Application Of Membrane Technology In Biomedicine And Food Industry

Clarification and purification technology - ultra/microfiltration membrane system

The membranes used for clarification, purification, and separation are mainly ultra/microfiltration membranes, which are widely used in solid-liquid separation, classification of large and small molecular substances, depigmentation, product purification, oil-water separation, and other processes.

Ultra/microfiltration membrane separation can replace the natural sedimentation, plate and frame filtration, centrifuge separation, solvent extraction, resin purification, activated carbon pigment, and other processes in the traditional process.

The membrane separation components that can be used for clarification and purification technology are mainly: ceramic membrane, flat membrane, stainless steel membrane, hollow fiber membrane, roll membrane, and tubular membrane.

Features of membrane separation, clarification, and purification:

1. Absolute true solution can be obtained, and the product has good stability;

2. High filtration and separation yield;

3. Good separation effect, high product quality, and low operating cost;

4. Shorten the production cycle and reduce the production cost;

5. The process does not need to add chemicals or solvents, and does not bring in secondary pollutants;

6. Simple operation, small footprint, and low labor cost;

7. Good scalability, easy to meet the needs of industrial expansion;

8. The equipment can run automatically, with good stability and easy maintenance.

Concentration and purification technology - nanofiltration membrane system

Membrane separation technology mainly uses nanofiltration membranes with molecular weight cut-offs in the range of 100-1000 Dal in the concentration and purification process. The main feature of nanofiltration membranes is that the interception performance of divalent ions, functional carbohydrates, small molecular pigments, polypeptides, and other substances is higher than 98%, while for some monovalent ions, small molecular acids and bases, alcohols, etc. have 30-50%. It is often used in the classification of solutes, the elution of low molecular weight substances in solutions, the adjustment of ionic components, and the separation, purification, and concentration processes of substances such as concentration in solvent systems.

Nanofiltration membrane separation technology is often used to replace traditional processes such as freeze drying, thin film evaporation, ion exchange desalination, resin process concentration, and neutralization. The main membrane modules that can be used in the concentration and purification technology are roll membrane, flat membrane, and tubular membrane.

The advantages of using nanofiltration membrane separation technology to concentrate and purify:

1. The energy consumption is extremely low, saving the cost of the concentration process;

2. The process has no chemical reaction, no phase change, no other impurities, and no decomposition and denaturation of the product;

3. The purpose of concentration and purification can be achieved at room temperature, without causing damage to the active ingredients, and the process yield is high;

4. It can completely remove the salt in the product, reduce the ash content of the product, and improve the purity of the product;

5. The acid, alkali, alcohol, and other substances in the solution can be recovered;

6. The structure of the equipment is simple and compact, and the floor area is small;

7. Easy to operate, can realize automatic operation, good stability, and convenient maintenance.
