Features

• Delivers high boron rejection to help meet WHO and other drinking water standards.
• Offers high performance over its operating lifetime without the use of oxidative post-treatments, contributing to durability and effective cleaning over a wide pH range.
• Automated, precision fabrication with a greater number of shorter membrane leaves reduces overall fouling effects and maximizes membrane efficiency.

Operation Guidelines

• Proper start-up procedures are essential to prepare membranes and prevent damage from overfeeding or hydraulic shock.
• Avoid abrupt pressure or cross-flow variations during start-up, shutdown, cleaning, or other sequences.
• During start-up, a gradual change to operating state is recommended:
  • Feed pressure should be increased gradually over a 30-60 second timeframe.
  • Cross-flow velocity should be achieved gradually over 15-20 seconds.
• Permeate obtained from the first hour of operation should be discarded.
• Keep elements moist at all times after initial wetting.
• During prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution to prevent biological growth.
• Avoid permeate-side backpressure at all times.
