Novus AE1784

Summary

Product identification

• Product Name: Novus AE1784
• Product Type: Liquid emulsion polymer

Description and Use

Novus AE1784 is a high molecular weight, medium charge density, anionic emulsion polymer. It is designed to function in industrial treatment programs as a coagulant aid, or flocculant, in clarification, thickening, and sludge dewatering processes.

Typical Applications

Novus AE1784 is a liquid emulsion that provides a cost-effective solution for various solids separation processes in both influent and effluent water treatment.

• Produces a fast-settling floc, reducing carryover when used with inorganic or cationic polymeric coagulants.
• Settles lime precipitate in raw water lime/soda softeners.
• Settles iron oxide suspensions from steel industry wastewaters.
• Settles precipitated hydrous metals in finishing water wastes.
• Reduces fines in blast furnace, steel mill scale, and BOP scrubber thickener effluents.
• Provides a clean effluent from automotive oily waste treatment processes.
• Increases settling in chrome/cyanide destruction units and heavy metal separation systems.
• Reduces oil in refinery and other industrial wastewaters by improving air flotation unit and API separator efficiencies.

Treatment and Feeding Requirements

• Novus AE1784 must be dissolved in water before use.
• Preparation: Slowly add the pre-mixed polymer to the vortex of an agitated tank. Do not add water to the neat polymer.
• Initial Make-down Concentration: Recommended at 0.5% (range 0.3% to 1%).
• Agitation: Low speed (350 rpm) mechanical agitation should continue until complete dissolution. Avoid high shear or excessive agitation once dissolved.
• Use of Diluted Solutions: Recommended to be used within 24 hours for maximum activity.
• Further Dilution: Diluting to approximately 0.1% enhances polymer performance in most applications. For dewatering, diluting to approximately 0.25% may be more practical.
• Feeding: Diluted product can be fed by pump, eductor, or gravity to a point of good mixing without 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 (tanks, pumps, piping): Stainless steel or most plastics (excluding LD polyethylene and polypropylene). Mild steel is acceptable only if corrosion product contamination is not critical.
  • Pump components and hose linings: Viton and Tygon rubbers are acceptable.

Packaging Information

Novus AE1784 is available in a variety of containers. Contact your SUEZ representative for more information.

Storage and Handling

• Storage Temperature: 7 to 38°C. Protect from freezing.
• Bulk Containers: Insulate and heat trace (if necessary) if stored outdoors.
• Neat Polymer: Recirculate or mix periodically to avoid separation (one container volume per day).
• Shelf Life: Recommended at six months.
• Spills:
  • Spilled polymer is very slippery.
  • Small spills: Wash down with copious amounts of water.
  • Large spills: Contain, absorb on inert material, dispose of as solid waste, then flush with water.
