UPW-BK10 Automatic Rapid BOD Analyzer

Product Introduction
The UPW-BK10 Automatic Rapid BOD Analyzer is an advanced water quality testing instrument designed to measure biochemical oxygen demand (BOD) using the microbial membrane electrode method. It employs continuous-flow measurement and an automated peristaltic pump system to deliver samples at a controlled rate, enabling automatic sampling, measurement, cleaning, and waste discharge.
The analyzer detects changes in dissolved oxygen caused by microbial activity. When a sample containing biodegradable organic matter passes through the flow cell, specialized microorganisms consume oxygen as they metabolize the organic compounds. The resulting change in dissolved oxygen is detected by the oxygen electrode and correlated with the organic matter content to calculate the BOD value.
Designed for laboratory and industrial wastewater testing, the UPW-BK10 offers a measurement range of 2–4000 mg/L with automatic dilution, adjustable sample measurement times of 8–30 minutes, and a relative standard deviation of ≤5%. Its integrated three-electrode sensor, electronic temperature control, and 7-inch color touchscreen support convenient operation and consistent analytical performance.
The instrument complies with the Chinese environmental standard HJ/T 86-2002, Water Quality—Determination of Biochemical Oxygen Demand (BOD)—Rapid Determination Method Using Microbial Sensors. The method is also listed as a Class A method in the fourth edition of Water and Wastewater Monitoring and Analysis Methods, according to the supplied product information.

Performance Features
1. Microbial Membrane Electrode Technology: Uses specialized BOD microorganisms to measure oxygen consumption associated with biodegradable organic matter.
2. Fully Automatic Operation: Automatically manages standard solutions, cleaning solutions, samples, and waste discharge, reducing manual intervention.
3. Continuous-Flow Sampling: A peristaltic pump provides controlled, continuous sample delivery for automated measurement.
4. Integrated Three-Electrode Sensor: Incorporates a microbial electrode and reference electrode in an integrated sensor assembly for stable signal acquisition.
5. Integrated Flow and Measurement Cell: Combines the flow cell and measurement cell into one design for convenient cleaning and maintenance.
6. Precise Temperature Control: Features an electronic constant-temperature system with dual S-shaped gas and liquid flow paths to regulate the temperatures of samples and aeration air.
7. 7-Inch Color Touchscreen: Displays instrument status and measurement results through an intuitive touchscreen interface.
8. Data Storage and Printing: Supports measurement data storage and printing for laboratory records and reporting.
9. Long-Term Membrane Storage: The dry-layer microbial membrane can be stored under normal-temperature, dry conditions for more than one year, according to the manufacturer.
10. Convenient Microbial Membrane Maintenance: The dedicated BOD microbial membrane can be used without conventional biochemical culture preparation, with an activation service life exceeding 30 days.
11. Resistance to Interference: Specialized microorganisms are cultivated through long-term acclimation to improve tolerance to toxic substances and interfering components in complex industrial wastewater.
12. Automatic Dilution: Supports measurements up to 4000 mg/L through a utomatic dilution, expanding the applicable concentration range.

Working Principle
The UPW-BK10 Automatic Rapid BOD Analyzer operates on the microbial membrane electrode principle, using the relationship between microbial oxygen consumption and the biodegradable organic matter content of a water sample.
The measurement process follows these steps:
1. Automatic Sample Introduction: A peristaltic pump transports the sample through the analyzer's continuous-flow system.
2. Microbial Reaction: The sample passes through the measurement cell containing a specialized microbial membrane. Microorganisms consume dissolved oxygen while metabolizing biodegradable organic compounds.
3. Dissolved Oxygen Detection: The oxygen electrode detects changes in dissolved oxygen. In a blank buffer solution, microbial oxygen consumption is low; in a sample containing biodegradable organic matter, oxygen consumption increases.
4. Electrical Signal Conversion: The change in dissolved oxygen produces a corresponding change in the oxygen electrode's output current.
5. BOD Calculation: The instrument processes the signal change and calculates the BOD value based on the established relationship between the sensor response and organic matter concentration.
6. Automatic Cleaning and Waste Discharge: After measurement, the instrument automatically manages the cleaning solution and waste discharge to prepare for subsequent analyses.
This automated workflow enables rapid BOD testing with reduced manual handling and supports routine monitoring of water quality and wastewater treatment processes.
