Microbial biomass, activity and community composition in constructed wetlands

Comparative study of microbial community structure in different filter media of constructed wetland

“…The elimination of easily degradable organic wastewater compounds, as well as nitrogen and phosphorus processes, is a consequence of a combination of chemical, physical and biological processes (Truu et al, 2009). Zhang (2007 has studied the treatment performances of eight media.…”

Removal of antibiotics and antibiotic resistance genes from domestic sewage by constructed wetlands: Optimization of wetland substrates and hydraulic loading

“…Constructed wetlands (CWs) are artificial wetlands which are designed and constructed to manipulate the natural processes to treat wastewater, and can be classified into surface flow and subsurface flow wetlands (vertical or horizontal) according to their hydrology and flow path (Ji et al, 2002;Truu et al, 2009;Vymazal, 2010;Zhi and Ji, 2012). Compared to conventional wastewater treatment technologies, CWs have economical and eco-friendly advantages due to their low-cost, easy operation and low maintenance (Puigagut et al, 2008;Faulwetter et al, 2009).…”

Performance assessment and microbial diversity of two pilot scale multi-stage sub-surface flow constructed wetland systems

“…However, their designs are generally based on information about chemical and physical parameters with only a limited number of studies such as Calheiros et al (2009) and Truu et al (2009) focusing on the composition of the microbial communities in these systems. Consequently, while the design of these systems has evolved, the increased knowledge acquired by engineers has not been accompanied by an equivalent growth in understanding of the microbial ecology of these systems.…”
