Utilization of Aquatic Biomass for Wastewater Treatment
Municipal effluents from the U.S.A. and Canada generate annually more than 400,000 tonnes of phosphorus and nitrogen, a large portion of which is dumped directly into surface waters with little or no treatment. Rapid deterioration of water quality due to algal blooms and nuisance vegetation stimulated by the flow of these nutrients has reduced the usefulness of surface waters for recreation and human consumption rather alarmingly in recent decades. Eutrophication of freshwater lakes and the increasing need to treat water supplies before consumption have had undesirable socio-economic impacts all over North America. It has been well documented that the removal of phosphorus and nitrogen at the source is the most effective means of assuring that this trend does not continue unabated. While most urban centres can possibly afford advanced physicochemical treatment systems, thousands of towns and small communities in the developed world can support only the conventional lagoon treatment, hardly a solution to the ubiquitous problem.
