Constructed wetlands (CW) are treatment systems that use natural processes involving wetland vegetation, soils and their associated microbial assemblages to improve water quality i.e. treating municipal or industrial wastewater, grey-water or storm-water runoff.
A free-water surface constructed wetland (FWS_CW) is a series of flooded planted channels or basins.
How? → ● As water slowly flows through the wetland, particles settle, pathogens are destroyed, and organisms and plants utilize the nutrients. Pre-treating of wastewater in e.g. a septic tank is necessary to avoid excess accumulation of solids and garbage. ●Plants grown on the wetland may be used for composting or as biomass for energy production whereas the effluent can be used for aquaculture and irrigation
Where? → FWS_CW is commonly used as an advanced treatment after secondary or tertiary treatment processes. Appropriate for small sections of urban areas (e.g. decentralised treatment for a community) and for peri-urban and rural communities Risk of mosquito breeding if not properly designed.
