Compact XXL-1812

Summary

Product identification

• Model: COMPACT XXL-1812
• Configuration: Spiral Wound
• Membrane Polymer: Composite Polyamide
• Brine Spacer Material: Polypropylene

Test Conditions

Performance specifications are based on tests conducted after 30 minutes of operation, using the following conditions:

• Solution: NaCl 200 ppm
• Applied Pressure: 60 psi (4.1 bar)
• Operating Temperature: 77 °F (25 °C)
• Permeate Recovery: 15%
• pH Range: 6.5 ÷ 7.0

Product water

The following permeate flows and salt rejections are reported under the specified test conditions:

• 100 gpd (378 l/d): 98.0% nominal salt rejection (96.0% minimum)
• 150 gpd (568 l/d): 97.5% nominal salt rejection (96.0% minimum)
• 200 gpd (757 l/d): 97.0% nominal salt rejection (95.0% minimum)

Minimum permeate flow for individual elements may vary 15% below nominal.

Operating limits

• Maximum Feed Flow: 1.7 gpm (6.5 lpm)
• Chlorine Concentration: <0.1 ppm
• Feedwater SDI (15min): 3.0
• Feedwater Turbidity: 1.0 NTU
• Feedwater pH: 3.0 ÷ 10.0
• Minimum Ratio of Concentrate to Permeate Flow: 5:1 for any element
• Maximum Operating Temperature: 95 °F (35 °C)
• Maximum Pressure Drop: 10 psi (0.7 bar)
• Maximum Operating Pressure: 125 psi (8.6 bar)

The limitations shown are for general use. For specific projects, values may be more conservative to ensure best performance and longest membrane life.

Mechanical / hydraulic

• Dimensions: See the official PDF for exact tabulated values.
• Connections:
  • PRODUCT SPEED FIT (flex tube diameter 6mm)
  • BRINE FIT (flex tube diameter 6mm)
  • FEED SPEED FIT (flex tube diameter 8mm)

Notices

• The internal elements are generally dry. Wet elements contain less than 1.0% sodium meta-bisulfite and less than 10% propylene glycol solution.
• Plastic end caps close the fittings; remove before installation/use.
• The customer is fully responsible for the effects of incompatible chemicals on elements. The presence of free chlorine and other oxidizing agents will cause membrane failure, and this damage is not covered under warranty.
• Permeate obtained from the first hour of operation should be discarded.
• Avoid static permeate-side backpressure at all times.
• These membranes may be subject to drinking water application restrictions in some countries; please check the application status before use and sale.
