Application Note
With Thermo Scientific Masterflex Pumps, Wastewater Treatment Plants Can Finally Optimize NaOCl Feed
Gregg E. Johnson, Thermo Fisher Scientific
A common problem with feeding commercial sodium hypochlorite (NaOCl) and other high strength chemical oxidants is outgassing. Outgassing occurs when a pocket of vapor forms in the fluid line, obstructing normal flow. Outgassing often vapor locks chemical metering pumps and can lead to system leaks and result in unscheduled downtime and poor process performance. Another common problem with feeding NaOCl is hard water scale, which can completely jam the operation of a pump's wet end.
