Rural & Township Wastewater
Monitoring for 22 Village & Township Wastewater Plants
Project Background
Full-process monitoring across 22 dispersed village & township plants.
Customer Challenge
22 village & township plants are numerous and dispersed. The A2O+MBR process demands high monitoring of bioreactor sludge concentration, DO, pH, product flow and aeration volume. Large numbers of reliable online instruments were needed for process control, effluent metering and precise aeration control.
The TENGINE Solution
965 instruments across 10 types: MLSS suspended-solids meter, LDO optical dissolved oxygen, pH meter, ultrasonic open-channel flowmeter, electromagnetic flowmeter, thermal gas mass flowmeter, and more.
Implementation
MLSS Suspended Solids (Sludge) Concentration Analyzer, LDO Luminescent Dissolved Oxygen Analyzer, TPH pH Analyzer, TUF Ultrasonic Open-Channel Flowmeter, TLD Electromagnetic Flowmeter, TMF Thermal Gas Flowmeter.
Project Results
Full-process online monitoring provides reliable data for A2O+MBR control — aiding aeration energy saving and sludge management. The batch deployment across 22 dispersed plants secures stable compliance and supports village & town water-environment governance.
Related Case Studies
The plant handles a large daily flow through a complex multi-stage process, requiring precise control of influent/effluent quality and process status. Water quality data must also feed the environmental regulator's system, but legacy single-parameter instruments with lagging data could not support full-process control or compliant reporting.
Municipal wastewater plants present complex conditions and fluctuating water quality. Instruments run continuously while submerged, so conventional meters age, drift and fail — driving up replacement and maintenance costs and conflicting with the need for long-term, low-maintenance operation.
Aging online instruments no longer met current pollution-source monitoring specifications. The project had a tight schedule and complex construction, requiring on-time delivery of a large instrument batch; multiple dispersed sites demanded certified, stable devices connected to a smart-water platform, plus complete installation and commissioning services.
