Case Studies
Real Projects, Real Evidence
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.
A surface-water treatment plant must control quality across the full process — from raw-water intake through sedimentation and filtration to finished water — where conditions vary stage by stage and single-point checks are insufficient.
High-rise residences depend on secondary water supply, where tank and pump conditions directly affect tap-water quality; this benchmark project required dependable, continuous monitoring and a presentable, replicable setup.
Sunrise Tofu in Canada needed reliable water-quality monitoring for its food-processing operation to maintain product quality and meet local requirements.
The site had no online water-quality monitoring at all — only manual grab sampling — so discharge indicators could not be tracked continuously. Vietnam's new environmental regulations mandate online monitoring installations at pollution sources, and the customer faced administrative penalty risk without compliant, always-on data.
The Xiao Taihou River in Chaoyang needed compact water-quality early warning to support river management within a dense urban district.
