Cembrane’s Silicon Carbide (SiC) membrane modules offer a cost-effective and efficient solution for upgrading traditional sand filtration systems resulting in higher output and improved water quality at a lower cost. The unique properties of SiC, which ironically is derived from sand, enable it to act as a psychical barrier for particles, microorganisms, bacteria, and even emerging contaminants such as PFAS and pesticides. This leads to a reduction in the usage of coagulants, flocculants, and disinfectants, and a significant improvement to the filtered water quality.


A key benefit of using SiC membrane modules is the ability to easily and quickly upgrade existing sand filter basins or settling tanks. The submersible nature of the SiC modules allows for easy installation, utilizing existing basins hence increasing capacity without the need for extensive modifications and civil works. Operation can even be in gravity mode, without the use of pumps to drive filtration, continuing the simple operation of the Sand filters. This leads to a cost-effective and efficient upgrade that can provide a substantial enhancement in capacity, efficiency, and water quality all within the same footprint.

Below table presents an overview of the key differences between Cembrane’s SiC membrane modules and traditional sand filtration

Upsets in feed water quality is well known to cause problems in filtrate capacity and water quality of a Sand filter. However, with SiCBlox’s unique the filtrate quality & capacity will remain the same as shown below from a surface water treatment site.
