Operating limits
- Typical Operating Pressure: 30 - 120 psi (2.1 - 8.3 bar)
- Maximum Operating Pressure: 140 psi (9.7 bar)
- Maximum Operating Temperature: 176°F (80°C) during process
- Cleaning (CIP) Temperature Range:
- 104 - 122°F (40 - 50°C) for chlorine cleaning
- 104 - 176°F (40 - 80°C) for cleaning not involving chlorine
- Allowable pH - Continuous Operation: 2.0 - 10.0
- Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0
- Design Pressure Drop Per Element: 10-20 psi (0.7-1.4 bar)
- Maximum Pressure Drop Per Vessel: 60 psi (4.2 bar)
- Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time (including online, off-line, and during transition). Reverse pressure will damage the membrane.
Membrane Characteristics
- The membrane consists of a semipermeable polyethersulfone (PES) layer on a polyolefin backing material.
- Pure water flux of the MFK-603 membrane is 2.0-4.4 gfd/psi at 77°F (25°C).
Mechanical / hydraulic

Cleaning and Chemical Exposure
- Water Quality: Refer to KMS “Water Quality Guidelines for CIP and Diafiltration” for detailed information.
- Chlorine Exposure:
- Recommended exposure time: 30 minutes per day.
- Residual chlorine concentration during CIP: 150 ppm @ pH 10.5 or higher.
- 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 or higher.
- 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 be done only after a complete cleaning cycle and with water of acceptable quality.
- Cationic Polymers and Surfactants: Exposure to these chemicals during operation or cleaning is not recommended as MFK membranes may be irreversibly fouled, which 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.
