Water Treatment Plant Monitoring
Distributed Monitoring Scheme at Baise Water Plant
Project Background
Baise's municipal water plant needed finished-water monitoring tailored to its site — with the freedom to combine parameters as conditions required.
Customer Challenge
Site conditions demanded flexible parameter selection rather than a fixed all-in-one device: integrated units come with fixed parameter sets and poor adaptability, and outdoor equipment is exposed to dust and environmental interference.
The TENGINE Solution
A distributed scheme was deployed: separate MTU turbidity, pH, FCL free chlorine, CLD chlorine dioxide and conductivity instruments — covering residual chlorine, chlorine dioxide, turbidity, pH, ORP, conductivity and temperature — combined in an outdoor micro-cabinet of just 0.4 m² footprint on a mobile wheeled base, with strong ingress protection against the elements.
Implementation
The distributed instruments were mounted in the compact outdoor cabinet with sampling, data transmission, analysis and power supply integrated — deployable exactly where the site allowed.
Project Results
Monitoring is now configured to the plant's actual needs, shielded from outdoor interference, delivering precise and stable data that meets national standards — protecting residents' drinking water while cutting equipment and maintenance costs.
Related Case Studies
The plant's raw water comes from an upstream reservoir whose quality swings constantly: sediment wash-in from rainstorms, summer algae blooms and organic-matter spikes, drought-period changes. Worse, by the time abnormal water reached the plant intake and was detected, several hours had already passed — the best window for response was gone.
The upgraded plant demanded high accuracy on difficult measurements — low-turbidity drinking water and residual chlorine among them — with instruments that integrate stably into the plant's automation system. Site conditions threw up real problems too, such as abnormal inlet flow conditions, and the schedule required fast technical response and on-site problem solving.
A surface water plant has many treatment stages, and running them on operator experience alone leaves blind spots: filter backwash timing, sedimentation-basin sludge discharge and disinfectant dosing could not be adjusted dynamically against actual water conditions, risking off-spec finished water.
