Effect of Nighttime Drainage Operation on Nitrogen Removal in Wastewater Treatment Plant of Subsurface Flow-Constructed Wetland with Zeolite Substratum

Nitrogen removal from wastewater by an aerated subsurface-flow constructed wetland in cold climates.

The objective of this study was to assess the role of cyclic aeration, vegetation, and temperature on nitrogen removal by subsurface-flow engineered wetlands. Aeration was shown to enhance total nitrogen and ammonia removal and to enhance removal of carbonaceous biochemical oxygen demand, chemical oxygen demand, and phosphorus. Effluent ammonia and total nitrogen concentrations were significant...

Wastewater Treatment Using Horizontal Subsurface Flow Constructed Wetland

The last few decades witnessed sharp focus on environment pollution and its impact on life in nature. Wetlands can be used for biological treatment of wastewater. Problem statement: Scarcity of water is considered as a global problem and Iran is one the countries which is facing water shortage problem. Pollution of water bodies restrict the availability of water for various uses. Treatment of w...

Wastewater Treatment with Vertical Flow Constructed Wetland

Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...

Subsurface Flow Constructed Wetlands for Wastewater Treatment

Nitrogen 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% ...
