Novus CE1686

Summary

Product identification

• Product Name: Novus* CE1686
• Product Type: Cationic emulsion polymer

Description and use

Novus CE1686 is a liquid, high molecular weight cationic emulsion polymer designed for solid/liquid separation applications and sludge dewatering in industrial wastewater. It is particularly effective in the organic chemical, oil refining, steel, aluminium, food, and pharmaceutical industries.

Benefits include:

• Increases efficiency of sludge dewatering operations.
• Improves suspended solids removal operations and effluent quality.
• Improved cost/performance.
• Produces shear resistant floc.
• Easily fed liquid emulsion.
• Higher solids capture.
• Drier cake.
• Cleaner effluent.
• Increased throughput.

Treatment and feeding recommendations

Preparation

• Prior to initial use, Novus CE1686 should be agitated with a drum mixer or recirculating pump for 30 to 60 minutes to ensure homogeneity.
• Remix the polymer for several minutes each day thereafter.
• Bulk system recirculation systems should be operated for 30 to 60 minutes daily.
• Avoid water contamination from condensation or rain in open containers.

Stock solutions preparation

• Make-down Unit (Continuous System): The concentration range required for proper inversion is 0.5% to 1.0%. After inversion, the solution can be further diluted for application.
• Batch System:
  1. Fill the solution preparation tank with water until the agitator blade is fully immersed.
  2. Begin agitating and slowly add the premixed polymer (do not add water to polymer).
  3. Continue filling the tank with water to achieve a 0.5% to 1.0% solution.
  4. Mix for an additional 10 to 20 minutes at low speed (350 rpm) to complete activity development. Avoid high-speed agitation.
  5. Transfer the stock solution to a holding tank, further diluting to approximately 0.2% before the point of application.
• Continuous feed is recommended.

Material compatibility

Neat polymer handling

• Gear or diaphragm pumps suitable for viscosities up to approximately 1500 cps.
• Satisfactory materials: Type 304 or 316 stainless steel, Teflon, PE/PP for tanks, tubing, piping, and pumps.
• Pump components and hose linings: Viton, fluoro-silicon type rubbers.
• Short-term installations: Flexible PVC tubing (e.g., Tygon), Buna-N, Neoprene rubber.

Stock solutions handling

• Should be handled with the same materials of construction as neat polymer.

General material considerations

• Mild steel and copper alloys may cause discoloration of the polymer by corrosion products.

Storage and handling

• Storage temperature: 4 to 32°C. Protect from freezing.
• Bulk containers should be insulated to protect from extreme temperatures.
• Neat polymer should be recirculated or mixed periodically (one container volume per day) to avoid product separation.
• Shelf life: Six months.
• Spilled polymer is very slippery.
• Small spills can be washed down with copious amounts of water.
• Large spills should be contained, absorbed on inert material, and disposed of as solid waste before flushing with water. Use sand or grit for traction in wet areas.
