PolyFloc AE1115

Summary

Product identification

PolyFloc AE1115 is an anionic, low charge density, high molecular weight, polymeric flocculant. It is a liquid emulsion.

Description and use

PolyFloc AE1115 is designed for use as a coagulant aid or flocculant in industrial clarification, thickening, and sludge dewatering processes. It can be applied in both influent and effluent water treatment.

The product helps to:

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

Treatment and feeding requirements

Preparation

• PolyFloc AE1115 must be dissolved in water before use.
• Prepare solutions in a batch fashion by slowly adding the pre-mixed polymer to the vortex of an agitated tank. Do not add water to the neat polymer.
• Recommended initial makedown solution concentration: 0.5% (range: 0.3 to 1%).
• Use low speed (350 rpm) mechanical agitation until complete dissolution. Avoid high shear or excessive agitation after dissolution.
• Diluted solutions are recommended for use within 24 hours for maximum activity.
• Continuous makedown systems are an option for more reliable results.

Dilution

• Further dilution of the stock solution to approximately 0.1% enhances performance in most applications.
• For dewatering applications, a dilution to approximately 0.25% may be more practical.

Feeding

• Diluted product can be fed by pump, eductor, or gravity flow.
• Feed to a point of good mixing, but not violent agitation. High-speed mixing decreases polymer activity.
• Pumps for transferring the solution should be positive displacement gear or piston pumps.

Materials of construction

• Liquid-side components (tanks, pumps, piping) can be constructed of stainless steel or most plastics, with the exception of LD polyethylene and polypropylene.
• Mild steel is acceptable only if contamination by corrosion products is not critical.
• Viton and Tygon rubbers are acceptable for pump components and hose linings.

Storage and handling

Storage

• Store at moderate temperatures of 45 to 100°F (7 to 38°C).
• Protect from freezing.
• Bulk containers outdoors may require insulation and heat tracing.
• Neat polymer should be recirculated or mixed periodically (one container volume per day) to avoid product separation.

Handling

• Spilled polymer is very slippery.
• Small spills: wash down with copious amounts of water.
• Large spills: contain, absorb on inert material, dispose as solid waste, then flush with water.
