ABSTRACT
1In order to improve the quality of smart city environment, health and well-being of their residents, the choice of a sustainable, economical and efficient technique adapted to the area conditions, becomes a necessity. To do this in Moroccan conditions, a pilot scale of Subsurface-vertical flow constructed wetland system (VFCW) was designed to treat domestic wastewater and his performance was investigated. This filter was planted by Chrosopogon zizanioides L. with a density of 4 plants/m2. Several water quality parameters including BOD5, COD, TSS, NH4+, NO3- and PO43- were monitored. The main treatment performance results showed the following average removal rates: BOD5 (79±13%), COD (80±11%), TSS (83±10%), NH4+(47±23%), PO43- (68±9%). The quality of the treated wastewaters was evaluated according to Moroccan Reject Limit Value (RLV).
