Aqualast 1812 HR

Summary

Product identification

The FilmTec™ Aqualast™ 1812-HR Element is a residential reverse osmosis (RO) element, designed as a spiral-wound element with a polyamide thin-film composite membrane.

Key features include:

• Anti-scaling design for stable, reliable performance under high water recovery operation.
• Long element life in high hardness waters.
• Up to 40% reduction in salt passage compared with FilmTec™ Aqualast™ 1812, including nitrate rejection.
• NSF International safety certification.
• Dry shipping for convenient handling and long shelf-life.

Product water

The Aqualast™ 1812-HR element exhibits the following typical properties based on test conditions of 250 ppm NaCl, 77°F (25°C), pH 8.0, 15% recovery, and specified applied pressure:

• Applied Pressure: 50 psig (3.4 bar)
• Permeate Flow Rate: 75 GPD (12 L/h)
• Typical Stabilized Salt Rejection: 99%
• Minimum Salt Rejection: 97.0%

Permeate flows for individual elements may vary ±20%.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Note: 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

Mechanical / hydraulic

The Aqualast™ 1812-HR element dimensions are:

• A: 11.74 in. (298 mm)
• B: 0.875 in. (22.2 mm)
• C: 0.68 in. (17 mm)
• D: 1.75 in. (44.5 mm)
• E: 9.4 in. (239 mm)

The element seals at a standard 2.0 inch – 2.05 inch I.D. within pressure vessels.

Additional important information

• Elements should be kept moist at all times after initial wetting.
• For ease of installation, using a lubricant safe for indirect water contact on all seals (e.g., water, glycerin-based lubricants, MOLYKOTE® 111 Compound) is recommended.
• Rotating the element about a quarter turn can ease installation and removal. Ensure good interface between the O-rings and brine seal with their connection surfaces.
• Systems using these elements should rinse them for 24 hours prior to first use to meet NSF/ANSI 58 Standard.
• The use of this product does not necessarily guarantee the removal of cysts and pathogens from water; effective reduction depends on the complete system design and its operation and maintenance.
• Permeate obtained from the first hour of operation should be discarded.
• If operating limits and guidelines are not strictly followed, the Limited Warranty will be null and void.
