The enhancement of water quality by constructed wetland systems is increasingly practiced world wide. The use of a treatment train consisting of an up-flow anaerobic sludge blanket (USAB)... a treatment train consisting of an up-flow anaerobic sludge blanket (USAB) reactor followed by free water surface and subsurface flow constructed wetlands in series has been investigated. The common macrophyte in Egypt Typha latofolia (cattail) was used in both wetland units at a planting density o ...
