“…Nonetheless, plants uptake also plays important roles in nutrients removal in CWs (Vymazal, 2013b). Additionally, the microbial population and communities diversity around the rhizosphere and roots of plants are reported to be higher than the other regions in the wetlands (Berendsen et al, 2012;Hallin et al, 2015). Based on this consideration, the roles and evolution of the mixed-planted macrophytes in the two wetlands were further examined.…”

The outcome of competition between adjoining interspecific colonies of Phragmites and Typha in two large field pilot-scale free water surface (FWS) and subsurface flow (SSF) CWs is evaluated. According to findings, the effect of interspecific competition was notable for Phragmites australis, whereby it showed the highest growth performance in both FWS and SSF wetland. In a mixed-culture, P. australis demonstrates superiority in terms of competitive interactions for space between plants. Furthermore, the interspecific competition among planted species seemed to cause different ecological responses of plant species in the two CWs. For example, while relatively high density and shoot height determined the high aboveground dry weight of P. australis in the FWS wetland, this association was not evident in the SSF. Additionally, while plants nutrients uptake accounts for a higher proportion of the nitrogen removal in FWS, that in the SSF accounts for a higher proportion of the phosphorous removal.

“…Furthermore, Hallin et al (2015) identified denitrification as a major pathway for N-removal in sub-arctic wetlands with the evidence of denitrification genes. Li, He et al (2015) revealed the dominant nitrogen removal pathway in the tidal flow constructed wetlands was simultaneous nitrification, anammox, and denitrification process, in which the anammox 16S rRNA was the key factor of the NH4 + -N transformation rates, and (napA + narG) was the key factor regulating the NO3 --N transformation rate.…”

An update on the current research and development of the treatment technologies, which utilize natural processes or passive components in wastewater treatment, is provided in this paper. The main focus is on wetland systems and their applications in wastewater treatment (as an advanced treatment unit or decentralized system), nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds). A summary of studies involving the effects of vegetation, wetland design and modeling, hybrid and innovative systems, storm water treatment and pathogen removal is also included.

“…In northern Sweden, five plant species commonly occurring in sub-arctic wetlands were studied in nitrate-rich mine drainage to identify the relative importance of plant uptake and denitrification for N-removal (Hallin et al, 2015). Denitrification was found to be the dominating pathway for N-removal confirmed by an abundance of denitrification genes as strong indicators of plant-associated denitrification activity.…”

This review provides a snapshot of papers published in 2015 relevant to the topic of mine drainage generation and control options. The review is broken into 3 sections: Generation, Prediction and Prevention, and Treatment Options. The first section, mine drainage generation, focuses on the characterization of mine drainage and the environmental impacts. As such, it is broken into three subsections focused on microbiological characterization, physiochemical characterization, and environmental impacts. The second section of the review is divided into two subsections focused on either the prediction or prevention of acid mine drainage. The final section focuses on treatment options for mine drainage and waste sludge. The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes.
