TW30HP-4619

Summary

Product identification

FilmTec™ 4.6-inch diameter RO elements offer high quality water for sanitary applications, using the high performance TW30HP membrane, which offers excellent permeate flow and salt rejection. These elements are made with the same high quality materials of construction as larger FilmTec™ Elements used in municipal and industrial systems. For added convenience during shipping, storage and loading, these elements are available as either wet or dry products.

• Product Model: TW30HP-4619

Product water

The following typical properties are based on test conditions of 2,000 ppm NaCl, 225 psig (15.5 bar) applied pressure, 77°F (25°C), pH 8, and 8% recovery.

• Permeate Flow Rate:
  • 1,450 gpd
  • 5.49 m³/d
  • 229 l/h
• Stabilized Salt Rejection Cl⁻: 99.0%
• Minimum salt rejection for individual element is 98.0%.
• Flow rates for individual elements may vary +/-20%.

Mechanical / Hydraulic

• Element Dimensions (TW30HP-4619):
  • A: 19.20 inches (487.68 mm)
  • C: 0.75 inches (19 mm)
  • D: 4.61 inches (117 mm)
• Maximum Feed Flow Rate: 18 gpm (4.1 m³/h)
• Elements fit nominal 4.6-inch I.D. pressure vessels.

Operating limits

• Membrane Type: Polyamide Thin-Film Composite
• Maximum Operating Temperature: 113°F (45°C)
• 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))
  • Short-Term Cleaning: 1 - 13
• Maximum Feed Silt Density Index: 5
• Free Chlorine Tolerance: < 0.1 ppm (Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Oxidation damage is not covered under warranty. Removal of residual free chlorine by pretreatment prior to membrane exposure is recommended.)

Important Operating Guidelines

• Keep elements moist at all times after initial wetting.
• If operating specifications are not strictly followed, the FilmTec™ Reverse Osmosis and Nanofiltration Three-Year Prorated Limited Warranty will be null and void.
• To prevent biological growth during storage, shipping or system shutdowns, it is recommended that FilmTec™ Elements be immersed in a protective solution. The standard storage solution contains 1.0 percent (by weight) sodium metabisulfite (food grade).
• The customer is fully responsible for the effects of incompatible chemicals on elements; their use will void the warranty.
• 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.
• Permeate obtained from the first hour of operation should be discarded.
