Subsurface Flow Constructed Wetlands for Wastewater Treatment

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...

Treatment Efficiencies of the Vertical Flow Pilot-Scale Constructed Wetlands for Domestic Wastewater Treatment

To foster the practical development of the constructed wetlands used for water quality enhancement in Turkey, 2 vertical subsurface flow pilot-scale constructed wetlands were implemented on the METU campus, Ankara, Turkey. Both of the wetlands were planted with Phragmites australis and operated identically at a flowrate of 3 m3.d−1 and a hydraulic loading rate (HLR) of 0.100 m.d−1, intermittent...

Removal of total suspended solids from wastewater in constructed horizontal flow subsurface wetlands.

Subsurface horizontal flow experimental wetlands (reed beds), were designed and built based on a combination of two design methodologies, that of the WRc and Severn Trent Water plc (1996) and that of the USA, EPA (1988). Four different growing media were used with a combination of top soil, gravel, river sand, and mature sewage sludge compost, to determine the best substrate for total suspended...

Design of horizontal and vertical subsurface flow constructed wetlands treating industrial wastewater

Constructed wetlands have become a good alternative to urban and industrial wastewater treatments. Because of the many interactions between the different parts that form the wetland, the design of these systems used to be very complex so a good design tool is required. Hybrid constructed wetlands mix the aerobic and anaerobic properties of vertical and horizontal subsurface flow constructed wet...
