The problem was that by<br>making the choice of having an anaerobic treatment trough an UASB (for Upflow Anaerobic Sludge Blanket)<br>to get rid of the pollution we were confronted to an important sensitivity related to the dosing of the different<br>reagents made to regulate the nutrition of the anaerobic cultures which ensure the pollution degradation. This<br>paper was made to reduce the gap between the doses of reagents that are injected in every stage of the<br>treatment and the doses that should be injected to insure the environmental requirement at the output of the<br>station by considering the HRT “hydraulic retention time” and the large variability of the waste water<br>composition that heads to the station, normally we can’t rely on the analyses made at the output of the<br>treatment to adjust the doses that’s why we chose to combine the analyses made at the input of the treatment<br>with the ratios mentioned earlier to find a way to adjust the doses to avoid an excessive injection or a lack of<br>nutriment that may reduce the effectiveness of the treatment. This way, it will be economically and<br>environmentally optimized to correct the doses just in time according to the input composition of the waste<br>water.<br><br></p>}, number={20}, journal={GEOMATE Journal}, author={Tkiouat Chafiq}, year={2017}, month={Apr.}, pages={1751–1755} }
