Purification of Livestock Wastewater by a Constructed Wetland and Physiological Responses of Wetland Plants to Wastewater Stressors

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...

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% ...

Removal of Mercury from Wastewater Using a Constructed Wetland

Removal of mercury from municipal wastewater using a constructed wetland was studied. Wastewater, wetland plant, and sediment samples were analyzed using an advanced mercury analyzer AMA-254. Average concentrations of total mercury in inflow and outflow water were 0.157 and 0.057 μg L−1, respectively. Significant fraction of mercury (38.2 %) was removed from wastewater during pretreatment. Merc...

A Hybrid Constructed Wetland System for Decentralized Wastewater Treatment

Constructed wetland technology has been widely applied around the world to treat domestic wastewaters from the single family home to small communities. Constructed wetlands can be classified as either surface flow wetlands (similar to natural wetlands) or subsurface flow wetlands, where the wastewater flows through a media. Subsurface flow constructed wetlands can either be horizontal flow syst...
