Nitrogen removal in constructed wetland systems
Since the mid 1990s, constructed wetlands have been increasingly used as a lowenergy ‘green’ technique, in the treatment of wastewater and stormwater, driven by the rising cost of fossil fuels and increasing concern about climate change. Among various applications of these wetlands, a significant area is the removal of nitrogenous pollutants to protect the water environment and to enable effect...
متن کاملNitrogen removal from industrial wastewater by hybrid constructed wetland systems
The efficiency in nitrogen removal from wastewater generated at CSBP Ltd fertiliser and chemical manufacturer by two hybrid constructed wetland mesocosms was compared. The mesocosms were set up in order to help clarify the reasons why the two year old constructed wetland located at the industrial facility, a 1.2 ha free water surface/vertical flow conjugated system, has performed under the 50% ...
متن کاملRemoval of Pharmaceutical Products in a Constructed Wetland
Background: There is growing interest in the natural and constructed wetlands for wastewater treatment. While nutrient removal in wetlands has been extensively investigated, information regarding the degradation of the pharmaceuticals and personal care products (PPCPs) has only recently been emerging. PPCPs are widely distributed in urban wastewaters and can be removed to some extent by the con...
متن کاملConstructed Wetland Treatment of Nitrates: Removal Effectiveness and Cost Efficiency
A constructed wetland (CW) was strategically placed to treat nitrates in groundwater as part of a watershed-based farmer engagement process. Using stream water quality data collected before and after installation, this CW was found to reduce stream concentrations of nitrogen from nitrate (NO3-N) during the growing season by about 0.14 mg/l at mean streamflow, a 17% reduction. Based upon realist...
متن کاملExamining the Inter-Storm Variability in Nitrogen Removal Efficiency in a Connecticut Constructed Wetland
Suburban stormwater runoff carries large amounts of nitrogen and other pollutants from fertilized lawns, septic systems, and atmospheric deposition, ultimately contributing to hypoxia (low dissolved oxygen levels) in Long Island Sound and severely perturbing aquatic life. Managers of Long Island Sound have set a goal of achieving a 10% reduction in nitrogen from nonpoint sources in order to mit...
