Industrial Effluent Compliance
Discharge-Outlet Monitoring for a Door Manufacturer in Baoding
1 / 2Project Background
Ningdu Jiu'an Door Industry in Baoding treats its factory wastewater on site and must monitor COD and ammonia nitrogen at the discharge outlet — with readings visible on the spot for the plant's own environmental records.
Customer Challenge
The monitoring point sits inside the factory building, so continuous, stable power supply had to be secured; the data needed to be displayed locally so staff could keep regular manual records; and the sampling had to represent the true discharge condition.
The TENGINE Solution
A UV-method COD and ammonia-nitrogen analyzer was installed at the treated-water discharge outlet. With 220V power secured inside the plant building, the analyzer runs continuously; readings are shown on a local display transmitter, making weekly manual record-keeping straightforward.
Implementation
The analyzer was installed at the discharge outlet inside the plant with guaranteed power supply and local data display for routine records.
Project Results
COD and ammonia nitrogen at the outlet are now monitored online around the clock, with on-site display supporting the plant's routine environmental records — reliable data for the enterprise's discharge compliance.
Related Case Studies
The end customer's facility had no online water-quality monitoring at all — only manual spot checks — leaving wastewater indicators unsupervised between samples, failing the new regulatory requirement for online installation, and exposing the operator to environmental penalties.
