Secondary-clarifier sludge-blanket monitoring at a 550,000 t/day benchmark plant.
Thách thức của khách hàng
This benchmark South China plant treats 550,000 tons/day. Secondary-clarifier sludge level is critical to scraper control, effluent compliance and energy saving — but turbulent water, sludge adhesion and complex sludge-water interfaces make measurement hard. Conventional ultrasonic interface meters suffer from scum and bubbles, producing unreliable data that cannot drive automated scraper control.
Giải pháp của TENGINE
A USL intelligent sludge-blanket level meter was installed.
Triển khai thực hiện
USL Ultrasonic Sludge Level Analyzer.
Kết quả dự án
Accurate, stable level data now drives smart scraper control, eliminating idle running and saving energy. The self-cleaning design drastically reduces maintenance, solved the industry's secondary-clarifier interface challenge, and proved domestic interface meters in large municipal plants.

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.
