Microorganisms play a vital role in degradation of multiple pollutants in constructed wetlands
(CWs). Thus, the search for methods to improve microbial degradation in CWs is crucial …

Dissolved oxygen (DO) is one of the most important factors that can influence pollutants
removal in constructed wetlands (CWs). However, problems of insufficient oxygen supply …

Subsurface oxygen availability tends to be one of the main rate-limiting factors for removal of
carbonaceous and nitrogenous compounds in subsurface flow (SSF) wetlands used for …

Vermifiltration is an economically affordable and environmentally sustainable technology for
treatment of wastewater. However, the long-term effective performance and field scale …

The performance, effluent quality, land area requirement, investment and operation costs of
a full-scale waste stabilization pond (WSP) and a pilot scale horizontal subsurface flow …

Reactive-transport models have been widely used to describe biogeochemical processes in
subsurface environments. Horizontal subsurface-flow constructed wetlands fall in that …

Constructed Wetlands (CW) are a suite of natural wastewater treatment systems that are
governed by biological, chemical and physical processes. These processes, in tandem …

Bacteria communities growing in constructed wetlands play a major role on the removal of
pollutants from wastewater and the presence of a stable community is a critical factor …

Process-based models are useful for comprehending constructed wetland (CW) internal
dynamics and function, as well as optimizing CW design and operation. Over the last two …

Simulation and performance results of a saturated vertical up-flow constructed wetland (SVU
CW) operated under different operational conditions are presented. The SVU CW consists of …
