NEMeau

Automated Online Monitoring of VOCs in Water

NEMeau, the new extractor of molecules in water by Chemlys

Near real-time, laboratory-grade analysis of Volatile Organic Compounds directly on your process.

NEMeau, the Bridge Between Water Sampling and Instant Results

NEMEAU is an autonomous sampling station designed for the continuous monitoring of Volatile Organic Compounds (VOCs) and Total hydrocarbons (THCs) in water.

NEMEAU automates the extraction of dissolved gases using two proven principles: sparging (bubbling) and vacuum extraction. This ensures that the collected gases are analyzed with exceptional repeatability and accuracy.

Driven by an embedded controller, NEMEAU is designed to integrate seamlessly into any industrial environment.

Protecting Water Quality and Process Integrity

NEMEAU is a dedicated solution for industrial facilities that need to monitor and analyze dissolved compounds in their wastewater discharge.

Designed for versatility, NEMEAU handles both clear effluent and water with high particulate loads without compromising system integrity. Its robust architecture ensures long-term reliability and simplified maintenance, thanks to integrated, automated vacuum-assisted cleaning cycles.

To ensure maximum extraction efficiency and analytical precision, NEMEAU incorporates high-end technical features designed for the most demanding environments:

  • Integrated Level Sensors: For precise sample volume control.
  • Automated Overflow Protection: Ensuring system safety and preventing process spillage.
  • High-Precision Pressure & Temperature Monitoring: Continuous tracking for optimal extraction conditions.
  • Quick-Release Extraction Cell: Fully removable with a secure clamping screw for easy maintenance and cleaning.
  • Regulated Sparging System: Precisely controlled bubble generation for optimized gas-liquid transfer.
  • High-Integrity Sealing: Specialized gaskets to ensure a leak-proof flow path and preserve sample integrity.
  • Heated Extraction Cell (Optional): To enhance the recovery of heavier or less volatile compounds.
  • Remote Control Unit: Allows for flexible installation and safer operation away from the sampling point.

The NEMEAU solution is divided into two distinct modules: a high-performance Extraction Cell and a dedicated Control Unit equipped with an intuitive touch-screen interface.

Operating Principle:

The NEMEAU system samples a controlled sample volume and initiates a high-efficiency extraction sequence combining sparging (bubbling) and vacuum technology. This dual-action process ensures the optimal recovery of Volatile Organic Compounds (VOCs), which are then transferred to a pre-configured industrial GC for detailed analysis.
By utilizing continuous sampling, the system ensures your data remains current, providing real-time insights into your water quality.

Self-Cleaning & Repeatability: To ensure consistent accuracy, NEMEAU executes an automated cleaning cycle using vacuum and fresh water (mains or filtered) after every analysis. High-precision sensors monitor volume, pressure, and temperature to guarantee unmatched repeatability. Enhanced Recovery: An optional heated extraction cell is available to improve the recovery of water-soluble or heavier compounds.

NEMEAU serves as the central controller for your entire online monitoring setup. You can track your results, manage methods, and monitor system health via the built-in 7" touch screen or our license-free web interface.

When coupled with an industrial GC, NEMEAU provides a comprehensive suite of features:

- Real-Time Status Monitoring: Instant visibility of system states (Ready, Analyzing, Communication Alert).
- Threshold Management: Easily define and manage critical alarm levels.
- Automated Method Loading: Select and load specific analytical methods on the fly.
- Intelligent Feedback Loops: Implement conditional logic—for example, automatically loading a "high-resolution" method if a threshold is exceeded.
- Real-time trend charts
- Calibration Management: Perform GC calibration directly through the extraction cell.
- Data Archiving & Traceability: Comprehensive logging of all results and threshold exceedances for regulatory compliance.

Proactive Risk Management By integrating NEMEAU with an industrial GC, you move from reactive to proactive monitoring. Anticipate threshold exceedances before they impact your site's environment or regulatory standing.
