Biological processes are used to treat wastewater through anaerobic and aerobic digestion processes of micro organisms. These naturally break down and absorb the organic matter carried in wastewater to produce biogas, heat and compost.
Biological processes are used to treat sewage, sludge, municipal and industrial wastewater. WaterIcon also uses biological process to treat aquariums and fish ponds.
Treatment enables impure water to be re-used and improves the quality of effluent being released into the environment. This allows municipalities and industries to save on compliance and water costs, while at the same time encouraging the development of a healthy, efficient biomass.
Biological water treatment re-use
Anaerobic digestion works to ferment sludge at raised temperatures and generates biogas with a high proportion of methane. These gases may be recycled for use in heating processes required by the manufacturer or used to run engines and microturbines.
Both anaerobic and aerobic digestion processes can sufficiently destroy disease-causing microorganisms and parasites to allow the resulting digested solids to be safely applied to land as compost or a fertilizer, provided that levels of toxic constituents are sufficiently low.
