Water Treatment

Water Treatment is in Pulsafeeder’s DNA

For more than 70 years, Pulsafeeder pumps have been used to treat water at hundreds of industrial & municipal plants around the globe.

Municipal Water Treatment Applications include (but are not limited to):
  • Metering of sodium and calcium hypochlorites for disinfection
  • Acid and caustic injection for pH control
  • Injection of potassium permanganate for manganese and iron removal
  • Metering of alum or sodium aluminate as a coagulant aid
  • Metering of polymers for primary coagulation
  • Injection of filter aid slurries
  • Metering of lime slurries in softening and pH control
  • Ammonium sulphate or aqua ammonia in production of chloramines
  • Metering activated carbon slurries for taste and odor control
  • Injection of fluoride compounds


Cooling Tower Water Treatment
Boiler Water Treatment
Industrial Wastewater Treatment Applications
  • Metering of sodium hypochlorite and hydrogen peroxide for disinfection
  • Metering acids and caustics for pH control
  • Sodium bisulfite metering for de-cholorination
  • Metering of alum or sodium aluminate as a coagulant aid
  • Anionic and cationic polymer injection for phosphate removal, coagulation and filtration
  • Caustic soda (sodium hydroxide) metering for metal removal, pH control, and cyanide removal
  • Acid and caustic injection for regeneration of resins
  • Injection of potassium permanganate for manganese and iron removal
  • Metering of Bromine for disinfection (for cooling towers)
  • Injection of copper sulfate for algae control in cooling tower water
  • Metering of polymers for primary coagulation
  • Ferric chloride and alum injection for coagulation
  • Copper sulfate injection for algae control
  • Methanol injection for denitrification
  • Metering of lime slurries for pH control, corrosion control and coagulation
  • Metering activated carbon or diatomaceous earth slurries for odor and color control
Metering pumps used to deliver chemicals should be selected by criteria specific to the process, such as:
  • Flow Rates & Pressure – as required by the process
  • Corrosion resistance – to the chemical being pumped
  • Accuracy – to deliver precisely the amount of chemical needed for a process
  • Reliability – to ensure sustained and predictable operation
  • Simplified maintenance – to minimize costs and maximize plant uptime
  • Safety – to protect plant employees, and the surrounding environment
