Waste Water Treatment of Biomass based Power Plant

The power generation from biomass requires the water to clean the producer gas for use in engines. The water used as cleaning agent gets contaminated with organic and inorganic compound and becomes highly polluted. The study was conducted to develop low cost water treatment plant to enhance water use efficiency by increasing the recycling duration. The charcoal received from gasifier was thermally treated for its activation and used to treat the waste water. The study reviled that 0.5 to 1.0 cm charcoal with 35 cm bed height was found effective for reduction in turbidity and COD present in the effluent water of biomass based power plant.
