Water Treatment Plant Monitoring
Full-Process Monitoring Upgrade at Fuhe Reservoir Central Water Plant
1 / 4Project Background
The Fuhe Reservoir central water plant in Tuanfeng County, Huanggang underwent a standards-upgrade renovation, expanding supply to more than 120,000 people across four townships — and requiring online monitoring across the entire surface-water treatment process.
Customer Challenge
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.
The TENGINE Solution
TENGINE deployed a complete multi-parameter package at the distribution well and outlet pump house: the MTU high-precision turbidity analyzer (with bubble elimination, accurately reading below 0.1 NTU), pH, TSS turbidity, DPD residual chlorine analyzer (national-standard DPD spectrophotometry), integrated level meter and electromagnetic flowmeter — full-dimensional data acquisition across the treatment process.
Implementation
During commissioning, the chlorine analyzer's inlet flow ran low; TENGINE's service system responded within 0.5 hours, produced a rectification plan within 12 hours and was on site within 24 — adding a booster pump that restored normal measurement. All data now feeds stably into the plant's automation system.
Project Results
Every treatment stage is now monitored online in real time, giving the automation system a solid data foundation. The standards-upgrade project landed successfully, securing safe supply for 123,000 people in four townships while raising operating efficiency and cutting O&M cost.
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.
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.
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.
