Novus CE1685

Summary

Product Identification

• Product Name: Novus* CE1685
• Description: Cationic emulsion polymer, high molecular weight, high charge density linear copolymer.
• Application: Solid/liquid separation and sludge dewatering in industrial wastewater applications.

Description and Use

Novus CE1685 is a liquid, high molecular weight, high charge density cationic emulsion polymer designed for solid/liquid separation and sludge dewatering. It is effective in industries including:

• Organic chemical
• Oil refining
• Steel
• Aluminum
• Food
• Pharmaceutical

Benefits include higher solids capture, drier cake, cleaner effluent, and increased throughput.

Treatment and Feeding Recommendations

Preparation

• Initial Agitation: Agitate thoroughly with a drum mixer or recirculating pump for 30 to 60 minutes to ensure homogeneity.
• Daily Remixing: Remix the polymer for several minutes each day. Bulk system recirculation should operate for 30 to 60 minutes daily.
• Contamination Avoidance: Avoid water contamination from condensation or droplets in open containers.

Make-down and Dilution

• Continuous System: Required concentration for proper inversion is 0.5% to 1.0%.
• Batch System (Stock Solutions):
  • Prepare stock solutions in a solution preparation tank.
  • Add premixed polymer to water with agitation, do not add water to polymer.
  • Achieve a 0.5% to 1.0% solution.
  • Mix for an additional 10 to 20 minutes at low speed (350 rpm) to complete activity development. Avoid high-speed agitation.
  • Transfer to a holding tank and dilute further to approximately 0.2% before the point of application.
• Feed: Continuous feed is recommended.

Mechanical / Hydraulic

Pumping

• Neat Polymer: Can be handled with appropriately sized gear or diaphragm pumps suitable for viscosities up to approximately 1500 cps.
• Stock Solutions: Positive displacement pumps such as gear or piston pumps can be used.

Materials of Construction

• Tanks, Tubing, Piping, Pumps: Type 304 or 316 stainless steel, Teflon, and PE/PP are satisfactory.
• Pump Components and Hose Linings: Viton and fluoro-silicon type rubbers.
• Short-term Installations: Flexible PVC tubing (e.g., Tygon), Buna-N, and Neoprene rubber may be suitable.
• Less Preferred Materials: Mild steel and copper alloys may be used if discoloration from corrosion products is acceptable. Stock solutions should use the same materials.

Storage

• Bulk Tank Storage: Should include a desiccant and recirculation system.

General Properties

Physical properties are detailed in the Material Safety Data Sheet (MSDS), available on request.

Packaging Information

Novus CE1685 is a liquid emulsion, available in various containers. Consult a SUEZ representative for alternatives.

Storage and Handling

• Storage Temperature: 4 to 32°C. Protect from freezing and extreme temperature variations.
• Shelf Life: Six months recommended.
• Handling: Neat polymer requires periodic recirculation or mixing to prevent separation (one container volume per day). Spilled polymer is slippery; use precautions.
• Spill Cleanup:
  • Small spills: Wash down with copious amounts of water.
  • Large spills: Contain, absorb with inert material, dispose of as solid waste, then flush with water. Use sand or grit for traction in wet areas.

Safety Precautions
