Applications: Chemical Industry | Dairy, Food & Beverages | Waste Water Treatment

ST modules are ideal for various critical applications:

ST module: Developed for difficult conditions
Our ST membrane modules are tailored to feed streams with a high degree of hardness and significant suspended solids content and have excellent anti-fouling properties, making them perfect for treating heavily contaminated wastewater.

  • Landfill leachate treatment
  • Chemical and Wastewater Desulfurization
  • High Solids Applications
  • Offshore Seawater Desalination
  • Zero Liquid Discharge/Reduction of Industrial Wastewater
  • High pressure F&B Applications
What are the reasons for DT / ST Reverse Osmosis Modules?
  • High-quality diaphragm
    Delivers consistent performance with high flux and rejection rates.
  • Innovative design
    State-of-the-art design, including the next generation deflector for improved robustness and increased turbulence.
  • Improved efficiency
    Radially symmetrical flow improves filtration efficiency and uniformity, ideal for high-purity processes.
  • Extended service life of the diaphragm
    Reduces operating costs through extended service life and lower maintenance costs.
  • High packing density
    The ST design maximizes the membrane area and improves performance.
  • Excellent anti-fouling properties
    The optimized flow pattern minimizes dead zones and ensures efficient operation.
  • Versatility in pressure levels
    Enables a range of pressure levels, up to 160 bar, to meet specific requirements.
  • High specific output
    Up to twice the output of normal SWRO seawater elements.

Simple operation and maintenance: Simplifies daily operation and offers convenience and reliability.
