This product is an innovative product that breaks the boundary between the application scenarios of inorganic and organic membranes. It combines the advantages of ceramic membrane products being sturdy and durable, as well as high filling density of organic membrane products. The usage method is similar to that of organic column membranes, making up for the shortcomings of ultrafiltration membrane technology such as high inlet water quality requirements, high backwash water consumption, and the risk of wire breakage. It can improve the water yield of ultrafiltration systems and reduce chemical cleaning costs.

The silicon carbide ceramic core is composed of 13 hexagonal tubular membrane products spliced together. The unique structural design makes the hydraulic distribution of the water production and backwashing channels of each tubular membrane product more uniform, and the backwashing recovery effect is outstanding.

• Competitive investment costs and excellent lifecycle

• Compatible with traditional organic membrane ultrafiltration systems

• The core material silicon carbide is a more advanced and ideal ceramic membrane material compared to alumina, with better hydrophilicity, higher porosity, excellent cleaning recovery, and no fear of oil pollution.

Characteristics of silicon carbide tubular membrane
The silicon carbide membrane is produced by recrystallization process, with a sintering temperature of 2400 ℃. During the sintering process, the sintering neck between the silicon carbide aggregates undergoes a phase transition from solid to gas to solid, with an opening rate of over 45%. The formed filter channel has strong connectivity, coupled with the inherent hydrophilicity of the silicon carbide material (contact angle only 0.3 °), resulting in a pure water flux of up to 3200LMH, and is hydrophilic and oleophobic.
The isoelectric point of the silicon carbide membrane is around pH 3, and the surface of the membrane can maintain being negatively charged over a wide pH range, improving its pollution resistance.
Excellent chemical stability, capable of working in extreme environments (pH range 1-14); a variety of cleaning plans can be developed based on the characteristics of pollution factors; Oxidants are fully tolerant, including ozone and hydroxyl radicals.

Silicon carbide flat sheet membrane is made by sintering high-purity silicon carbide powder at high temperature, and is currently the membrane material with the best hydrophilicity and anti pollution ability.

• The membrane surface with high negative charge can ensure excellent pollution resistance across a wide pH range;

• Ideal operating conditions - when the PAC addition makes the pH less than 6, the membrane surface can maintain a negative charge of -25~-30 millivolts, making it difficult for soluble organic carbon and transparent exopolymer particles to adhere to the membrane surface;

• It is easy to remove negatively charged substances in water from the membrane surface, such as bacteria, algae, MLSS, transparent exopolymer particles, and oil substances.
