Question

What is an membrane what are the uses of membrane and the advantages and disadvantage

Answer 1

Membrane:

✴A membrane is a thin sheet of tissue or layer of cells acting as a boundary, lining, or partition in an organism.

Advantages

✴Membranes can be manufactured in a uniform and highly precise manner.

✴ The processes are prone to membrane fouling effects which lead to decrease in permeate flux.

✴Expensive cleaning and regeneration schemes may be necessary. The high flow rates used in cross-flow feed can damage shear sensitive materials.

Disadvantages

✴The processes are prone to membrane fouling effects which lead to decrease in permeate flux.

✴ Expensive cleaning and regeneration schemes may be necessary.

• Membrane processes are able to recover minor but valuable components from a main stream without substantial energy costs.
• Membrane processes are potentially better for the environment since the membrane approach require the use of relatively simple and non-harmful materials
