dc.description.abstract | A wastewater treatment plant (WWTP) must be able to operate satisfactorily during critical
situations, service shutdowns and power outages. That makes the management of the
wastewater plant difficult because of disturbances that can be produce and which are difficult
to characterize and predict. The slightest failure is harmful in an environment where
performance is paramount. It is therefore necessary to ensure permanently the proper
functioning of the wastewater treatment plant toward the objectives assigned to it. To answer
this question, a Design Failure Modes and Effect Analysis (DFMEA), based on the daily
physico-chemical parameters of pollution, has been developed for the WWTP of Ain
Temouchent (treatment capacity of 10,920 m3/day) and crucial problems which penalize its
operation and limit its reliability has been identified. Preventive and corrective actions are
proposed | en_US |
