Project Background

Guye wastewater treatment plant in Tangshan is a combined municipal and industrial facility treating 10,000 m³/day — with influent mixed from nine enterprises across coal mining, iron & steel, coking and chemicals. Its AAO biological process depends heavily on dissolved-oxygen, sludge and water-quality data.

Customer Challenge

The mixed industrial influent is complex and swings hard; the AAO process demands close tracking of DO, sludge concentration and quality parameters; and with monitoring points spread across the whole plant, a single instrument type could never fit every location. Data lag or loss directly threatens process stability and effluent compliance.

The TENGINE Solution

TENGINE supplied 83 instruments across 13 product types covering the whole process: online COD, ammonia nitrogen, total phosphorus and total nitrogen analyzers; MLSS suspended-solids meters; LDO luminescent dissolved oxygen; pH and ORP analyzers; TUL ultrasonic level meters; TSS turbidity; DPH digital pH; TRC residual chlorine; and USL ultrasonic sludge blanket meters — installed as pole-mounted split units, pipe-wall mounts and centralized indoor cabinets to fit each location.

Implementation

The 83 instruments were deployed across the influent, AAO biological tanks, treatment units and effluent, with all data flowing into the plant's automation system in real time.

Project Results

The plant now runs its AAO process on complete, real-time data: influent quality shocks from the nine industrial dischargers are seen as they arrive, biological conditions are kept in range, and effluent stays compliant — a proven template for complex industrial-park wastewater monitoring.

Full-Line Online Monitoring of Paper-Mill Wastewater in Vietnam

The mill had long relied on imported instrument brands: procurement, system deployment and O&M costs were all high, and a mixed-brand fleet brought poor compatibility, fragmented after-sales and inefficient maintenance. It needed a single accountable supplier without giving up measurement performance.

Tofu production is water-intensive, and process water can carry contaminants such as heavy metals and organic pollutants. Without continuous monitoring, quality risks to the product — and health risks to consumers — can go undetected. At the same time, improperly managed wastewater discharge harms the environment and exposes the company to regulatory violations and legal liability.

Industrial and domestic inflows mix with wide quality swings, while the PPP contract demands accurate effluent quantity for operational settlement and discharge control. Instruments had to resist interference and run stably for years.
