COD 124mg/lit, BOD 72mg/lit, TDS 930mg/lit and TSS 142mg/lit, Cr 0.05mg/lit, Pb 0.4mg/lit and Fe 4.8mg/lit. By using animal charcoal treatment pH changed up to 7.3, EC 250µs/cm, COD 130mg/lit, BOD 78mg/lit, TDS 870 mg/lit and TSS 140mg/lit, Cr 0.09mg/lit, Pb 2.1mg/lit and Fe 5.2mg/lit.
