Romicon 3" PM5 Hollow Fiber

Summary

Product identification

ROMICON® 3” HOLLOW FIBER CARTRIDGES are 3-inch diameter hollow fiber ultrafiltration cartridges designed for filtration of process streams within a separation range of 5,000 to 500,000 dalton. These crossflow-type filters provide stable productivity, ease of cleaning, and reliable operation by minimizing solids cake buildup.

• Membrane Polymer: Polysulfone
• Housing Construction: Polysulfone
• Seal/Potting Material: Proprietary Epoxy Compound
• Storage Solution: Glycerin

Options

• Lumen size: 20 mil (0.5 mm), 43 mil (1.1 mm), 60 mil (1.5 mm), 75 mil (1.9 mm), 106 mil (2.7 mm)
• Membrane Type: PM5, PM10, PM30, PM50, PM100, or PM500
• Special Construction for Specific Applications:
  • Vinegar Filtration: Selected PM50 and PM500 cartridges are available.
  • Citrus Filtration: Selected PM10, PM50 and PM500 cartridges are available.
  • ROMIPRO™ Cartridges: Selected cartridges of all membrane types are available with components that have passed USP Class VI test guidelines.

Cartridge Availability and Membrane Area

Available Membrane Area [ft² (m²)] corresponding to the listed fiber diameters: 53 (4.9), 25 (2.3), 25 (2.3), 21 (1.9), 16 (1.5).

Product Nomenclature

The product nomenclature follows a seven-field structure:

• Field 1: HF – Hollow fiber cartridge
• Field 2 (optional): Market or application designation
• Field 3: Cartridge diameter times 10 in inches
• Field 4: Cartridge length in inches
• Field 5: Active membrane area in ft²
• Field 6: Fiber diameter in mils (1000 mil = 1 inch)
• Field 7: Molecular Weight Cutoff divided by 1000 in Daltons

Example: A 5-inch diameter by 43-inch long hollow fiber cartridge for vinegar filtration, utilizing fibers with a diameter of 106 mil and 500,000 Dalton, has an active membrane area of 40 ft².

Operating limits

• Maximum Operating Pressure: 40 psi (2.8 bar), or 100 psi if the permeate side is pressurized. Actual operating pressure depends on feed stream, recovery, and temperature conditions.
• Maximum Transmembrane Pressure: 35 psi (2.4 bar)
• Maximum Operating Temperature (at pH 6.0): 140°F (60°C)
• Maximum Permeate Side Back Pressure: 20 psi (1.4 bar) at any time, including backflush.
• Maximum Differential Pressure Feed Side (per cartridge): 30 psi (2.1 bar)
• Allowable pH: 1.5 – 13.0 @ 130°F (54°C)
• Maximum Cleaning Temperature: 130°F (54°C)
• Maximum Total Chlorine (During Cleaning): 200 ppm @ pH 10-10.5, 130°F (54°C); 0 ppm @ pH < 9.5.

Consult KMS Process Technology Group for specific applications.

Cleaning Guidelines

• pH for Cleaning: Allowable range is 1.5 to 13.0. Refer to "KMS Water Quality Guidelines" for more detailed information.
• Exposure to Chemical Oxidants: Not recommended for daily use but may be necessary for thorough cleaning and sanitization. Potassium metabisulfite (without catalysts like cobalt) is the preferred chemical to eliminate residual chlorine or similar oxidizers before processing liquid.
• Lubricants for Installation: Use only water or glycerin. Petroleum or vegetable-based oils/solvents may damage the cartridge and void the warranty.
