SIC ceramic filter membrane – Pure SIC filter membrane

Water treatment membranes made of silicon carbide possess characteristics such as high hardness, high temperature resistance, acid and alkali corrosion resistance, high flux, and high hydrophilicity. Their flux can reach 100 times that of traditional organic membrane materials and 3-5 times that of ordinary ceramic membranes.

Silicon carbide membranes are manufactured using a 2300℃ sintering process. During sintering, the sintering necks between silicon carbide clusters undergo a solid-gas-solid phase transition, resulting in an opening ratio exceeding 45%. The formed filtration channels have strong connectivity, and combined with the excellent hydrophilicity of silicon carbide itself (contact angle of only 0.3°), this allows for a pure water flux of up to 3000 L/h, while also exhibiting hydrophilic and oleophobic properties.

The isoelectric point of the silicon carbide film is around pH 3, and the surface of the film can maintain negative charge over a wide pH range, improving its pollution resistance.

Excellent chemical stability, capable of working in extreme environments (pH range of 0-14); Rich cleaning plans can be developed based on the characteristics of pollution factors; Oxidants are fully tolerant, including ozone and hydroxyl radicals.

The unique technology of the company's product is the integrated silicon carbide film, which refers to the silicon carbide ceramic film sintered together with the silicon carbide support body and film layer. Its advantages lie in:

The membrane layer is not easily detached, greatly improving the lifespan of the membrane body on top of the foundation;

More suitable for backwashing process, making membrane pores less prone to clogging, with a service life of up to fifteen years.
