The customer
SIAAP (Syndicat Interdépartemental d’Assainissement des eaux de l’Agglomération Parisienne) is the public authority responsible for wastewater treatment in the Paris region. Its main mission is to improve access to and quality of this vital resource for the entire population, and to maintain the conveyance and treatment network.
- SIAAP: 180 communes, 1800 km2, 6 plants
- Project start-up: November 2022
- Deployment at the Seine Aval plant in Achères
The challenge
In 2016, SIAAP embarked on the design of a long-term strategic plan: SIAAP 2030. It aims to implement a medium-term condition-based and predictive maintenance strategy.
Among the challenges pursued: improving the maintenance of its industrial equipment, in particular real-time monitoring and diagnosis of critical equipment, with advanced analysis techniques (IoT sensors, AI). And it was our innovative BLPredict solutions that were chosen to meet the challenge!
Our answer
The connected and intelligent maintenance experiment began in December 2022. It is being carried out on critical equipment: bar screens. Screening is a water treatment operation designed to trap materials and waste of all kinds contained in the inlet channel of a hydraulic structure or at the pre-treatment stage of domestic, agricultural or industrial wastewater, to enable them to be extracted, then stored in skips and evacuated to a treatment route.
In the first phase, BLPredict will monitor and analyze the hydraulic motor pump, its electric motor and the hydraulic system (cylinders for moving the grates). To do this, BLPredict will collect measurements of hydraulic system vibrations, motor power consumption, operating temperatures and particle levels in the oil.
Deployment
- 4 bar screens equipped with 11 sensors
- Data collected: oil (pressure, flow, temperature, level, humidity, particle counters), pump current, vibrations
- 600K+ data/day
What next?
The first few months were devoted to installing the sensors on the bar screens, which are very specific pieces of equipment as they are unique to the SIAAP treatment network. The system is currently being trained, and the first results will be available shortly.
