BetzDearborn AE1128

Summary

Product identification

• Product Name: BetzDearborn AE1128
• Product Type: Anionic, medium charge density, high molecular weight, polymeric flocculant.
• Form: Liquid emulsion.

Description and Use

BetzDearborn AE1128 functions as a coagulant aid or flocculant in industrial water treatment programs, specifically for clarification, thickening, and sludge dewatering processes. It is designed to reduce floc carryover and increase throughput.

Typical Applications

This product is a cost-effective solution for solids separation in both influent and effluent water treatment. It aids in:

• Settling lime precipitate in raw water lime/soda softeners.
• Clarifying iron oxide suspensions from steel industry wastewaters.
• Removing precipitated hydrous metals from finishing water wastes.
• Reducing fines in thickener effluents from blast furnace, steel mill scale, and BOP scrubbers.
• Providing a clean effluent from automotive oily waste treatment.
• Increasing settling in chrome/cyanide destruction units and heavy metal separation systems.
• Reducing oil in refinery and other industrial wastewaters by improving air flotation unit and API separator efficiencies.
• Acting as a sludge dewatering aid, producing clean filtrate, high solids capture, and a drier cake in the steel industry and other markets.

Treatment and Feeding Requirements

• Preparation: Must be dissolved in water before use. Add pre-mixed polymer to the vortex of an agitated tank. Do not add water to the neat polymer.
• Initial Concentration: Recommended 0.5% (range 0.3% to 1%).
• Agitation: Use low speed (350 rpm) mechanical agitation until complete dissolution. Avoid high shear or excessive agitation once dissolved.
• Solution Stability: Diluted solutions are recommended for use within 24 hours for maximum activity.
• Continuous Systems: Available for more reliable results.
• Further Dilution: Approximately 0.1% enhances polymer performance in most applications. For dewatering, approximately 0.25% may be more practical.
• Feeding: Diluted product can be fed by pump, eductor, or gravity to a point of good mixing (not violent agitation). High-speed mixing decreases activity.
• Transfer Pumps: Positive displacement gear or piston pumps are recommended.
• Materials of Construction:
  • Liquid-side components: Stainless steel or most plastics (except LD polyethylene and polypropylene).
  • Mild steel: Acceptable only if corrosion product contamination is not critical.
  • Seals/Hoses: Viton and Tygon rubbers are acceptable.

General Properties

Physical properties are detailed on the Material Safety Data Sheet.

Packaging Information

Available as a liquid emulsion in various containers. Contact a SUEZ representative for details.

Storage and Handling

• Storage Temperature: 7 to 38°C. Protect from freezing.
• Frozen Product: Thaw completely and mix thoroughly before use.
• Bulk Containers: Insulate and heat trace if stored outdoors and necessary.
• Neat Polymer: Recirculate or mix periodically to avoid separation (one container volume per day).
• Shelf Life: Recommended six months.
• Spill Cleanup: Spilled polymer is very slippery. Wash small spills with copious amounts of water. Contain and absorb large spills on inert material, dispose of as solid waste, then flush with water.
• Safety: Refer to the Material Safety Data Sheet for detailed information.
