BetzDearborn PQ682

Summary

Product identification

BetzDearborn PQ682 is a liquid blend for internal boiler water treatment.

Description and use

BetzDearborn PQ682 is a precipitating boiler water treatment formulated from a unique blend of polymers, sequestrants, and inorganic precipitating agents. It functions by removing calcium hardness from boiler water as calcium phosphate and precipitating magnesium hardness as magnesium hydroxide and/or magnesium silicate.

The product is designed to:

• Provide superior control of deposit formation.
• Prevent the formation of both hardness and metal oxide deposits.
• Distort crystal growth and reduce suspended particle size.
• Reduce the attraction between boiler tube walls and suspended particles.
• Promote surface adsorption and distortion of deposit particle crystal lattices.
• Result in significantly reduced scale potential and cleaner heat transfer surfaces.
• Maximize boiler reliability.

Treatment and feeding requirements

• Proper treatment levels depend on installation-specific factors.
• The product should be used according to SUEZ-established control procedures for a specific application.
• BetzDearborn PQ682 may be fed neat or diluted with softened makeup, condensate, or feedwater.

Packaging information

BetzDearborn PQ682 is available in a variety of containers and delivery methods. Contact SUEZ for details.

Storage

• Store at moderate temperatures.
