Materials are supporting the iteration and evolution of membrane separation products, while the structure of membrane components is also constantly innovating and breaking through. The boundary between the application scenarios of organic and inorganic membranes is gradually becoming blurred.
Silicon carbide ceramic membrane is a high precision microfiltration & ultrafiltration grade membrane separation product made of high purity silicon carbide fine powder through recrystallization sintering technology.
It has high flux, high corrosion resistance, easy cleaning, and long service life.
At present, the highest filtration precision can reach 20nm. It uses unique design and manufacturing processes to combine inert silicon carbide materials and screened non-ceramic materials to form the inherently strong and durable membrane. This guarantees its long term service and durability in harsh environments.
It uses equivalent or lower investment cost compared to organic ultrafiltration membranes to create SiC carbide inorganic ultrafiltration products that are more reliable, easier to operate, and have longer service life, meanwhile, achieve the lowest total life cycle cost in the long time service.
● 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.
★High flux, 3-10 times compared to organic membranes;
★Small footprint, saving land;
★Water consumption for backwashing is reduced by more than 50%;
★Chemical tolerance, capable of working in pH 0-14 environment, acid and alkali resistant;
★The service life is 2-10 times longer than the organic membranes, lower replacement cost;
★Allow for strict chemical cleaning, high flexibility in cleaning, and the flux is easy to recover after cleaning;
★The performance is easy to recover after pollution and blockage, eliminating the cost of membrane replacement caused by unexpected failures;
★Low system preprocessing requirements, reducing total system investment and operating costs;
★Higher Pressure differences between membranes allowed, so low temprature source water flux increases;
★No membrane broken problem, and less maintainance required.
Washing and concentration of nano powder
Oil-water separation (oilfield reinjection water, liquid hazardous waste regeneration)
Material separation
Solid liquid separation with high solid content (mine water, biological fermentation broth)
Solid liquid separation in harsh chemical environment (acid purification, nano powder catalyst recovery)
Good chemical stability
SiC Tubular Membrane has excellent chemical stability and can withstand strong acids, strong alkalis and all organic solvents. This means that a variety of chemical cleaning agents can be used for cleaning, thereby effectively removing pollutants on the membrane surface and restoring the initial flux of the membrane.
Combination of physical cleaning and chemical cleaning
Silicon carbide membrane can be cleaned by physical methods such as backwashing, low-pressure and high-flow cleaning, electrocleaning, ultrasonic cleaning, etc., as well as chemical methods such as chemical immersion and recirculation cleaning. These methods can effectively remove pollutants that block the membrane pores, thereby restoring the membrane flux.
High temperature resistance
Silicon carbide membrane has good thermal stability and thermal shock resistance, and can operate stably under high temperature conditions. This allows the use of high-temperature water or other cleaning fluids during the cleaning process to improve the cleaning efficiency and thus improve the recovery rate of membrane flux.
Hydrophilicity and oleophobicity
Silicon carbide membranes have high hydrophilicity, which makes the membrane surface less likely to be contaminated by oil substances in applications such as oil-water separation, thereby reducing the difficulty and frequency of cleaning and improving the recovery rate of flux after cleaning.
High membrane bonding strength and good wear resistance
Silicon carbide membranes have high membrane bonding strength and good wear resistance, which means that the membrane material is not easily damaged during the cleaning process and can maintain a good physical state, which helps to improve the recovery rate of flux after cleaning.
Efficient cleaning strategies
New cleaning strategies developed in the study, such as the one-step chemical cleaning method of alkali-activated persulfate oxidation ceramic membranes, have been proven to effectively remove irreversible membrane fouling, shorten the cleaning time, and achieve similar cleaning effects, thereby achieving high-flux recovery.
Studies have shown that the use of appropriate cleaning methods, such as chemical cleaning under specific conditions, can restore membrane flux to nearly 100%. For example, after cleaning with sodium hypochlorite and hydrochloric acid, the membrane flux can be restored to about 600-800L/(m2·h), with a recovery rate of 90-107%.
Water treatment is an indispensable part of modern society, and its importance is reflected in many aspects, including but not limited to the following aspects:
Ensure the safety of drinking water:
Water treatment can remove impurities, harmful substances and microorganisms in water to ensure the safety and hygiene of drinking water. Through effective water treatment technology, water pollution can be prevented, human health can be protected, and diseases caused by drinking unclean water can be avoided.
Maintain the ecological environment:
Wastewater treatment is an important means to prevent water pollution. By treating industrial wastewater and domestic sewage, the pollution of rivers, lakes and oceans by harmful substances can be reduced, and the health of aquatic organisms and ecosystems can be protected. After sewage treatment, it can also be used for agricultural irrigation, urban greening, etc., to achieve the reuse of water resources and reduce the pressure on natural water bodies.
Promote industrial development:
In industrial production, the quality of water directly affects the quality and production efficiency of products. Water treatment can ensure that industrial water meets production requirements and improve product quality and production efficiency. Effective water treatment can also extend the service life of equipment and reduce equipment failures and downtime caused by water quality problems.
Ensure public safety:
In natural disasters (such as floods, earthquakes) or emergencies (such as chemical leaks), water treatment can quickly purify contaminated water sources and provide safe drinking water and clean water for rescue and reconstruction work. By establishing an emergency water treatment system, the health and safety of the public in emergency situations can be guaranteed.
Promote water resource management:
Water treatment is an important part of water resource management. Through scientific water treatment technology and management methods, the rational allocation and efficient use of water resources can be achieved. Water treatment can also promote the recycling and reuse of water resources and reduce the waste and pollution of water resources.
Improve the quality of life of the public:
Clean and safe water resources are one of the key factors in improving the quality of life of the public. Water treatment can ensure that residents use clean and hygienic water resources in their daily lives, thereby improving the quality of life and happiness.
