Tiếng ViệtCERAMIC FLAT SHEET MEMBRANE TECHNOLOGY – EUROPEAN QUALITY
Ultra filtration technologies with a pore size of 0.1 µm are commonly understood as filtration solution to remove suspended solids such as clay and silt, pollen, algae, precipitated metal oxides as well as fractions of colloids. They are also a physical barrier for germs and bacteria.
SHC MEMBRANE uses the most advanced water purification technology in the world, applying a Silic Carbide flat membrane filter – which can filter various contaminated water sources.
MORE THAN A COMMON ULTRA FILTRATION
The SiC flat ceramic membrane is a dense sintered body, so it has the ability to filter to 0.1 micrometer, which means it can filter viruses, such as Corona virus (with a size of 0.125 micrometer).
SiC is one of the few membrane materials that are naturally and permanently hydrophilic, meaning that organic foulants, including oils, are repelled by the membrane while water is naturally drawn in.
The SiC ceramic flat membrane achieves unprecedented filtered water quality, and consequently being the best pre-filtration solution for all NF and RO applications. The RO membrane is very susceptible to damage due to scaling, because the pre-filtration steps are not clean, not guaranteeing the ideal turbidity for the RO membrane, so it can only be used for 2 – 3 years. However when combined with the ceramic membrane provided by SHC MEMBRANE, the RO membrane can increase the lifespan to 7 – 10 years.
HOW DOES IT WORK
A slight vacumn, typically around 0.1 – 0.2 bar is applied to the membrane to pull the water through. Solids and other contaminants are blocked by membrane pores and retained on the surface.
Periodically, the water is reversed back through the membranes to dislodge and remove the solids that have accumlated on the surface, following the discharge path.
In some applications, ozone aeration is used between the plates to create a scouring effect that helps to keep the membrane clean. A variety of booster sprays are used to quickly and efficiently remove solids from the membrane surface.
