Advantages of LiqTech's revolutionary silicon carbide ceramic membranes

For more than two decades, LiqTech has manufactured products of re-crystalized silicon carbide that provides state-of-the-art silicon carbide ceramic membrane products for gas and liquid purification. We specialize in two business areas: silicon carbide ceramic membranes for liquid filtration and diesel particulate filters (DPFs) for the control of soot exhaust particles from diesel engines. Using nanotechnology, we develop proprietary products using patented silicon carbide technology. Our products are based on unique silicon carbide ceramic membranes that facilitate new applications and improve existing technologies. 

Our diesel exhaust and liquid filtration products utilize silicon carbide ceramic membranes, which have certain qualities that we believe make our products more effective than our competitors. Unlike filtration products that use aluminum oxide, silicon carbide membranes are chemically inert and temperature resistant. Furthermore, silicon carbide ceramic membranes exhibit a high degree of hydrophilicity (a tendency of a surface to become wet or to absorb water) that results in unique flux (low energy consumption). Silicon carbide is also very durable with a hardness second only to diamond, making it a highly desirable material for a variety of aggressive fluids in industrial applications. As a result, we believe that such superior physical properties make our products desirable in both exhaust emissions control products and liquid filtration products.
