FRED-Acidity™

A FRED-Chem Sensor

The Field-Ready Acidity Detector® analysis system for acid mine drainage.

We're automating your field monitoring system.

Field monitoring is difficult, often lacking real-time sensors or robust systems that can allow for continuous sampling. Sites must be driven to, analytical labs introduce delays, and field kits are difficult to use or lack data integrity. FRED-Acidity is designed to be robust, automated, and easy to use for a variety of applications. The automated design decreases rework, making analysis much simpler to perform and allowing for better process control of treatment or environmental assessment plans. Reduce the time spent travelling to the site more often than required and provide needed information to process engineers without the hassle of an expensive custom installation.

Applications

Acid mine drainage requires active management of acidic conditions to direct lime or caustic dosing. Rapid detection of acidity is critical to alleviate the financial, environmental, and social implications of site management. Operators may wait hours or even days for results from the analytical lab, while water is being inappropriately treated leading to added expense and potential environmental impacts.

Rapid and portable acidity detection in various water samples.

The system is designed for acidity measurement using a spectroscopy-based method of detection. The indicator and titrant are built in a sealed cartridge. The cartridge is able to strategically dose water samples in the field kit on site, without any sample pre-treatment. Detection of acidity at trace levels is achieved in a rapid timeframe and data is transmitted wirelessly (or via USB) for further analysis. The product is an ideal platform for rapid analysis at sample sites.
