Compared with the traditional separation technology, why the use of membrane separation technology can reduce the separation process energy consumption

I. The advantages of membrane separation technology compared with traditional separation technology are as follows:

1. At room temperature:

Loss of active ingredients is very small, especially suitable for heat-sensitive substances, such as antibiotics and other pharmaceuticals, fruit juices, enzymes, proteins, separation and concentration

2. No phase change:

Maintaining the original flavor, energy consumption is very low, and the cost is about The cost is about 1/3-1/8 of evaporation concentration or freezing concentration

3, no chemical change:

Typical physical separation process, without chemical reagents and additives, the product is not contaminated

4, good selectivity:

Can be separated at the molecular level, and it has the excellent performance that can't be replaced by the common filter material

5, adaptable:

5, the size of the process, the size of the process, the size of the process and the concentration of the protein, and the concentration of the protein.

Treatment scale can be large or small, can be continuous or intermittent, simple process, convenient operation, easy automation

6, low energy consumption:

Only need electrical energy drive, energy consumption is very low, its cost is about 1/3-1/8 of the evaporation and concentration or freezing concentration

The second basic introduction of the membrane separation technology:

Membrane separation was in the early 20th century, the 1960s, the 20th century, the 1960s, the 1960s and the 1990s, and the 1990s, the 1990s and the 1990s, the 1990s and the 1990s. Membrane separation is in the early 20th century, the 1960s after the rapid rise of a new separation technology. Membrane separation technology due to both separation, concentration, purification and refining functions, but also high efficiency, energy saving, environmental protection, molecular filtration and filtration process is simple, easy to control and so on, therefore, at present has been widely used in food, medicine, biology, environmental protection, chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionic and other fields, resulting in huge economic and social benefits, has become one of the most important means in today's separation science. It has become one of the most important means of separation science today.
