Waste Water Treatment | Management
Cities around the world are struggling to cope with the sewage they generate. Less than five percent of all sewage in developing countries receives any treatment before it is discharged into the environment. In the developed world, aging treatment facilities are in urgent need of renewal and upgrading to meet new contaminant challenges and increased capacity demands from population migration from rural areas.
Conventional sewage treatment is not environmentally sustainable.We cannot continue to dump the increasing array of toxic chemicals produced by households, businesses and industries into the environment. Neither can we afford to consume the vast areas of land required for conventional sewage treatment.
Ledcor, one of Canada’s leading construction companies, is acutely aware of the need to harmonize people and their necessary economic activities, with the well-being of the planet. Ledcor is introducing alternative wastewater treatment technologies for public and private sewage treatment. One such technology is electrocoagulation (EC). For many years EC has been used to treat a broad spectrum of pollutants, but on a very limited basis due to problems with electrode fouling, flow rates and power consumption.
Nevertheless, it has been shown, in research studies, to be extremely effective at removing wastewater contaminants that biological treatment systems cannot treat.The new Ledcor system has solved the historic EC implementation problems and opens up a wide spectrum of applications for this powerful treatment process.
The Ledcor EC plant is a compact, totally enclosed, fast processing system that eliminates long retention times and land-devouring lagoons. It occupies less than 50 percent of the land required for conventional treatment plants. Its modular format permits economic tailoring to large and small communities and allows incremental expansion of systems on a gradual basis.
