Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
1) Product overview
Product Features
- BOQU’s Highly Rated COD/BOD Analyzer is a professionally designed online water-quality analyzer intended for continuous monitoring of wastewater from paper and textile processes. The product line also includes BOQU’s online heavy?metal analyzers (model references such as TCuG-3050 / TNiG-3051) and uses mature optical/colorimetric methods to deliver automated, on-site measurements with reliable performance and low operating cost.

Product Advantages
- Colorimetric/spectrophotometric measurement with chemical oxidation (e.g., ammonium persulfate digestion) and indicator-based detection (example: dimethylglyoxime for nickel).
Application Scenarios
- Typical measuring ranges (example for Ni analyzer): 0.00–2.00 mg/L and 0.10–10.00 mg/L.
- Accuracy: ≤±10% (≥0.2 mg/L) or ≤±0.02 mg/L (
- Configurable digestion/measurement cycle (minimum measurement period ~50 minutes; digestion adjustable 5–120 min), sampling interval and calibration interval adjustable.
- Outputs: 4–20 mA (two channels), RS232 and RS485; touchscreen display; data saved across power interruptions and alarms.
- Practical installation specs: indoor use recommended, ambient +5–28°C, humidity ≤90% (no condensation), AC220V power; compact cabinet (approx. H1450×W510×D450 mm).
- Low upkeep: routine maintenance typically once per month (~30 minutes).
3) Product value
- Provides continuous, automated monitoring to ensure effluent from paper and textile processes meets regulatory COD/BOD and pollutant limits, reducing compliance risk and avoiding fines.
- Early detection of process upsets and wastewater composition changes enables faster corrective action, reduces chemical and treatment costs, and improves plant operational efficiency.
- Reliable data logging and digital outputs simplify integration with SCADA/DCS and environmental reporting systems, supporting traceability and regulatory submissions.
4) Product advantages
- Engineered reliability and cost-effectiveness—designed and manufactured with selected materials and professional expertise to deliver stable long?term service.
- Flexible, configurable measurement cycles and ranges to suit different wastewater strengths encountered in paper and textile lines.
- Automatic recovery behavior (e.g., automatic discharge of residual reactants after alarms/power cycles) reduces manual intervention and downtime.
- User-friendly interface (touchscreen) and remote communication (RS232/RS485, 4–20 mA) for easy operation and integration.
- Proven export footprint and company experience: BOQU products are used domestically and internationally, indicating mature manufacturing and support.
5) Application scenarios
- Continuous online monitoring of COD/BOD and related parameters in paper mills and textile manufacturing effluent streams.
- Industrial wastewater process control (pretreatment, biological treatment, chemical dosing optimization).
- Industrial and municipal wastewater treatment plants requiring automated compliance monitoring.
- Surface water and process water monitoring where heavy-metal or organic pollution tracing is needed (with appropriate analyzer model/method).
- Environmental monitoring programs and facilities integrating real?time water-quality data into SCADA/DCS systems.
