Traditional plant extraction methods often struggle with impurity retention and thermal degradation of sensitive compounds, but ceramic membrane for plant extraction technology is revolutionizing the botanical processing industry.
Ceramic membranes, with their high-temperature resistance, chemical stability, and anti-fouling properties, enable room-temperature clarification and purification of plant extracts without introducing harmful reagents. For ingredients like ginkgo biloba flavonoids and ginseng saponins, ceramic microfiltration (MF) membranes (0.1–1μm pore size) effectively trap plant fibers, colloids, and large molecular impurities, while paired nanofiltration (NF) membranes concentrate target components and remove excess salts—boosting extract purity by over 30%.
A leading traditional Chinese medicine (TCM) manufacturer adopted a ceramic membrane system for salvia miltiorrhiza extraction, cutting clarification time from 12 hours to 3 hours, improving tanshinone retention rate from 85% to 98%, and reducing wastewater discharge by 50%. The membrane’s backwashable design also extends service life, lowering long-term maintenance costs for large-scale botanical production.
Membrane separation technology is a kind of technology that uses a selectively permeable membrane as the separation medium. By applying a certain driving force (such as pressure difference, concentration difference, etc.) on both sides of the membrane, the components on the feed side can selectively permeate through the membrane, so as to achieve the purposes of separation, purification, concentration and so on.
Nowadays, more and more enterprises have keenly perceived the remarkable advantages brought by membrane technology and are actively adopting this technology to boost their own development.
In the food and beverage industry, enterprises utilize membrane technology for operations such as juice concentration and protein purification. This not only effectively preserves the flavor and nutritional components of products but also enhances product quality and extends the shelf life.
In the chemical industry, membrane technology can be applied to the recovery and separation of solvents. It improves the utilization rate of raw materials, reduces production costs, and at the same time, decreases pollutant emissions, enabling green production.
In the water treatment industry, membrane technology plays an irreplaceable role. From the in-depth treatment of industrial wastewater to the purification of drinking water, by removing impurities, heavy metal ions, and microorganisms in water, it provides enterprises with high-quality production water and effluent that meets the standards.
In the biopharmaceutical industry, membrane separation technology can accurately separate and purify biological products, ensuring the activity and purity of products and facilitating the smooth progress of new drug research and development as well as production.
It can be said that membrane technology is gradually becoming an important means for enterprises to enhance their competitiveness and achieve sustainable development.
