• Limited resistance: Polypiperazine amide, polyvinyl difluoride and cellulose
• Not intended for use with: cellulose acetate membranes (may be damaged)
• Potential issue: Polyether urea and electrodialysis membranes may be irreversibly blocked by anionic surfactants.

Application

P3-ultrasil 110 is suitable for cleaning micro-, ultra-, nanofiltration, and reverse osmosis plants in the Dairy and Beverage Industries.

Mode of application

• Recommended concentrations: 1.5 to 3.0 %
• Recommended temperature: up to 85 °C
• Higher concentrations and temperatures may be permitted exceptionally.
• All treated surfaces should be rinsed residue-free with water after cleaning.
• Measurement of surface tension in the rinsing water is recommended as additional control.
• Can be used in combination with P3-oxonia or P3-ultrasil 02.
• Manufacturers’ limitations regarding pH and temperature stability of membranes and modules should be adhered to.

Monitoring

Concentration determination

• Titration:
  • Receiving flask: 50 ml application solution
  • Titration solution: 0.5 n HCl
  • Indicator: Phenolphthalein
  • Titration factor: 0.58
  • Formula: Volume added (ml) x 0.58 = % P3-ultrasil 110
• Conductivity:
  • Specific conductivity of P3-ultrasil 110 at various concentrations is provided in a graph and measured values list.
  • Dosage can be performed automatically conductivity-controlled.
