BetzDearborn AE1115

Summary

Product Identification

• Product Name: BetzDearborn AE1115
• Product Type: Anionic, low charge density, high molecular weight, polymeric flocculant.
• Form: Liquid emulsion

Description and Use

BetzDearborn AE1115 functions as a coagulant aid or flocculant in industrial water treatment programs for clarification, thickening, and sludge dewatering. It is designed to reduce floc carryover and increase throughput.

Typical Applications

• Solids separation in influent and effluent water treatment.
• Settling lime precipitate in raw water lime/soda softeners.
• Clarification of iron oxide suspensions from steel industry wastewaters.
• Separation of precipitated hydrous metals in finishing water wastes.
• Reduction of fines in thickener effluents from blast furnace, steel mill scale, and BOP scrubber operations.
• Providing clean effluent from automotive oily waste treatment processes.
• 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.
• Sludge dewatering aid, producing clean filtrate, high solids capture, and a drier cake.
• Ore concentration process in the mining industry to improve filter press efficiency.

Treatment and Feeding Requirements

• Make-down: Must be dissolved in water before use.
  • Batch Method: Slowly add the 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: Low speed (350 rpm) mechanical agitation until complete dissolution. Avoid high shear or excessive agitation once dissolved.
  • Solution Stability: Diluted solutions recommended for use within 24 hours.
  • Continuous Systems: Available for more reliable results.
• Further Dilution: Approximately 0.1% enhances performance in most applications. For dewatering, approximately 0.25% may be more practical.
• Feeding: Can be fed by pump, eductor, or gravity flow to a point of good mixing (not violent agitation). High-speed mixing decreases activity.
• Transfer Pumps: Positive displacement gear or piston pumps are recommended for transferring the solution.
• Material Compatibility:
  • Liquid-side components (tanks, pumps, piping): Stainless steel or most plastics (excluding LD polyethylene and polypropylene). Mild steel acceptable only if corrosion product contamination is not critical.
  • Pump components and hose linings: Viton and Tygon rubbers are acceptable.

General Properties

Physical properties are available on the Material Safety Data Sheet.

Packaging Information

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

Storage and Handling

• Storage Temperature: Moderate temperatures (7 to 38°C). Protect from freezing.
• Bulk Storage: Insulate and heat trace if necessary for outdoor storage.
• Neat Polymer: Recirculate or mix periodically to avoid product separation (one container volume per day recommended).
• Shelf Life: Recommended six months.
• Spills: 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.
