]]> Counting Microplastics in Wastewater https://www.pmeasuring.com/blog-counting-microplastics-in-wastewater/ Tue, 06 Jun 2023 18:22:54 +0000 https://www.pmeasuring.com/?p=135387 This paper discusses the goal to minimize microplastics in aquatic systems and validating the results. The authors of this paper propose a new approach of measurement and filtration that has the opportunity to reduce the microplastics that end up in our water.  This alternative method would allow manufacturers to measure particles in treated textile water continuously for particles that are as small as 2.0 microns.

New flow imaging technologies and therapeutic protein solutions widened the scope of USP 1788. Three primary technologies are discussed in each of the sub-parts of the guidance document: Light Obscuration (LO) is still the preferred first-pass method for the USP Normative chapters. If a solution is...
