Geo Physicochemical Properties for Soil Base Subsurface Constructed Wetland System

Wetland land system is the natural way for the treatment of wastewater. Constructed wetland system (CWs) is a traditional way for treatment. CWs are considered as secondary or tertiary treatment systems. CWs provide good landscape and better habitat quality for the community. Various types of media are used in Constructed Wetland Systems. Literature shows that various soils have the potential to filtration medium (in substratum) in Horizontal Flow Subsurface Constructed Wetland System (HFSCWs) for wastewater treatment. Soil should have few environmental and geo tech properties. Soil provides the root zone in rhizome network for the vegetation in CWs. Soil provides the absorbent media not only in the HFSCWs but Vertical Flow Constructed Wetland system (VFCWs) also. As per Environmental Protection Agency (EPA), various properties of filter media were described. This review base on types of commonly used wetland, filter media, plant use and geo physicochemical parameters of filter media.
