Silicon Carbide Membranes


TecMemTM is the next generation of liquid microfiltration, made from multi layers of recrystallized silicon carbide. The porous carrier, transition and membrane layers are all made of 99% SiC, been consolidated after sintered at 2200℃.

SiC membranes with various pore sizes have been used to filter different types of produced water. For synthetic produced water and produced water from both conventional and unconventional wells, the SiC membrane was found to be effective in removing suspended solids, bacteria and oil. Compared to current technologies for treating wastewater from oil and gas exploration and production, SiC membranes are expected to achieve a smaller footprint, an overall more compact system and reduced chemical usage. These advantages also make SiC membranes attractive for other water treatment applications such as swimming pools.
