A » Spiral-wound membranes are compact and have high surface area, making them effective for large-scale desalination, while hollow-fiber membranes offer greater fouling resistance and are often used in wastewater treatment. Spiral-wound designs are generally more efficient for high-pressure applications, whereas hollow-fiber membranes are flexible and suitable for low-pressure environments, providing versatility in varying water purification processes.

A »Spiral-wound membranes have a flat sheet wrapped around a central tube, while hollow-fiber membranes consist of self-supporting tubes. Spiral-wound membranes are more prone to fouling, whereas hollow-fiber membranes offer higher surface area and are often used in ultrafiltration and microfiltration applications for water purification.
