Chemical Oxygen Demand Analyzer - for Potable Water - BOQU

Product Overview

1) Product overview

Product Features

- BOQU’s Chemical Oxygen Demand (COD) analyzer for potable water is an online/automatic water-quality instrument designed for continuous, reliable monitoring of key water quality parameters. BOQU applies strict international-quality production controls and leverages its instrument-development experience (for example, the company’s NHNG-3010 ammonia?nitrogen online meter) to deliver robust, factory-tested analyzers suitable for treatment plants, distribution systems and environmental monitoring.

Product Advantages

- Advanced flow-injection / automated analysis technology for stable, repeatable measurements.

Application Scenarios

- Automatic enrichment and wide measuring capability to handle both very low and very high concentrations without frequent manual adjustments.

- Safe, low-toxicity reagents and simple reagent preparation to reduce handling hazards and operating cost.

- Patented gas–liquid separation design that eliminates complex sample pretreatment and reduces the need for cleaning/maintenance.

- Automated functions: automatic sampling, calibration, residual-reactant purge after power-up/alarms, and touchscreen control with data logging.

- Standard industrial outputs and interfaces (e.g., 4–20 mA, RS232/RS485) for easy integration into SCADA/DCS systems.

3) Product value

- Continuous, reliable monitoring that supports potable water safety and regulatory compliance.

- Reduced operational cost and operator exposure through non-toxic reagents and simplified maintenance.

- Lower downtime and faster recovery after alarms thanks to automated purging and restart routines.

- Actionable, integrable output and data-logging capabilities for process control, trend analysis and reporting.

- Scalable solution that can serve a wide concentration range, reducing the need for multiple instruments.

4) Product advantages

- Proven design and independent intellectual property (BOQU-developed technologies), demonstrated by related online analyzers in the company portfolio.

- Patented gas–liquid separator and flow-injection approach reduce pre-treatment needs and maintenance compared with many traditional analyzers.

- Wide dynamic range and automatic enrichment let the instrument measure from trace levels to high concentrations with fewer manual interventions.

- User-friendly operation: touchscreen interface, adjustable sampling/calibration intervals, and automatic maintenance routines.

- Manufacturer support: experienced production, strict QC, available inventory, and aftermarket support (training, periodic maintenance guidance).

5) Application scenarios

- Continuous online monitoring at potable water treatment plants (raw water, process streams and finished water).

- Distribution network and reservoir monitoring to detect contamination events or treatment upsets.

- Source-water quality surveillance at intake points and environmental monitoring stations.

- Integration into municipal or industrial SCADA/DCS for real-time process control and regulatory reporting.

- Laboratory or field-based semi-automated monitoring where low reagent toxicity and minimal pretreatment are priorities.
