EVALUATION OF THE PHYSICOCHEMICAL QUALITY OF RAW AND TREATED WASTEWATER IN THE CITY N’GOUSSA AND THE POSSIBILITY OF THEIRA. Journal of Fundamental and sciences. vol.10, no 2. May 2018.

The physicochemical results obtained revealed that the raw wastewater entering the treatment plant exhibits fairly high organic and nitrogen pollution. Removal of MES and nitrogen compounds appears inefficient due to the massive proliferation of implanted filters.enwastewater treatment; Reed plant filter; arid environment; physico-chemical parameters; Abatement rateArticle
