The effectiveness of pollutant removal from municipal wastewater in vertical flow constructed wetlands

Municipal wastewater treatment using constructed wetlands

The aim of the paper is to present alternative to conventional (i.e., the commonly used biological treatment plants) wastewater treatment systems, appropriate for small communities and settlements. These systems are the natural treatment systems. The emphasis here is given on constructed wetlands (CWs). First, advantages and disadvantages of these systems are presented compared to conventional ...

Pollutant removal by Canna Generalis in tropical constructed wetlands for domestic wastewater treatment

Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy to grow both in water and wet land conditions. Two kinds of hybrid constructed wetlan...

Removal 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...

Nitrogen removal and sustainability of vertical flow constructed wetlands for small scale wastewater treatment

Recirculating Vertical Flow Constructed Wetlands

In parts of the United States where soils are very permeable, conventional septic tank and absorption field systems are considered the largest contributor to waterborne disease and pollution of water bodies. However, an economical, recirculating vertical flow (RVF) constructed wetland, used as a pretreatment system, can significantly improve the performance of conventional onsite wastewater tre...
