الملخص EN

A level of water quality intended for human consumption does not seem necessary for domestic uses such as irrigation of green spaces.

Alternative water supplies like the use of greywater (GW) can thus be considered.

However, GW contains pathogenic microorganisms and organic compounds which can cause environmental and health risks.

As the risks related to recycling are unknown, GW treatment is necessary before reusing.

To describe the risks related to GW reuses, the scientific approach performed in this study was to characterize domestic GW in order to select an appropriate treatment.

The biotechnology chosen is a Horizontal sub-surface flow constructed wetland reactor.

In order to minimize health risks, an optimization step based on UV disinfection was performed.

The treatment performances were then determined.

The treated GW produced in this study reached the threshold values expected by the Moroccan regulation for irrigation of green spaces with treated wastewater.

Indeed, the COD and the TSS obtained in treated GW without disinfection are respectively 16.6 mg O2 L1 and 0.40 mg L1 .

The horizontal sub-surface flow constructed wetland (HSSF CW) reactor has been used to treat 1.2 m3 /d of GW for 100 days.

Three lawn plots have been irrigated respectively with raw GW, treated GW and tap water as a reference.

Contrary to the lawn plot irrigated with raw GW, the risk analysis performed in this study has shown no significant difference between the law plots irrigated with treated GW combined with UV disinfection and the one irrigated with tap water.

Overall, UV disinfection treated GW produced from the HSSF CW reactor developed in this experiment is thought to be an effective and feasible alternative for agricultural reuse.
