Company Cod Bod Analyzer by BOQU

Product Overview

- BOQU’s COD/BOD analyzer solution includes the YCL-3100 Sample Filtration System as a pretreatment module designed for online water-quality monitoring. It prepares samples with high suspended solids or sludge for measurement by BOQU’s family of online analyzers (COD, BOD, ammonia, TN, TP and many metal/ion analyzers). The system is intended for indoor installation and centralizes sampling, homogenization, filtration and delivery to analyzers.

Product Features

- Two sampling modes: externally triggered or periodic sampling.

- Ultrafiltration with high precision (filters down to ~0.1–0.15 μm) to remove suspended solids.

- Built-in stirrer for full mixing/homogenization of the sample cup.

- Automatic self-cleaning of pipelines, cup and sedimentation tank after sampling.

- Alarm and switching-value outputs for status/remote control; compact footprint (1570×500×450 mm) and standard AC220 V power.

Product Value

- Ensures reliable, representative samples for online analyzers, improving measurement accuracy and repeatability.

- Reduces manual pretreatment and operator intervention through automated filtration and cleaning, lowering labor and contamination risk.

- Enables continuous, real-time monitoring of wastewater and surface water quality, supporting compliance, rapid decision-making and process control.

- Broad compatibility with many BOQU analyzers makes it a flexible front-end for multi-parameter monitoring.

Product Advantages

- Robust performance with high sludge volumes or floating solids—maintains reliable operation where coarse samples would otherwise block instruments.

- Integrated self-cleaning and scheduled maintenance (monthly short routine) reduce downtime and maintenance burden.

- Precise ultrafiltration and stirring deliver stable, homogeneous samples to downstream analyzers, enhancing analytical stability.

- Alarm outputs and external trigger options allow easy integration into automation systems and remote supervision.

- Backed by BOQU’s service commitments (rapid response to messages and complaints) and quality management processes.

Application Scenarios

- Municipal wastewater treatment plants (influent/effluent monitoring).

- Industrial effluent monitoring for chemical, petrochemical, pharmaceutical, textile, paper, food & beverage and metal-processing plants.

- Surface water and river monitoring stations.

- Power plants and cooling-tower blowdown monitoring.

- Any online monitoring installation that requires pretreatment of high-suspended-solids samples before COD, BOD, nutrient or trace-metal analysis.
