Flat Plate Ceramic Membranes can be widely used in mining, metallurgy, petroleum, chemical industry, textile printing and dyeing, pharmaceuticals, food and beverage, seawater desalination, municipal administration, and environmental protection.
Ceramic membranes are made of inorganic ceramic materials and include two categories: tubular ceramic membranes and flat ceramic membranes. Flat plate ceramic membranes, also known as ceramic flat membranes, serve as separation and filtration media. They have a porous structure and utilize the pressure difference across the membrane to move liquids/gases from the high-pressure side to the low-pressure side. Small molecules can pass through the membrane smoothly, while large molecules are blocked, achieving separation and filtration.
Flat Plate Ceramic Membranes can be made of ceramic materials such as alumina (Al2O3), zirconium oxide (ZrO2), and silicon carbide (SiC). Different materials have varying performance characteristics, meeting the needs of different application scenarios. The pore diameter of flat plate ceramic membranes can be selected according to specific needs to adjust the range of substances that can pass through them. Based on filtration accuracy, flat plate ceramic membranes include microfiltration membranes, nanofiltration membranes, and ultrafiltration membranes.
Flat Plate Ceramic Membranes are composed of two or more membrane layers. Because they are made of ceramic, they offer advantages such as chemical stability, high-temperature stability, and high mechanical strength. They also offer high separation efficiency and precision, low energy consumption, pollution resistance, ease of maintenance, simplicity of use, and a long service life. Flat Plate Ceramic Membranes are widely used in mining, metallurgy, petroleum, chemical industry, textile printing and dyeing, pharmaceuticals, food and beverage, seawater desalination, municipal administration, and environmental protection.
In the chemical industry, Flat Plate Ceramic Membrane is used in the chlor-alkali industry to remove calcium ions, magnesium ions, sulfate ions, and suspended solids from brine. In the pharmaceutical industry, Flat Plate Ceramic Membrane can be used for the extraction, purification, and removal of antibiotics, vitamins, amino acids, macromolecular proteins, cell wall fragments, and active ingredients in traditional Chinese medicines. In the food and beverage industry, Flat Plate Ceramic Membrane can be used to remove proteins, starch, pectin, and other substances, as well as to concentrate beverages. In the environmental protection field, Flat Plate Ceramic Membrane can remove suspended solids, microorganisms, inorganic matter, and heavy metals from wastewater.
Compared with tubular ceramic membranes, Flat Plate Ceramic Membrane has the advantages of large area, low pressure difference requirements, low energy consumption, simple peripheral supporting requirements, and low operating costs in water treatment-related fields. Compared with flat membranes and hollow fiber membranes made of polymers such as PVDF (polyvinylidene fluoride), Flat Plate Ceramic Membrane has the advantages of high operating temperature, acid and alkali resistance, organic solvent resistance, oil resistance, antioxidant and pollution resistance.
