SYSTEMATIC REVIEW ON CONSTRUCTED WETLAND FOR REMOVAL OF NUTRIENT FROM WASTE WATER

Creation of wetlands have been good constituted as impressive and sustainable liquids to the problem aquatic nutrient enrichment. They are environmentally-friendly and a biologically sustainable choice for water contamination management. The objective of the studies was to conducting systematic reviews on creation of wetland for discharge of nutrients (phosphorus and nitrogen). To point out the removal of nutrients using constructed wetland a systematized assessment of literary study was conducted. Four web page were searched with keyword from practicing a search scheme that was modified supported on the technological demand of each particular database. Out of 86 articles downloaded 10 were included the reviewed per inclusion criteria’s. The result showed that total phosphorous removed using different type of constructed wetland were 71% (SSF), 90.32% (VBF), 93.9% (HBF), 95.3% (hybrid baffle flow), 94% (constructed wetland using selected plant species) & 64% (hybrid constructed wetland). In addition to theses Ammonium Nitrogen and Total Nitrogen were significantly removed, Ammonium Nitrogen 86% (FWS), 98% (SSF), 83.9% (VBF), 92.7% (HBF), 94.7% (Hybrid Baffle Flow), 60%(Constructed Wetland with selected plant species), 83% (Hybrid Constructed Wetland), 92.8% (Constructed Wetland with selected plant species) & 88.8% (Hybrid Constructed Wetland) and total nitrogen were 95% (FWS), 98% (SSF), 56.25% (HBF), 61.67% (Hybrid Baffle Flow), 83% (Hybrid Constructed Wetland), 64.7% (Vertical flow constructed wetland with substrate CBAD, MSAS), 90.7% (Constructed Wetland with selected plant species) & 79.9% (Hybrid constructed wetland). In general the TP, TN & NH3-N, were removed significantly using different type constructed wetland.
