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
Industrial Wastewater Treatment Applications include (but not limited to):
- 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
This criterion helps to determine whether a diaphragm pump or a rotary gear pump is the best choice for a specific application.
