Mechanical / hydraulic

• Dimensions (SW30-8040):
  • A: 40 inches (1,016 mm)
  • B: 1.125 inches (29 mm)
  • C: 7.9 inches (201 mm)
• Elements fit nominal 8-inch (203 mm) I.D. pressure vessel.
• Features: Fiberglass Outer Wrap, U-Cup Brine Seal, End Cap.
• Avoid any abrupt pressure or cross-flow variations during start-up, shutdown, or cleaning.
• Feed pressure should be increased gradually over a 30-60 second time frame during start-up.
• Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds during start-up.
• Permeate obtained from the first hour of operation should be discarded.
• Keep elements moist at all times after initial wetting.
• Avoid static permeate-side backpressure at all times.
• During prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution to prevent biological growth.
