Abstract

Since 2012, Moroccan kingdom had established new laws concerning the regulation of the
waste water quality that should require certain qualifications to be thrown to nature. The problem was that by
making the choice of having an anaerobic treatment trough an UASB (for Upflow Anaerobic Sludge Blanket)
to get rid of the pollution we were confronted to an important sensitivity related to the dosing of the different
reagents made to regulate the nutrition of the anaerobic cultures which ensure the pollution degradation. This
paper was made to reduce the gap between the doses of reagents that are injected in every stage of the
treatment and the doses that should be injected to insure the environmental requirement at the output of the
station by considering the HRT “hydraulic retention time” and the large variability of the waste water
composition that heads to the station, normally we can’t rely on the analyses made at the output of the
treatment to adjust the doses that’s why we chose to combine the analyses made at the input of the treatment
with the ratios mentioned earlier to find a way to adjust the doses to avoid an excessive injection or a lack of
nutriment that may reduce the effectiveness of the treatment. This way, it will be economically and
environmentally optimized to correct the doses just in time according to the input composition of the waste
water.
