Quantachrome Instruments has published a paper on the usefulness of zeta-potential measurements as it relates to moderating suspended solids in wastewater from plants producing biofuels.

The white paper focuses on how the measurements of zeta potential (the surface-related charge around a particle suspended in a fluid) can be used to understand how to flocculate (agglomerate) fine particles and conversely how to disperse flocculates into individual particles.

In addition to describing just what zeta potential is exactly, the article details a particular application relating to wastewater treatment in the growing field of biofuel production, in this case ethanol from corn.

Solid byproducts have to be removed and evaporated to dryness and this step is much more energy efficient when the solids are flocculated.

Knowing how to flocculate the solids is paramount and studying zeta potential is key to that knowledge.

The results of zeta potential measurements using Quantachrome’s Zeta-Reader, including images captured using the devices high magnification digital video system, are presented.

The white paper is entitled ‘Use of Zeta Potential in Wastewater Treatment’.
