Nominal Specifications

Operating limits

• Typical Operating Pressure: 15 - 30 psi (1.0 - 2.1 bar)
• Maximum Operating Pressure: 140 psi (9.7 bar)
• Maximum Operating Temperature: 122°F (50°C) during process
• Cleaning (CIP) Temperature Range:
  • 104 - 122°F (40 - 50°C) for cleaning with chlorine
  • 104 - 176°F (40 - 80°C) for cleaning without chlorine
• Allowable pH - Continuous Operation: 2.0 - 10.0
• Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0

Water Quality for Cleaning & Diafiltration

Refer to KMS “Water Quality Guidelines for CIP and Diafiltration” for more detailed information.

Chlorine and Chemical Exposure

• Adherence to cleaning and sanitizing procedures, including chemical concentrations, pH, temperature, and exposure time, is necessary for maximum element life.
• Recommended chlorine exposure time is 30 minutes per day.
• Residual chlorine concentration during CIP should be 150 ppm @ pH 10.5-11.0. Chlorine concentration should never exceed 200 ppm.
• Chlorine should only be added to the cleaning solution after the pH has been adjusted to 10.5-11.0.
• Maximum cleaning temperature is 122°F (50°C) when chlorine is used.
• Maximum cleaning temperature is 176°F (80°C) for cleaning cycles not involving chlorine.
• Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Sanitizing should only be done after a complete cleaning cycle and with water of acceptable quality.
• Cationic Polymers and Surfactants: Dairy-Pro® MF-0.1 membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty.

Lubricants

For module installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the element and will void the warranty.
