In present study, assessment of the effluents from seven industries including ghee, Ni-Cr plating, battery, tannery: Lower Heat Unit (LHU), tannery: Higher Heat Unit (HHU), textile: Dying Unit (DU) and textile: Finishing Unit (FU) in city zone of Faisalabad, Pakistan showed that some of them were high in some water pollutants while some were high in other types of water pollutants. Environmental pollutants quantitatively analyzed include nickel, zinc, copper, iron, temperature, pH, conductivity, hardness, turbidity, salinity, sulfate, total acidity as CaCO3, total alkalinity as CaCO3, chloride, fluoride, Total Dissolved Solids (TDS), nitrate, nitrite, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), phosphorous, sodium, potassium, calcium and magnesium. The results of present study revealed that effluents from all industries causing severe toxic metal pollution. While analysis of physico-chemical parameters showed that although all industries causing some type of physico-chemical pollution but textile industry (FU) effluents were above permissible limits in most of physico-chemical parameters analyzed. These wastewaters are normally discharged into neighboring water bodies. The treatment of any form of waste before disposal into the environment is important and ensures safety of the populace and assessment of pollution caused by effluents is therefore necessary for appropriate selection of treatment plan. |
