Features

Excellent Permeability:
SWRO membranes often exhibit high permeability. Enabling the efficient flow of desired molecules through the membrane while rejecting unwanted substances.

Resistance to Fouling:
Proper design of SWRO membranes can lead to reduced fouling, as the thin active layer can discourage the accumulation of particles or contaminants on its surface.

Surface Modifications:
The active layer’s surface chemistry can be modified to enhance its selectivity and performance. Functional groups can be added to the active layer to specifically target certain substances.

Mechanical Strength:
The support layer provides mechanical strength and stability to the overall membrane structure. It prevents damage and maintains the membrane’s integrity during operation.
Type
Thin-Film Composite (TFC) Polyamide:
The dominant technology, offering high water permeability and salt rejection (around 99.8%) for seawater desalination, as noted in this ScienceDirect article.
Spiral-Wound:
Flat sheets of membrane rolled around a central tube, creating a compact, high-surface-area module that's efficient for large volumes of water, as shown in this ScienceDirect article and this YouTube video.

Applications
Water Purification and Desalination:
RO systems are extensively used to convert seawater into fresh water, a critical requirement for industries located in arid regions.
Removal of Dissolved Solids and Contaminants:
Industries often require water free from minerals and organic matter, and RO systems excel in achieving this.
Resource Recovery and Sustainability Initiatives:
Many industries use RO to recover valuable resources from wastewater, contributing to circular economy initiatives and cost savings.
