Effluent Compliance Monitoring
Early Warning for Total-Nitrogen Effluent Exceedance
1 / 2Project Background
Effluent total-nitrogen early warning at a county WWTP.
Customer Challenge
Industrial wastewater mixed into the influent caused large quality swings. Denitrification needed flexible control, but manual lab testing lagged — making it impossible to predict total-nitrogen exceedance or guide carbon dosing, creating an effluent-compliance risk.
The TENGINE Solution
A UV nitrate analyzer was installed.
Implementation
UVN Nitrate Nitrogen Analyzer.
Project Results
Online real-time monitoring eliminated lab lag — guiding precise carbon dosing while providing early warning of effluent total-nitrogen exceedance, avoiding compliance risk and securing stable discharge.
Related Case Studies
Plant effluent discharges directly into the Wei River. As a key river outfall, it demands extremely high data accuracy, stability and continuity. Conventional supervision lacked real-time data, making dynamic outfall control and anomaly tracing impossible; the region also faces national-section quality assessments, requiring credible, traceable online data.
A door manufacturer needed to monitor its factory discharge outlet to ensure compliance and avoid environmental violations, but lacked continuous monitoring.
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.
