Braid-Reinforced Hollow Fibre Membranes: Why MBR Uses Them and How They Are Made

At a glance. A braid-reinforced fibre is a polymer membrane coated onto a braided tube. A Tech Inc. Braid-Reinforced Hollow Fibre Membrane Line makes them continuously.

Why use a braid

• Very high tensile strength.

• Survives aeration, backwash and cleaning.

• Long life in submerged MBR.

How they are made

1. Braid unwinds from a creel under tension.

2. An annular die coats it with metered dope.

3. Coagulation forms the membrane.

4. Washing removes solvent before winding.

Frequently asked questions

Can the same line make unsupported fibres? No; that needs a spinning line with bore fluid.
