Product categories

The STRO element is an open-channel RO element: a spiral wound structure with more membrane area, combined with a special open feed spacer that lowers flow resistance and concentration polarization. It is designed for high-salt and high-TSS wastewater where standard RO elements foul quickly, and it can replace equivalent Nanostone elements.

Key features

  • High-strength design, up to 120 bar maximum operating pressure
  • Open feed spacer with low flow resistance
  • Spiral wound structure with more membrane area than disc tube modules
  • High recovery with low energy cost
  • Easy cleaning and maintenance, long membrane life

Practical applications

Landfill leachate

RO stage for leachate with high salinity and solids.

High-salt industrial wastewater
