Microscopic Particulate Analysis

Introduction In 1989 the EPA promulgated the Surface Water Treatment Rule (SWTR) in response to the 1986 Amendments to the Safe Drinking Water Act (SDWA). The overall goal of the SWTR is to protect consumers from pathogens. The SWTR recommends a multiple-barrier approach including source water protection, filtration and disinfection when surface water is used as source water for drinking. The ...

Particle removal efficiency of Nano alumina fiber filters

A 2 nanometer alumina fiber is combined with a microglass fiber to produce a nonwoven filter. Its pore size is 2 microns, yet it is functionally rated at 0.03 microns. Data are presented showing dirt ...

Sterlitech to Provide Larger Scale Membrane Skids for Research and Industry Customers

These pilot skid systems are specifically designed for pilot testing of spiral wound membrane filters or small scale filtration processes. They offer more than 200 times the filtration surface available in standard bench-top filtration systems, ...

Seawater Reverse Osmosis Pre-Treatment / Seawater Reverse Osmosis Post-treatment

Pre-treatment is important when working with RO and nanofiltration (NF) membranes due to the nature of their spiral wound design. The material is engineered in such a fashion to allow only one way flow through the system. As such the spiral wound design doesn't allow for backpulsing with water or air agitation to scour its surface and remove solids. Since accumulated material cannot be removed ...
