Wastewater treatment of combined system of biofilter and constructed wetland in arid region (Touggourt-Algeria)

Abstract

The design of wastewater treatment system is an important challenge facing the arid areas. In this paper, an integrated system is presented and tested in situ with a vertical up-flow biofilter followed by a three separated horizontal constructed wetland. This research aims to assess the water quality parameters resulting on up flow biofilter combined, with constructed wetland planted with local plant species for the removal of organic matter and nutrients pollutants from water in arid regions. The present experiment demonstrated that the wetlands planted with P. australis and T. latifolia showed the highest removal. T. latifolia performed better than P. australis for mostly parameters, while, the wetland efficiency indicated that P. australis contributed greatly to the removal of TP....
