PHYCOREMEDIATION OF INDUSTRIAL WASTEWATER USING MICROALGAE ( SCENEDEMUS ABUNDANS) AND BIODIESEL PRODUCTION

Abstract

The present demand of energy is gelling Fulfilled by the fossil tuck but our future is going to he in darknessas the energy providing sources are going to be exhausted in coming 2-3 decades. The present focus of ' research these days is to find an alternative lr these fossil fuels. Cultivation ol miCroalLae in wastevatcr sources ncli in nitroiien and phosplirus for bioniass production and later hiodiesel production from the extracted lipids have found to he quite pi'oiiiiing in this regard. A large number of microalgae and several vastewater sources from municipal wastewater to industrial wastewater have been eniploved till now. This study deals with the use of Scenedesnius ahundans in two di l'trent media viz. BC- Il and BBI\I 19 along with two different sources of wastewater viz, sewage wastewater from Saharanpur %IunicipaI \Vastewater Treatment Plant and Star Paper \lill. Saharanpur. Two media were taken to check which gi es best result in acclimatized or nutrient sufficient media. Four dit't'erent combination of wastewater samples are made with the use of' both wastewater sources in the ratios (MWW I P\4WW 4, MMW 2 1 PMWW 3. MWW 3 PMWW 2. MMW 4 ± PMWW I ). Maxinium biomass were found in acclimatized media l'roni both the cultures. Water qual itv parameters were checked along with biomass production and lipid production for biodiesel production. BOD reduction was achie ed in the range of' X7.1 6 to 90.29 0 and ('OD redLiction was obtained between 76.8' to 80.58 N utrient i'emo\ il was observed between 48- 2 00 for phosphate and 7- I o for nitrate. Biodiesel ohtaiiied v as 10011(1 directly related to amount of, b ioniass produced. The physical parameters for biodiesel qual it\ like W. ('N etc. ei'e found as prescribed by different standards.
