TW30HP-4641

Summary

Product identification

FilmTec™ 4.6-inch diameter RO elements offer high quality water for sanitary applications, using the high performance TW30HP membrane. These elements are available as either wet or dry products.

• Membrane Type: Polyamide Thin-Film Composite

Product water

The TW30HP-4641 element provides the following typical performance:

• Product Water Flow Rate: 5,200 gpd (19.68 m³/d, 820 l/h)
• Applied Pressure: 225 psig (15.5 bar)
• Stabilized Salt Rejection Cl⁻: 99.0%

Test Conditions:

• Feed water: 2,000 ppm NaCl
• Temperature: 77°F (25°C)
• pH: 8
• Recovery rate: 15% (for TW30HP-4641)

Notes:

• Minimum salt rejection for individual element is 98.0%.
• Flow rates for individual elements may vary +/-20%.
• Permeate obtained from the first hour of operation should be discarded.

Operating limits

• Maximum Operating Pressure: 600 psi (4.1 MPa)
• Maximum Pressure Drop: 15 psi (1.0 bar)
• pH Range - Continuous Operation: 2 - 11 (Maximum temperature for continuous operation above pH 10 is 95°F (35°C))
• pH Range - Short-Term Cleaning: 1 - 13

Feed water

• Maximum Feed Silt Density Index: 5
• Free Chlorine Tolerance: < 0.1 ppm

Mechanical / hydraulic

The TW30HP-4641 element has the following characteristics:

• Maximum Feed Flow Rate: 18 gpm (4.1 m³/h)
• Elements fit nominal 4.6-inch I.D. pressure vessels.

Dimensions (Inches / mm):

• A: 41.31 (1,049)
• B: 2.19 (56)
• C: 0.75 (19)
• D: 4.61 (117)

Important Operating Information:

• Keep elements moist at all times after initial wetting.
• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
