| description | Level-based control of the influent flow causes peak discharges at a waste
water treatment plant (WWTP) after
rainfall events. Furthermore, the capacity of the post-treatment is in
general smaller than the maximum hydraulic capacity of the WWTP. This results
in a significant bypass of the post-treatment during peak discharge. The
optimisation of influent flow reduces peak discharge, and increases the
treatment efficiency of the whole water cycle, which benefits the surface
water quality. In this paper, it is shown that half of the bypasses of the
post-treatment can be prevented by predictive control. A predictive
controller for influent flow is implemented using the
Aquasuite<span style="position:relative; bottom:0.5em; " class="text">®</span> Advanced Monitoring and Control
platform. Based on real-time measured water levels in the sewerage and both
rainfall and dry-weather flow (DWF) predictions, a discharge limitation is
determined by a volume optimisation technique. For the analysed period
(February–September 2016) results at WWTP Bennekom show that about
50 % of bypass volume can be prevented. Analysis of single rainfall
events shows that the used approach is still conservative and that the bypass
can be even further decreased by allowing discharge limitation during
precipitation. |
