Identification of Microplastics Using the 8700 Laser Direct Infrared Imaging (LDIR) System

Contamination in our waterways, soil, air, and drinking water from microplastics is gaining significant public interest due largely to its emergence as an environmental threat. Researchers are now working towards standardized analytical solutions to best characterize these small particles in terms of chemical identity, size, shape, and total mass.

Organizations such as the National Oceanic and Atmospheric Administration define a microplastic as any particle of a plastic polymer that is less than 5 mm in size. However, it is smaller microplastic particles, less than 100 μm in size, that are often of the most interest. They are not visible to the naked eye and can make their way into the food chain.

EnviroTech – Transforming Wastewater Treatment with TOC Monitoring

Organic load is one of the most important parameters for discharge control of municipal and industrial wastewater. Permissible limits are guided through regulations and must be monitored accordingly. However, further opportunity to optimize plant performance exists by monitoring organic loading in upstream treatment processes.

The use of on-line controls allows limit values to be adhered to, products to be saved, and plants to be protected against unforeseen events. Total Organic Carbon (TOC) is the most suitable parameter to measure organic load. The use of TOC analysis offers shorter measuring cycles without hazardous waste and is better suited for on-line analysis compared to conventional methods such as COD or BOD.


What you’ll learn

  • Differences between TOC, BOD and COD, and why TOC is more suitable for on-line control
  • Differences in TOC technologies
  • How TOC can help optimize your plant
  • Examples and case studies of how TOC can be utilized
