Enhanced nitrogen removal in constructed wetlands: effects
Four horizontal subsurface flow constructed wetlands (HSFCWs), named HSFCW1 (three-stage, without step-feeding), HSFCW2 (three-stage, with step-feeding), HSFCW3 (five-stage, without step-feeding) and HSFCW4 (five-stage, with step-feeding) were designed to investigate the effects of dissolved oxygen (DO) and step-feeding on nitrogen removal. High removal of 90.9% COD, 99.1% ammonium nitrogen and...
متن کاملRemoval processes for arsenic in constructed wetlands.
Arsenic pollution in aquatic environments is a worldwide concern due to its toxicity and chronic effects on human health. This concern has generated increasing interest in the use of different treatment technologies to remove arsenic from contaminated water. Constructed wetlands are a cost-effective natural system successfully used for removing various pollutants, and they have shown capability...
متن کاملRemoval Mechanisms in Constructed Wastewater Wetlands
The use of constructed wetlands is a relatively new technology but the system is gaining popularity due to its low tech system for treating wastewater (DeBusk, 1999b).Constructed wetlands have found to be effective in treating domestic wastewater where municipalities are concerned with reducing suspended solids, organic matter, phosphorus, nitrogen, and pathogens. Constructed wetlands mimic nat...
متن کاملFactors Controlling Biogeochemical Removal of Nitrogen in Constructed Wetlands
The Long Island Sound (LIS) estuary is affected by summer hypoxia as a result of high nitrogen loads from New York and Connecticut watersheds. In order to mitigate hypoxia, managers have established a goal of reducing the nitrogen load from nonpoint sources by 10%. One strategy to reduce N loads from nonpoint sources is the use of constructed wetlands, which provide an ecosystem service by remo...
متن کاملThe persistence and removal of enteric pathogens in constructed wetlands.
Sedimentation is thought to be one of the mechanisms of microbial reduction from wetlands used for wastewater treatment. This study compared the occurrence and survival of enteric indicator microorganisms and pathogens in the water column and sediments of two constructed surface flow wetlands in Arizona. On a volume/wet weight basis the concentration of fecal coliforms and coliphage in the wate...
