Structure and Principles of Ceramic Membrane Filters

Ceramic membrane filters are filtration devices that use microporous ceramic membranes as the filtering medium. Their main components include the feed pipe, filtration membrane, discharge pipe, and gas discharge valve. When the material to be filtered passes through the ceramic membrane, the membrane's micropores filter out impurities and suspended solids, without affecting the passage of purified substances.

Working Principle of Ceramic Membrane Filters

Ceramic membrane water treatment, as an efficient and environmentally friendly technology, has gradually gained a foothold in the water treatment field in recent years. Ceramic membranes are inorganic membranes with a narrow pore size distribution, utilizing nanometer-level membrane separation technology. During water treatment, ceramic membranes separate different substances through selective permeability, based on the physical action of the membrane. When polluted water flows through the membrane channels, "crossflow filtration" is achieved. Under pressure, toxic and harmful compounds, ammonia nitrogen, microorganisms, bacteria, and pathogens are retained by the membrane, while purified water is produced on the other side. This method does not require the addition of chemicals, ensuring the safe quality of the treated water.

Advantages of Ceramic Membrane Filters

First, ceramic membrane filters have low energy consumption, low failure rates, high mechanical strength, and long service life. This makes ceramic membrane equipment more stable and reliable during operation, reducing maintenance costs. Additionally, ceramic membranes have a small footprint, are easy to clean and maintain, providing convenience for the installation and operation of water treatment equipment. Furthermore, ceramic membranes offer excellent resistance to chemical corrosion and high temperatures, allowing stable operation in harsh environments.

Operation Method of Ceramic Membrane Filters

Installation

• Ensure the environment around the ceramic membrane filter is clean and prepare the cleaning tools and relevant equipment.

• Turn on the power and start the ceramic membrane filter, waiting for the membrane reactor to stabilize and reach the set thermal stability temperature.

• Select appropriate feed and discharge pipes, then open the feed valve.

• Inside the filtration equipment, maintain the set flow rate when the required pressure differential is achieved.

Cleaning

• Determine the cleaning method and time based on the usage status of the ceramic membrane filter, and then proceed with the cleaning according to the operating procedures.

• Before cleaning, close the feed valve and discharge any remaining substances and gas in the pipes.

• Inject the appropriate cleaning solution into the feed pipe, adjusting the flow and pressure of the cleaning solution according to the process.

• Start the cleaning program and follow the operating sequence to execute the cleaning procedure.

• After cleaning, close the discharge valve and discharge the cleaning solution from the pipes.

Maintenance

• Regularly check and clean the various parts of the ceramic membrane filter.

• Keep the environment around the ceramic membrane filter clean to avoid contamination and damage.

• Regularly replace the filter membranes inside the ceramic membrane filter to ensure filtration efficiency.

• Periodically check the overall performance and working condition of the ceramic membrane filter, making adjustments and repairs as needed.

• Ensure the normal operation and service life of the ceramic membrane filter to improve filtration efficiency and economic benefits.
