Project Background

Secondary-clarifier sludge-blanket monitoring at a 550,000 t/day benchmark plant.

Customer Challenge

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.

The TENGINE Solution

A USL intelligent sludge-blanket level meter was installed.

Implementation

USL Ultrasonic Sludge Level Analyzer.

Project Results

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.
