Mag Drive Pumps for Odor Control Applications

When the goal is clean air and safe environmental conditions, reliable operations are critical. Mag drive pumps deliver the leak-free, long-lasting performance necessary for odor control applications. Finish Thompson’s durable mag drive pumps can handle the variety of harsh chemicals involved in these processes, to provide safe, dependable operations for fume scrubbers and other odor control applications.

A good example is municipal waste water treatment plants (sewage treatment). Hydrogen sulfide occurs naturally through the anaerobic decay of organic matter. Hydrogen sulfide is corrosive, toxic, and smells like rotten eggs. It has a very low odor threshold so it is easily detected in very low concentrations. Homes and businesses surrounding a sewage treatment plant expect the hydrogen sulfide to be removed. Typical chemicals used in the liquid solution to oxidize hydrogen sulfide include sodium hypochlorite (bleach) and sodium hydroxide (caustic).

Typical Applications

  • Sewage treatment plants
  • Paper mills
  • Air pollution control
  • Steel manufacturing
  • Chemical processing
  • Food processing
  • Pharmaceutical
