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.
