Applications of Ceramic Membrane Separation Technology

Ceramic Membrane Separation technology uses ceramic membranes as a form of solid-state membranes. These membranes are ceramic filter separation materials, supported by porous ceramic substrates and featuring microporous ceramic membrane layers. They are characterized by tubular and multi-channel structures, with the tube walls densely packed with micropores.

Application of Ceramic Membrane Separation Technology in Water Treatment

In water treatment applications, ceramic membrane separation technology began in the early 1980s. The advantage of using microporous ceramic membranes for water treatment is that they ensure better and more reliable water quality, do not require the use of chemicals, and are suitable for high-value-added products.

Application of Ceramic Membrane Separation Technology in Desalination

Ceramic membrane separation technology utilizes ceramic membranes characterized by narrow pore size distribution, high porosity, thin separation layers, and low filtration resistance. Additionally, they offer a high processing capacity per membrane surface area, resulting in high water production capacity. The ceramic membrane's stable chemical properties allow for long-term stable operation in seawater, making it suitable for desalination pretreatment.

Application of Ceramic Membrane Separation Technology in Oily Wastewater Treatment

Oily wastewater comes from various sources and is characterized by difficulty in degradation and ease of emulsification, making conventional treatment methods less effective. Ceramic membrane separation technology, on the other hand, can treat industrial oily wastewater to meet the requirements for injection or discharge water quality standards.

Application of Ceramic Membrane Separation Technology in Chemical and Petrochemical Wastewater Treatment

The chemical and petrochemical industries often produce wastewater containing strong acids, bases, or corrosive particles. For such wastewater, ceramic membrane separation technology, due to its excellent chemical stability, offers unique advantages in treatment.

Ceramic Membrane Separation Technology in Domestic Sewage Treatment

Domestic sewage represents a significant proportion of various water pollution sources. This type of sewage has a low pollution level but a large volume. Treating and recycling it can protect freshwater resources and improve water utilization rates, especially in water-scarce areas. Using ceramic membrane bioreactors to treat domestic sewage results in stable and effective water quality outcomes.

Application of Ceramic Membrane Separation Technology in Traditional Chinese Medicine (TCM) Production

Ceramic membrane technology, tailored for the unique characteristics of TCM production, has developed a series of new integrated membrane separation processes based on inorganic ceramic membrane separation equipment. These processes overcome the limitations of using organic membranes alone in TCM production, such as quick flux decline, difficulty in cleaning, and short membrane lifespan. These advancements have yielded significant economic and social benefits.

Using ceramic membranes for effective separation and purification of TCM extracts can filter out macromolecular substances like proteins, starches, pectins, tannins, and microorganisms, reducing the loss of water-soluble active ingredients while ensuring minimal retention of TCM active ingredients.

Applying ceramic membrane separation technology for fine filtration of medicinal liquids to remove tannins, starches, and impurities can replace primary alcohol precipitation, reducing the number of alcohol precipitation steps and achieving non-alcoholic production. This substitution eliminates the traditional water extraction and alcohol precipitation processes, shortens the production cycle, and achieves the goals of clear medicinal liquids and non-alcoholic production.
