BetzDearborn AE1700

Summary

Product identification

BetzDearborn AE1700 is an anionic, low charge density, high molecular weight, polymeric flocculant. It is a liquid emulsion used as a coagulant aid or flocculant in clarification, thickening, and sludge dewatering processes.

Typical Applications

BetzDearborn AE1700 is designed for solids separation in industrial water treatment, including:

• Settling lime precipitate in raw water lime/soda softeners.
• Clarifying iron oxide suspensions from steel industry wastewaters.
• Dewatering precipitated hydrous metals in finishing water wastes.
• Reducing fines in thickener effluents from blast furnaces, steel mills, 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 and API separator efficiencies.
• Acting as a sludge dewatering aid, producing clean filtrate, high solids capture, and a drier cake.

Treatment and Feeding Requirements

Preparation

• Dissolution: Must be dissolved in water before use. Add pre-mixed polymer slowly to the vortex of an agitated tank. Do not add water to the neat polymer.
• Initial Concentration: Recommended initial makedown concentration is 0.5% (range 0.3% to 1%).
• Agitation: Use low-speed (350 rpm) mechanical agitation until complete dissolution. Avoid high shear or excessive agitation after dissolution.
• Solution Stability: Diluted solutions should be used within 24 hours for maximum activity.
• Continuous Systems: Continuous makedown systems are available for more reliable results.
• Further Dilution: Further dilution to approximately 0.1% typically enhances polymer performance. For dewatering applications, diluting to approximately 0.25% may be more practical.
• Feeding: Diluted product can be fed by pump, eductor, or gravity flow to a point of good mixing, but not violent agitation. High-speed mixing decreases polymer activity.
• Transfer Pumps: Positive displacement gear or piston pumps are recommended for transferring the solution.

Materials of Construction

• Liquid-side Components: Stainless steel or most plastics are suitable, except for LD polyethylene and polypropylene.
• Mild Steel: Acceptable only if contamination by corrosion products is not a critical concern.
• Seals and Linings: Viton and Tygon rubbers are acceptable for pump components and hose linings.

Packaging Information

BetzDearborn AE1700 is a liquid emulsion available in various containers. Contact SUEZ for details.

Storage and Handling

• Temperature: Store at moderate temperatures (7 to 38°C). Protect from freezing.
• Outdoor Storage: Bulk containers may require insulation and heat tracing if stored outdoors.
• Neat Polymer: Recirculate or mix periodically (one container volume per day) to prevent product separation.
• Shelf Life: Recommended shelf life is six months.
• Spills: Spilled polymer is very slippery. Small spills can be washed with copious amounts of water. Large spills should be contained, absorbed on inert material, disposed of as solid waste, and then flushed with water.
