The multi-function membrane separation experiment system is a small membrane separation experiment system designed by our company according to the characteristics of universities, research institutes and enterprise r&d centers. This system has the characteristics of small area, convenient transportation, high operating pressure, small circulation volume, strong universality, simple operation and so on, especially suitable for the small amount of material units or individuals to carry out r & d verification experiments.

The equipment parameters

Membrane is a kind of polymer material with special selective separation function, which can separate the fluid into two parts that are not connected, so that one or several substances can pass through, and the other substances can be separated. Membrane separation technology with its high efficiency, energy saving, environmental protection and high precision separation characteristics, has been widely used in medicine, chemical industry, electronics, food, environmental protection and other fields, has become one of the major industrial technologies in the 21st century.

Membrane separation method refers to the method of separating solid from liquid and molecule from molecule according to cross-flow filtration according to the principle of sieving with pressure as the driving force and semi-permeable membrane as the filtration layer, according to the molecular size, configuration and electrical polarity of the material. The core of membrane separation is the membrane itself, which needs to be semi-permeable, that is, able to pass through one substance and obstruct another.

Membrane technology and membrane separation and concentration technology based on polymer materials science have some advantages that traditional separation and concentration technology cannot compare with:

High separation precision, good separation and concentration effect, high work efficiency;

Pure physical process, no chemical reaction, no secondary pollution;

Cross-flow operation process, better solve the problem of pollution blockage, prolong the cleaning cycle;

The membrane module has a large filling area, a large amount of infiltration, and a small footprint, which can reduce the investment of hardware facilities.

The separation process has no phase transition, low energy consumption and meets the requirements of clean production for energy saving and emission reduction.

The membrane can be cleaned and reused repeatedly with a service life of 2-3 years to reduce the consumption cost.

High degree of automation, reduce labor intensity and reduce labor cost;

Scope of business

Ceramic membrane, stainless steel membrane, organic tube membrane, roll membrane, reverse osmosis membrane, microfiltration/ultrafiltration/nanofiltration technology and equipment

Application field

1. Biological fermentation

Degerming, clarifying, purifying and concentrated desalting of fermentation liquor;

2. Plant extraction

Traditional Chinese medicine plant is leaching solvent into the medicinal materials, transfer the effective components from the solid phase to liquid phase separation process, traditional process of low accuracy, high solvent consumption, high cost of enrichment process, such as the introduction of advanced membrane system provides the separation and purification technology for its industrial production, energy saving, water saving and emissions reduction, reliable means of clean and environmental protection.

Problem solving:

Purification of impurities: remove the soluble impurities in the liquid after centrifuge separation, such as colloids, proteins, tannins and other impurities, improve the quality, with a high degree of clarity, macromolecules have a good intercession effect.

Energy saving: reduce energy consumption. Membrane concentration costs only 2-10 yuan/ton of water, while traditional concentration costs 80-100 yuan/ton of water.

Recycling: membrane concentrated dialysis water can be reused to the extraction process to improve the utilization of water resources.
