Based on known technology from Diesel Particulate Filters, a range of silicon carbide filter carriers for liquid filtration have been developed to address the challenges of harsh operation environments unsuitable for conventional polymeric membrane products. A variety of different membranes can be applied to the carrier, depending on the final application.
Oxide based ceramic liquid filters, already used in such applications are being replaced with liquid filters based on our silicon carbide carriers, typically for micro filtration and ultra filtration applications providing superior performance in a range of industrial applications.
The benefit of silicon carbide filters based on our carriers compared to oxide based liquid filters, is the extended operating and cleaning range (0-14 pH), and improved thermal shock resistance. These features enable treatment of aggressive alkaline fluids and cleaning operations with aggressive alkaline cleaners or rapid and aggressive thermal cleaning.
Typical applications are applications for de-oiling and silica removal from oilfield produced water as well as many other industrial applications such as industrial wastewater, chemical production, and many others.
