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

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.
