Malvern dives into quantifying nanoparticle concentration and size to optimize filtration processes

With the increasing demands on water supplies and tighter regulations, much research is being done on water treatment processes. Subjects of study include improving processes to allow treated water to be used in secondary applications, optimizing filtration processes to remove biological contaminants and reduce membrane fouling, monitoring filter breakthrough to minimize maintenance requirements or contamination, and verifying ability to remove the increasing load of nanoparticulates in the waste water stream.

Numerous technologies exist for monitoring particle size and concentration in the micron size range, but Nanoparticle Tracking Analysis (NTA) is a unique technology that provides greater insight into the sub-micron size range that is so important to many of these advanced water treatment processes.
