Control of bark landfill leachates with an anaerobic treatment system
Leachate from bark landfills can be treated biologically by simply using the landfill itself as an anaerobic filter. This is accomplished by recycling the leachate-reintroducing it below the upper surface of the landfill. A requisite for the process is that the pH of the leachate remain approximately neutral. This can be accomplished by adding some lime sludge to the landfill as a pH controlling agent. Full-scale experiments indicate a BOD reduction of 90% without recycling. The noted effect with respect to COD is a reduction of 60%. The method is successfully operated in full-scale application. The investment costs involved are very low in comparison with alternative effluent treatment systems. (Refs. 4).
