The Significant Variables of Effluent Constructed Wetlands Treated Domestic Wastewater by Statistical Tests

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...

Localized domestic wastewater treatment: part I - constructed wetlands (an overview)

Constructed wetlands (CW) are an alternative localized treatment technology suitable for reducing BOD, COD, NPK and pathogens to acceptable levels for subsequent use of treated water, especially for irrigation. Dissolved chemicals and heavy metals are also reduced to an extent. CWs are extensively used in developed countries for secondary and tertiary treatment of domestic sewage and treatment ...

Constructed Wetlands for Wastewater Treatment

Assessment of diesel-contaminated domestic wastewater treated by constructed wetlands for irrigation of chillies grown in a greenhouse

In order to avoid environmental pollution and eliminate the need for using fertiliser, this study assessed for the first time the optimum performance of mature (in operation since 2011) vertical flow constructed wetlands in treating domestic wastewater (with and without hydrocarbon) and the subsequent recycling of the outflow to irrigate chillies (De Cayenne; Capsicum annuum (Linnaeus) Longum G...

Fate of physical, chemical, and microbial contaminants in domestic wastewater following treatment by small constructed wetlands.

In order to evaluate the efficacy of constructed wetlands for treatment of domestic wastewater for small communities located in rural areas, small-scale wetland mesocosms (400 L each) containing two treatment designs (a mixture of Typha, Scirpus, and Juncus species; control without vegetation) were planted into two depths (45 or 60 cm) with pea gravel. Each mesocosm received 19 L/day of primary...
