In today's increasingly serious environmental pollution, sewage treatment has become an important measure to ensure the safety of water resources and the ecological environment. Among the many sewage treatment technologies, the SIC membrane filter, with its unique advantages and wide range of application scenarios, has become a bright pearl in the field of sewage treatment.
The SIC membrane filter, the full name of which is the silicon carbide ceramic membrane filter, is a microfiltration and ultrafiltration product made of silicon carbide (SIC), the inorganic carbon material with the best hydrophilicity. This filter has excellent anti-fouling ability, extremely high filtration flux, super strong chemical stability and great mechanical strength, and is a leader in the field of sewage treatment. The membrane core structure adopts a honeycomb structure design, which not only has high mechanical strength, high packing density and good sealing performance, but also is convenient for installation and maintenance, greatly reducing the operation cost and maintenance difficulty.

The principle of the SIC membrane filter is mainly to effectively intercept impurities such as suspended solids, particulate matter and grease in the sewage through its microfiltration and ultrafiltration functions, so as to achieve the purpose of purifying the water quality. Its filtration pore size is extremely small, and the absolute accuracy can reach below 1.0μm (filtration pore size 40nm), which can ensure the high quality of the effluent water. At the same time, due to the good hydrophilicity of the SIC material and the contact angle with water is only 0.3, it has extremely strong anti-oil pollution ability and can maintain high-efficiency filtration performance even in sewage with high oil content.
In addition to the excellent filtration performance, the SIC membrane filter also has many unique characteristics. First, its water flux is high, which is 3-4 times that of the traditional ceramic membrane and can greatly improve the sewage treatment efficiency. Secondly, the dynamic continuous membrane regeneration technology is adopted, with good membrane regeneration performance and long service life, reducing the frequency and cost of replacing the filter membrane. In addition, the SIC membrane filter also has excellent chemical stability and high pressure and temperature resistance, and can operate stably for a long time in the harsh sewage environment, and the maximum use temperature can reach 800°C.
In terms of application scenarios, due to its unique advantages and characteristics, the SIC membrane filter is widely used in the tail-end treatment processes in the fields of oilfield production reinjection water treatment, petrochemical sewage advanced treatment, metallurgy, textile and other industries' sewage advanced treatment. In the oilfield production reinjection water treatment, the SIC membrane filter can effectively remove impurities such as suspended solids, particulate matter and grease in the sewage to ensure that the quality of the reinjection water meets the standards and avoid polluting the formation. In the petrochemical sewage advanced treatment, the SIC membrane filter can further purify the sewage, remove pollutants such as difficult-to-degrade organic matter and inorganic salts, improve the effluent water quality, and realize the达标排放 or reuse of the sewage. At the same time, in the sewage advanced treatment of metallurgy, textile and other industries, the SIC membrane filter also plays an important role, providing strong support for the sustainable development of these industries.
To sum up, the SIC membrane filter, with its unique advantages and wide application scenarios, has shown great potential and value in the field of sewage treatment. With the progress of science and technology and the improvement of environmental awareness, it is believed that the SIC membrane filter will be more widely applied and promoted in the future and make greater contributions to the environmental protection cause of mankind.
