Analyze bacteria performance in your Wastewater Treatment Plant in real-time


  • Product Overview

  • Technical Specifications

AS BioscopeInformation is at your fingertips with our hand-held portable Activated Sludge analyzer.

This simple to use instrument quickly measures bacteria performance inaerobic wastewater treatment facilities providing valuable information in the following application areas:

• Biodegradation rate profiling. Assessing how your plant is performing under real time conditions.
• Bacterial health by comparing the current sample with the last ten measurements at a specified point.
• Energy Optimization by determining the critical oxygen point.
• Measuring DO and temperature levels at any selected point in your plant including RAS lines and Clarifiers.
• SVI and SSVI performance.

The AS Bioscope has been optimized to provide very simple measurements of:

• OUR (Oxygen Update Rate)
• DO (Dissolved Oxygen)
• Critical Oxygen Point
• Temperature
• Settlement
