Tightening WwTW Emission Standards - A Review of the Treatment Technologies And Their Impact On Climate Change
ISBN: 1-84507 259 0
This study examines the feasibility of meeting tighter effluent quality standards at wastewater treatment works. The impact of these tight standards on energy use, greenhouse gas (GHG) emissions and costs has been assessed. Performance of the different treatment technologies has been compared with respect to effluent quality, energy use, GHG emissions, costs, land use and sludge production. The results indicate that tight effluent quality standards can be achieved but there is a significant penalty in terms of increased GHG emissions and costs. The results of the study should allow the water industry to enter into an informed debate with the regulator regarding effluent quality and climate change issues.
