abstract
Sludge refers to the residual, semi-solid material left from industrial wastewater or sewage treatment processes. The present investigation for the bioremediation of sludge the samples were collected from different places near Jalandhar city of the Punjab (India). Experimental studies revealed a broad range in metal extraction efficiencies of the different extraction technologies. In order to analyse the sludge, the physiochemical parameters like pH, Moisture and heavy metal are determined. The bacterial strain Pseudomonas aeruginosa was screened for the removal of heavy metal like LEAD and COPPER from the industrial sludge. The effect on pH and moisture was determined. Maximum lead removal was noted to be 2.09 by Pseudomonas aeruginosa species from the sludge sample and copper removal was noted to be 2.65 by P. aeruginosa species. The present study depicts that the bacterial species remove heavy metal from sludge and can be used for the industrial waste management and other environmental maintenance.
