Abstract

Modern technological developments have multiplied the hazards to which human beings, animals, plants, flora and fauna are exposed. Environmental pollution today has become a threatening menace to the survival of life in our planet, which is necessary to be reduced. The investigations are undertaken to develop an effective anaerobic biomethanation of rubber processing industry wastewaters using actively digested sludge from aerobic sewage plant for biogas generation, a future fuel, and removal of pollution loads in three-phase fluidized bed reactor. Attempts are made to optimize digestion time, feed pH, feed temperature and feed flow rate for maximum biomethanation production and maximum pollution abatement of COD (Chemical Oxygen Demand) and BOD of rubber processing industry wastewaters in three-phase fluidized bed reactor. The optimum digestion time is 6 hrs and optimum initial pH of feed is observed as 5. The optimum temperature of feed is 55 ºC and optimum feed flow rate is 6 L/ min. The maximum COD and BOD reduction of the rubber processing industry wastewaters are 87.65 % (w/w) and 89.25% (w/w) at optimum biomethanation parameters. The maximum biogas yield rate is 0.674 m³ /kg COD m^-3 hr^-1 with maximum methane gas (CH₄ ) yield rate of 0.456 m³ /kg COD m^-3 hr^-1 at optimum biomethanation parameters.
