Water Treatment Plant Monitoring
Integrated Multi-Parameter Monitoring at Changchun Water Plant
Project Background
A municipal water plant in Changchun needed finished-water quality monitoring that met national standards — but had little room to spare for instrumentation.
Customer Challenge
Monitoring points at the plant were tight on space and demanded highly integrated, easy-to-install equipment. A traditional multi-instrument stack means complex wiring and heavy maintenance, and data from scattered devices is prone to inconsistency — exactly what a compliant finished-water monitoring point cannot tolerate.
The TENGINE Solution
The integrated TMS-D6000 multi-parameter water quality analyzer (DPD method) was installed, combining residual chlorine/total chlorine, turbidity, pH, ORP, conductivity and temperature measurement in a single cabinet — one device instead of six, with national-standard DPD chlorine measurement, automatic cleaning and light-source compensation.
Implementation
The integrated analyzer was wall-mounted at the finished-water monitoring point — minimal footprint, simple wiring, immediate operation.
Project Results
The plant gained highly integrated, space-saving finished-water monitoring with stable, reliable data that strictly follows national standards for municipal water plants — efficient protection of drinking-water safety for the region's residents.
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.
