Investigation on Physicochemical Parameters of Tannery Effluent
Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 3
Abstract
This study was accomplished to find out the qualities of tannery effluents with the assessment of Physicochemical parameters of effluents liberated by the tanneries in Dhaka, Bangladesh. Effluents were gathered from nine tanneries and three ejected points of area Hazaribagh, Dhaka. Various physical and chemical properties like Alkalinity, Biological Oxygen Demand , Chemical Oxygen Demand , Chloride, Color , Dissolved Oxygen , Electrical Conductivity , Nitrate, Odor, Phosphorous, , Sulphate, , Suspended Solid, Temperature, The pH, total Dissolved Solids etc. were evaluated and matched up to standard levels .The observed ranges of the values are 1072-3833 mg/L for TSS, 1251-6240 mg/L for COD, 3.2-10.43 for pH, 2375- 4385 mg/L for TDS, 200-1257 mg/L for BOD5, 7.81-13.85 mg/L for phosphorous, 2100-9745.8 μs/cm for EC, 684-1020.2 mg/L for alkalinity, 2.85-22.34 mg/L Cr3+, 8-26 mg/L for NO3- ,484-1928 mg/L for Cl-, 0.68-2.8 mg/L for NO2- and 124-512 mg/L for SO42-.
