Constructed wetland treatment system in textile industry and sustainable development.
This study focuses on the evaluation of the adequacy and sustainability of a constructed wetland (CW), with vertical flow (VF) design to treat a strongly coloured textile wastewater.Secondly an accidental AO7 overloaded discharge (700 mg l(-1)) was studied. A set of three similar VFCW beds (3x1 m2), operating in series, allowed also the efficient treatment of the AO7 heavy loaded wastewaters. The treated effluent quality enables water reuse for irrigation purposes or within the process.
