Subsurface Flow Constructed Wetland for Wastewater Treatment

Constructed wetlands are an established treatment technology for a diverse range of polluted effluents and waters . Constructed wetland (CW) is a system engineered for treating wastewaters by using plants, soil and microorganisms; to improve the water quality. Subsurface flow constructed wetlands first emerged as a wastewater treatment technology in Western Europe based on research by Seidel in the 1960s. There are two basic types of SSF wetlands: horizontal flow (HF) and vertical flow (VF). The advantages of SSF systems include increased treatment efficiencies, fewer pest problems, reduced risk of exposing humans or wildlife to toxics, decreased waterfowl use and increased accessibility for upkeep. Subsurface-flow systems have the advantage of requiring less land area for water treatment. Thus this systems could improve effectively quality of water and wastewater
