Wastewater Technology Fact Sheet Wetlands: Subsurface Flow DESCRIPTION Wetland systems are typically described in terms of the position of the water surface and/or the type of vegetation grown. Most natural wetlands are free water surface systems where the water surface is exposed to the atmosphere; these include bogs

4 Design Horizontal Subsurface Flow Constructed Wetland 4.1 Design HSSF using design model acc. Njau Since the first order rate constant is dependent on the velocity of the wastewater in the system, a long, narrow wetland will guarantee the best result.
Louisiana, over 30,000 ln ft of horizontal wells were installed for a pump-and-treat hydraulic control system to operate while plant operations continued. • Horizontal wells are especially cost effective at low-permeability sites where numerous vertical wells would be required. For example, at Williams Air Force Base in AZ, the deepest horizontal
The main objective of this study was to evaluate the performance and treatment efficiency of the Horizontal Sub-Surface Flow Constructed Wetland treatment system (HSF-CW) in an arid climate. Seventeen sub-surface, horizontal-flow HSF-CW units have been operated for approximately three years to improve the quality of partially-treated municipal wastewater.

Apr 27, 2018· The horizontal subsurface flow constructed wetland is a good option where land is cheap and available. Depending on the volume of the water and the corresponding area requirement of the wetland, it can be appropriate for small sections of urban areas, as well as for peri-urban and rural communities. It can also be designed for single s.
horizontal subsurface-flow wetland can reduce levels of faecal micro-organisms by over 99%, it will not produce a fully disinfected effluent. The outflow from the wetland still represents a potential health hazard and must be properly managed.
Horizontal subsurface flow (HSSF) constructed wetlands are widely used for wastewater treatment but there’s still a lack of information on flow characteristics changes throughout the porous bed over time. The continuous growth of roots, the adsorption, sedimentation and precipitation of wastewater compounds and the biofilm release over ...
A monitoring campaign in a horizontal subsurface flow constructed wetland under the influence of transient loads of flow-rate, organic matter, nitrogen and suspended solids showed an irregular removal of COD and TSS and lower both removal

The vertical flow constructed wetland is a good treatment for communities that have primary treatment (e.g., Septic Tanks, S.9), but are looking to achieve a higher quality effluent. Because of the mechanical dosing system, this technology is most appropriate where trained maintenance staff, constant power supply, and spare parts are available.

Constructed Wetlands with Horizontal Subsurface Flow HF CWs consist of gravel or rock beds sealed by an impermeable layer and planted with wetland vegetation (Figure 5). The wastewater is fed at the inlet and flows through the porous medium under the surface of the bed in a more or less horizontal path until it reaches the outlet zone, where it is
Apr 27, 2018· A horizontal subsurface flow constructed wetland (horizontal subsurface flow CW) is a large gravel and sand-filled basin that is planted with wetland vegetation.It is used for secondary or tertiary treatment of wastewater (e.g. greywater or blackwater).
Horizontal subsurface flow constructed wetlands (SSFCWs) are being used worldwide to treat wastewater from a variety of sources. An extensive literature review was conducted to update the current state of scientific knowledge on the performance of SSFCWs for domestic wastewater treatment.
