SG30LE-440i

Summary

Product identification

The FilmTec™ SG30LE-440i is an 8-inch Semiconductor Grade Reverse Osmosis Element designed for ultrapure water (UPW) systems. It features high overall rejection, improved rejection of lower molecular weight organic compounds and silica, and an accelerated TOC rinse down profile. This element is primarily intended for polishing use in newer UPW equipment, offering benefits such as lower capital cost and reduced energy consumption.

The product incorporates iLEC™ interlocking endcaps, which help reduce system operating costs, minimize the risk of O-ring leaks, prevent the generation of small particles that could degrade water quality, and eliminate the need for lubricants.

Product water

• Permeate Flow Rate: 10,000 gpd (38 m³/d)
  • Conditions for stated flow rate: 107 psi (0.74 MPa), 77°F (25°C), and 15% recovery.
  • Flow rates for individual elements may vary but will not be more than 15% below the value shown.

Important Operating Information

• Elements must be kept moist at all times after initial wetting.
• To prevent biological growth during prolonged system shutdowns, elements should be immersed in a preservative solution.
• Customers are fully responsible for the effects of incompatible chemicals and lubricants on elements.
• Avoid static permeate-side backpressure at all times.
• Proper start-up procedures are essential to prepare membranes for service and prevent damage from overfeeding or hydraulic shock. Refer to application literature for start-up sequences.
• Any concentrate or permeate obtained from the first hour of operation should be discarded.
• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water; effective removal depends on complete system design, operation, and maintenance.
