Novus CE2653E

Summary

Product identification

• Product Name: Novus* CE2653E
• Product Type: Liquid, high molecular weight cationic emulsion polymer

Description and Use

Novus CE2653E is a structured copolymer designed for solid/liquid separation applications and sludge dewatering in industrial wastewater.

Typical Applications

• Effective in dewatering sludge in high shear systems, such as centrifuges.
• Particularly suited for dewatering biological (secondary) waste sludges.
• Benefits include higher solids capture, drier cake, cleaner effluent, and increased throughput.
• Effective in dewatering wastes in the organic chemical, oil refining, steel, aluminium, food, pharmaceutical, and paper industries.

Treatment and Feeding Requirements

Initial Preparation

• Thoroughly agitate with a drum mixer or recirculating pump for 30 to 60 minutes to ensure homogeneity before initial use.
• Remix for several minutes daily.
• Bulk system recirculation should operate for 30 to 60 minutes daily.
• Avoid water contamination in open containers.

Stock Solutions Preparation

• Make-down Concentration: Prepare a 0.5% to 1.0% solution in the make-down unit.
• Process:
  1. Fill the solution preparation tank with water until the agitator blade is fully immersed.
  2. Begin agitating.
  3. Slowly add the premixed polymer to the solution tank through a disperser unit or into the vortex. Do not add water to polymer.
  4. Continue filling the tank with water to achieve the 0.5% to 1.0% concentration.
  5. Mix for an additional 10 to 20 minutes at low speed (350 rpm) for activity development. Avoid high speed agitation.
• Holding Tank: Transfer the stock solution to a holding tank.
• Application Concentration: Further dilute to approximately 0.2% before the point of application.
• Feed Type: Continuous feed is recommended.

Pumping and Materials of Construction

• Neat Product: Can be handled with gear or diaphragm pumps suitable for viscosities up to approximately 2500 cps.
• Tank, Tubing, Piping, Pumps: Type 304 or 316 stainless steel, Teflon, and rigid PVC are satisfactory.
• Pump Components and Hose Linings: Viton and fluorosilicon type rubbers are suitable.
• Short-term Installations: Flexible PVC tubing (e.g., Tygon*), Buna-N, and Neoprene rubber may be used but may not be satisfactory in permanent applications.
• Temporary Use: Mild steel and copper alloys can be used if discoloration from corrosion products is acceptable.
• Stock Solutions: Handle with the same materials of construction.
• Metering: Positive displacement pumps (gear or piston) can be used.
• Bulk Tank Storage: Should include a desiccant and recirculation system.

Packaging Information

Novus CE2653E is available in a variety of containers. Consult a SUEZ representative for packaging alternatives.

Storage and Handling

• Storage Temperature: 4 to 32°C (39 to 89°F). Protect from freezing.
• Bulk Containers: Insulate against extreme heat, cold, and temperature variations.
• Neat Polymer: Recirculate or mix periodically to prevent product separation. Recirculate one container volume per day.
• Shelf Life: Six months.
• Spills: Spilled polymer is very slippery. Use precautions to avoid spills.
  • Small Spills: Wash down with copious amounts of water.
  • Large Spills: Contain, absorb on inert material, and dispose of as solid waste before flushing with water.
  • Wet Areas: Use sand, grit, or other suitable material for traction.
