PolyFloc AP1142

Summary

Product Identification

PolyFloc AP1142 is a nonionic, high molecular weight, polymeric flocculant.

Description and Use

PolyFloc AP1142 is designed for use in industrial treatment programs as a coagulant aid or flocculant in clarification, thickening, and sludge dewatering processes. It is a free-flowing powder that functions in both influent and effluent water treatment.

Key applications include:

• Reducing floc carryover when used with inorganic or cationic polymeric coagulants.
• Settling iron oxide suspensions from steel industry wastewaters.
• Settling precipitated hydrous metals in finishing water wastes.
• Reducing fines in effluents from blast furnace, steel mill scale, and BOP scrubber thickeners.
• 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.
• Serving as a sludge dewatering aid, producing clean filtrate, high solids capture, and a drier cake.

Treatment and Feeding Requirements

• PolyFloc AP1142 should be dissolved in water before use.
• Maximum practical stock solution concentration is 0.5% by weight.
• Dissolution is typically accomplished in about one hour with air or low-speed (350 rpm) mechanical agitation.
• Warm water (not exceeding 150°F or 65°C) can accelerate dissolution.
• Avoid high shear or excessive agitation after dissolution.
• Dissolved solutions are recommended for use within 24 hours for maximum activity.
• Further dilution to approximately 0.05% by weight (10:1 ratio) enhances performance in most applications.
• For dewatering applications, dilution to approximately 0.25% may be more practical.
• Diluted product can be fed by pump, eductor, or gravity.
• Pumps for transferring solutions should be positive displacement gear or piston pumps.
• Materials compatible with liquid-side components include stainless steel, polyethylene, and polypropylene. Mild steel is acceptable only if corrosion product contamination is not critical. Viton and Tygon rubbers are acceptable for pump components and hose linings.

General Properties

Packaging Information

PolyFloc AP1142 is available as a dry powder in bags and drums.

Storage and Handling

• Store under dry, low humidity conditions.
• Seal opened containers before restorage.
• Spilled polymer is very slippery; scoop/wipe up spills before flushing with copious amounts of water.
