AN EFFICIENT APPROACH TO MANAGE DOMESTIC WASTEWATER IN SMART CITY

Taouraout, A.; Chahlaoui, A.; Belghyti, D.; Taha, I.; Lachhab, M.

The adoption of an ecological sanitation system, meeting the requirements hygienic and sanitary, constitutes a feasible and technically and economically acceptable solution in the future smart city. This new sanitation concept has the advantage of solving the problems of pathogens of human waste at source, thus offering the possibility of reusing them after treatment (recycling) in order to improve the standard of living of the population and protect the environment. The aim of this study is to evaluate the efficiency of a vertical Multi-Soil-Layering system (MSL) system to treat domestic wastewater under three hydraulic loading rates: 250 L/m 2/day, 350 L/m 2/day and 500 L/m 2/day, in Moroccan conditions. To do this, a vertical MSL system measuring 20cm × 60cm × 78cm (L × W × H) was designed to treat domestic wastewater and his performance was investigated. The results showed high removal of organic matters and nutrients under the three hydraulic loads tested; the performance averages recorded are upper than 84 % for organic matters, 83.1 ± 7.2 % for ammonium and 72.4 ± 14.1 % for orthophosphate. The quality of the treated wastewater was evaluated according to Moroccan reject limit value. Consequently, this system could be considered an effective solution to be adopted for decentralized domestic wastewater treatment in Moroccan conditions.
