Abstract:

The current study was carried out to assess the pollution load in industrial effluent located at Hudiara drain and municipal wastewater collected from sewage drain passing through Shadman, Lahore and its treatment with heterogeneous species (Microspora sp., Rhizoclonium sp., Diatoms, Lyngbya sp., Dinoflagellates) of fresh water algae. Various compositions of industrial and municipal wastewater (20:80, 40:60, & 50:50) were prepared and phycoremediation process for effluent treatment was done in ponds of different dimensions to find out the optimum conditions i.e. wastewater composition (40:60) and pond size (P2). Accumulation of nitrogen (22.98 mg/g) and phosphorus (10.4ppm) in algal biomass. The maximum percent reduction for biological oxygen demand (99.8%), chemical oxygen demand (98.6%), total suspended solids (93.9%), total dissolve solids (96.5%), total kjeldhal nitrogen (97.7%), total phosphorus (99.2%), phosphate (99.2%), nitrate (98.9%) and dye (99.2%) was achieved.
