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 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...
متن کاملCyanobacterial Nitrogen Fixation (CYANOFIX)
The European Science Foundation acts as a catalyst for the development of science by bringing together leading scientists and funding agencies to debate, plan and implement pan-European initiatives. This ESF programme builds on the longstanding European research tradition in cyanobacterial nitrogen fixation. It is, however, the first coordinated European interdisciplinary programme in the field...
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 کاملNitrogen Removal in a Horizontal Subsurface Flow Constructed Wetland Estimated Using the First-Order Kinetic Model
We monitored the water quality and hydrological conditions of a horizontal subsurface constructed wetland (HSSF-CW) in Beijing, China, for two years. We simulated the area-based constant and the temperature coefficient with the first-order kinetic model. We examined the relationships between the nitrogen (N) removal rate, N load, seasonal variations in the N removal rate, and environmental fact...
