RO-390-FF

Summary

Product identification

FilmTec™ Sanitary RO Membrane Elements are reverse osmosis (RO) elements designed for food and beverage water applications. They feature a sanitary, high-rejection FT30 reverse osmosis membrane.

These elements are suitable for processing various streams, including bottled water, juice, soft drinks, and non-dairy milk products. Their full-fit configuration minimizes stagnant areas, which is optimal for sanitary design requirements. All components comply with FDA indirect food contact regulations.

For the RO-390-FF model:

• Part Number: 116314 / 100608
• Active Area: 390 ft² (36.23 m²)
• Stabilized Permeate Flow Rate: 13,700 gpd (51.8 m³/d)
• Typical Stabilized Salt Rejection: 99.5%

Mechanical / hydraulic

Element Dimensions (RO-390-FF):

• A (length): 40.00 in (1,016 mm)
• B (inner diameter): 1.125 ID (28.58 mm)
• C (outer diameter): 7.9 in (200 mm)

General operating guidelines:

• Maximum pressure drop across an entire pressure vessel (housing) is 60 psi (4.1 bar).
• Avoid permeate-side backpressure at all times.
• Feed pressure should be increased gradually over a 30-60 second time frame during start-up.
• Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.

Operating limits

• Membrane Type: Thin-Film Composite
• Maximum Operating Temperature: 113ºF (45ºC)
• Maximum Operating Pressure: 600 psi (41 bar)
• Maximum Differential Pressure: 15 psi (1.0 bar)
• Maximum Feed Turbidity: 1 NTU
• Free Chlorine Tolerance: Below Detectable Limits
• pH Range (Continuous Operations): 3 – 10
• pH Range (Short-Term Cleaning, 30 min): 1 – 12
• Maximum Feed Silt Density Index (SDI): 5

General information

• Keep elements moist at all times after initial wetting.
• To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
• The use of this product does not necessarily guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
