Design parameters affecting metals removal in horizontal constructed wetlands for domestic wastewater treatment

Wetland pollutant dynamics and control

“…All three metals were also present in the biofilm on the roots. Pedescoll et al (2015) analyzed the removal efficiency and dynamics of metals and metalloids in an experimental setup of FWS and HSSF CWs (mesocsoms) treating urban wastewater in Leon, Spain. The presence of vegetation and the flow type were the key design factors affecting system's performance.…”

Wetlands for Wastewater Treatment

“…The overall performance of CWs depends on design, With proper design considerations for the technological process, pollution load, wetland bed structure, bed filter, plants selection, and hydraulic condition of SSFCW; the flow pattern, treatment efficiency, and clogging and cost issues can be optimized (Li, . Vegetation was a key design factor affecting pollutant removal such as metals (Pedescoll et al, 2015). The roots of plants such as reeds had high capacity of accumulating and removing lead in HSSFCW (Ghannad et al, 2015).…”

“…In order to improve the removal efficiency, influential process parameters must be evaluated. Pedescoll et al (2015) determined some of the most important factors affecting the removal efficiency and dynamics of metals and metalloids. Several metals including Al, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were analyzed.…”

Seasonal Applicability of Three Plant Constructed Wetlands for Nutrient Removal in Pilot Scale

“…Wide range of wastewaters such as municipal, industrial, agricultural, and storm water can be remediated in CWs. (Pedescoll et al, 2015;Qasaimeh et al, 2015). In addition, CWs is a flexible and effective method for treating and reusing wastewater with less greenhouse gas emission (Chen et al, 2011).…”
