WHAT IS A WETLAND ALSO KNOWN AS REED BEDS? WETLAND Although the subsurface environment of a Wetland is largely devoid of oxygen, tiny oxygen rich micro-sites exist adjacent to the macrophyts roots. In traveling through the sequence of oxygen-rich and oxygen-poor environments provided by the Wetland, wastewater is subjected to conditions which enhance the removal of a number of important pollutants such as organic carbon (which depletes dissolved oxygen) in aquatic ecosystems and is hence referred to as Biochemical Oxygen Demand (BOD) and nitrogen (which can cause algal blooms in surface waters). Other pollutants removal mechanisms in Wetlands include filtration, sedimentation and plant uptake of nutrients. Wetlands also have the capacity to lower the concentrations of disease causing pathogens from wastewater. When is a WETLAND applicable? The choice of secondary treatment technology will be governed by a number of factors including: |
