BW60-1812-75

Summary

Product identification

The FilmTec™TW30-1812-50HR is a Residential Reverse Osmosis (RO) Element. It is a spiral-wound element featuring a polyamide thin-film composite membrane.

Key features include:

• High rejection at start-up and after stabilization.
• Up to 20% higher flow rates than competitive elements operated at the same pressure.
• Stable, reliable performance even when treating high hardness waters.
• NSF International safety certification and ability for NSF data transfer to reduce certification costs.
• Dry shipping for convenient handling and long shelf-life.

Typical Properties

Based on test conditions: 500 ppm NaHCO₃, 77°F (25°C), pH 8.0, 15% recovery and the specified applied pressure.

• Applied Pressure: 50 psig (3.4 bar)
• Permeate Flow Rate: 50 GPD (7.9 L/h)
• Typical Stabilized Salt Rejection: 99%
• Minimum Salt Rejection: 98.0%
• Permeate flows for individual elements may vary +25/-15%.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 150 psig (10 bar)
• Maximum Feed Flow Rate: 2.0 gpm (7.6 lpm)
• pH Range, Continuous Operation: 2 – 11
• Maximum Feed Silt Density Index (SDI): SDI 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. Pretreatment to remove residual free chlorine is recommended.

Mechanical / hydraulic

See the official PDF for exact tabulated values for Element Dimensions (A, B, C, D, E).

• TW30-1812 Residential Elements seal at a standard 2.0 inch – 2.05 inch I.D. within pressure vessels.

Important Information

• Keep elements moist at all times after initial wetting.
• To ease installation, it is recommended to use a lubricant safe for indirect water contact on all seals. Potential options include water, glycerin-based lubricants, and MOLYKOTE® 111 Compound.
• Rotate the element about a quarter turn to ease installation and removal. Ensure good interface between the o-rings and brine seal with their connection surfaces.
• 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.
