WWTP stations with Membrane Bioreactor technology require continuous monitoring of their operating parameters. The Bridgemeter allowed a significant increase in production and efficiency.
DECENTRALIZED OPERATION MODEL
- MBR treatment plants require constant management due to the nature of the membrane fouling process
- Decentralized operation over significant distances
- Requirement of 1 operator per operating station
- Supervision and engineering vehicle for every 3 stations
- Timely data collection from the engineering team
- Difficulty visualizing the operation
- Inconsistency in production level
- Constant unscheduled stops
- Production reports for SLA
Solution: IIOT Industrial
EVERY OPERATION IS MONITORED IN REAL TIME
The monitoring system records and sends notifications to the operators responsible for the necessary measures and cycle corrections. The water meter measurement report reflects the reduction or increase in treated water productivity on a daily basis.
With information from the manufacturer, intelligent cross conditions were created so that the system could interpolate the crossing of several parameters to replace sensors that did not exist on the market. As an example, the intersection of pump current measurement and transmembrane pressure (TMP), the system learns and warns bands corresponding to: Clean Membrane, Partially Encrusted Membrane and Encrusted Membrane. The maximum allowable pressure is also constantly monitored
All PLC parameters are also monitored.
Results
EVERY OPERATION IS MONITORED IN REAL TIME
- Average increase of 30% in production
- 27% reduction in unscheduled stops
- Permanence of TMP pressure in 95% of measurements
- Daily record for ETE production after using the system
- Reduction of team and operating infrastructure by 40%
- Issuance of automatic production and SLA reports
- Monitoring presence team supervision.
The monitoring brought an unprecedented view of the effluent treatment plant, as previously there was only a “photo” of visits carried out by the operator. With the Industrial IoT system, it was possible to create a “film” with live transmission of the readings taken during the treatment process and intelligence of alarms and notifications. Particularly in industry, even minimal increases in productivity are capable of generating significant improvements in results with very low implementation costs, like the one in this case.
