In the article High Speed Water Sterilization Using One-Dimensional Nanostructures, silver nanoparticles and carbon nanotubes were used to make a cotton fabric which kills bacteria by applying a low voltage across this conductive material.
The research was completed at Stanford University.
The electrical current that helps do the killing is only a few milliamps at 20volts. The power can be supplied by a small solar panel or a couple 12-volt car batteries. The electrical current can also be generated from a stationary bicycle or by a hand-cranked device.

Presentation on Condensate Polisher ROI
As I alerted in a previous post, Kevin Preising of Res-Kem gave a webcast entitled "Reuse It or Lose It - The Economics of Condensate Polishing". This excellent webcast was given at the GlobalSpec Industrial Processing virtual trade show on August 25 showing how a condensate polisher can pay for itself in 9.6 months! You sve energy and water treatment chemicals.
You can see this presentation any time, day or night through GlobalSpec.

Fleck and Aquamatic Valve Service Training
On July 27-28, fifteen of Res-Kem's service supervisors and technicians attended a training program on servicing Fleck valves and Aquamatic valves. These people represented the Eastern Service Region and cover areas from Maine to Florida as far west as Pittsburgh.
From this training program, Res-Kem now has additional coverage for softener and filter install, start-up and repair throughout the Eastern Region.
We were fortunate to again have Dave Smith from Pentair to lead the education on the features, maintenance, and repair of Pentair Fleck light industrial and commercial valves. Dave gave a hands-on trouble-shooting and repair training program on Fleck valves. He had the Pentair Fleck 2850 and Fleck 9100 valves on hand so each person could tear down and rebuild each of the valves.
Bob Hader, Service Manager of Res-Kem, led the program to identify, disassemble, and repair common cast iron Aquamatic V42 series, plastic Aquamatic K530 series & plastic K520 series Aquamatic valves. These valves are the most frequently found valves on water
You are welcome to view our YouTube videos on identifying which valve you have, how to use the ordering guides, selecting the correct valve/parts, and how to repair/replace these valves. You can also access the videos through our website.
Michael Urbans gave a demonstration of a dual tank softener in Res-Kem's wet test area. Our service technicians were able to diagnose a 10 year old problem sofetner valve returned from a customer.
If you ever have questions about Fleck or Aquamatic valves, please feel free to contact our expert Mike Polito at 610-358-0717. If you have an Aquamatic. Fleck or Autotrol valve at your plant and need a replacement or replacement parts, please take photos and send them to mpolito@reskem.com.
