Advantages of roll ultrafiltration membrane: high packing density, compact structure, good flatness and low price.

Disadvantages: the manufacturing process and technology are complicated and the sealing is difficult. Easy to block, not easy to clean, can not be operated under high pressure.

Usage: Suitable for enterprises with large liquid handling capacity.

Advantages of plate-and-frame ultrafiltration membrane: the membrane module has compact and simple structure and firm scaling, and can withstand high pressure better than other membrane modules.

Disadvantages: the use cost of the device is high, and the poor flow state is easy to cause more serious concentration polarization. The membrane element is blocked, so it is not easy to clean, and the packing density of the membrane becomes smaller.

Usage: suitable for small enterprises dealing with liquids.
