Wastewater Treatment By Phycoremediation And Overall Removal Efficiency Analysis of Heavy Metals Parameters At Three Discharge Effluent Source in Gomti River Lucknow, Uttar Pradesh

Environmental Engineering

This present Study was undertaken to analyze the efficiency of fresh water green algae scenedesmus specie. Sewage wastewater has enrichment of many nutrients so it can be used for green algae growth for the treatment of wastewater effluent discharge the strain was cultured in wastewater for 14 days in different flasks. The heavy metal parameter of wastewater were analyzed before and after algal treatment. Scenedesmus sp. was able to enhance the pH in wastewater. After treatment with the algal strain , there was a significant removal of heavy metals and analyzed by AAS respectively. Phycoremediation is the method of using water algae for the removal of biotransformation of toxic from wastewater. In this study effluent discharge wastewater from three location in Gomti river was taken at three different month as to check the overall percentage treatment removal efficiency by analyzing all the data gathered from three month and single site concentration and treatment removal efficiency analysis is done and result shows subsequent removal. The micro algae strain is cultured in wastewater taken from three different site in Gomti river for 18 day in three different flasks and optical density absorbance of Scenedesmus species was noted at every two days after inoculation of algae in wastewater on spectrophotometer at 680nm. The highest algae growth optical density was measured at fourteen day this signifies that all values after algae treatment is taken at fourteen day. So,the Heavy metal analysis is carried out initial day i.e. before algae treatment and final value is taken on fourteen day after algae treatment. Heavy metal analysis final reading taken on fourteen day of algae growth in waste water. The present study show the reduction of wastewater by scenedesmus sp. of all three site at three different month the overall removal performance efficiency showed significant results reduction of heavy metal also showed the three month overall removal performance efficiency was increased and the scenedesmus sp. give results effectively. The result of this study suggest that Scenedesmus sp. can be used as effective removal and heavy metals by Phycoremediation technique and this technique is cost effective, ecofriendly as compare to other technique.
