The application of silicon carbide (SiC) membranes in municipal wastewater applications has been growing rapidly over the past couple of years. With numerous key performance and operational advantages, SiC membranes have demonstrated competitive life cycle cost evaluations with polymeric membranes despite having higher capital costs. SiC has been successfully applied in membrane bioreactor (MBR) and sludge thickening applications. Ongoing development of SiC membranes in other applications such as tertiary filtration, sanitary sewer overflow (SSO), and combined sewer overflow (CSO) will further expand the reach of SiC membranes in wastewater. Every wastewater application has its own set of unique challenges that test the reliability of membrane systems. While challenges may be varied and numerous, they always compromise two key factors: hydraulic capacity and/or membrane integrity. SiC’s unique set of material properties directly address common fouling and membrane integrity issues in membrane wastewater systems. Common challenges in membrane systems include aggressive irreversible fouling, poor recovery after CIP, material and performance degradation due to chemicals, TMP limitations, extended non-operational periods, extreme weather, damage due to debris, and variable influent quality. This presentation will present data and case studies using SiC system in MBRs, sludge thickening, tertiary filtration, and storm flow treatment. Data presented will include both commissioned operating plants as well as pilot studies.
