Industrial and Municipal Silicon Carbide Membrane Applications
The application breadth of the Silicon Carbide Membrane family spans municipal treatment upgrades, industrial wastewater reclamation, chemical processing, and high-load filtration environments that demand stable flux and wide chemical tolerance.
These silicon carbide membranes operate reliably under fluctuating water quality, high suspended solids, strong oxidants, and severe pH cycling.
Municipal Water & Wastewater Treatment (MBR, RO Pretreatment, Tertiary Polishing)
This category uses silicon carbide membranes to maintain stable filtration under variable municipal influent and regulatory-driven effluent limits.
- In MBR upgrades, flux remains stable within 150–300 LMH, even under peak COD loads exceeding 800 mg/L.
- During RO pretreatment, TMP remains below 0.6–1.0 bar, reducing chemical cleaning frequency by more than 40% compared with polymeric membranes.
- Tertiary polishing achieves particle removal below 0.1 µm, enabling consistent discharge compliance for plants treating 10,000–50,000 m³/day.
Industrial Wastewater & High-Strength Organic Effluent
These environments deploy silicon carbide ceramic membranes for continuous filtration under high organic load, oils, solvents, and variable pH conditions.
- SiC achieves 95% flux recovery after CIP, even when influent TSS exceeds 1500 mg/L in chemical production facilities.
- Stable filtration at pH 1–13 supports effluent from plating, electronics, and fine-chemical processes without membrane degradation.
- Systems running at 200–400 LMH reduce OPEX by up to 35%, due to lower cleaning frequency and longer membrane life.
Mining, Metallurgy, Slurry Processing & Solid–Liquid Separation
In high-abrasion and particle-rich environments, silicon carbide filtration membranes maintain superior mechanical stability and wear resistance.
- Tubular SiC membranes tolerate TMP up to 3 bar, enabling treatment of tailings water with >3000 mg/L suspended solids.
- Flux above 180–250 LMH is sustained, even during continuous slurry recirculation at flow velocities >3 m/s.
- SiC modules remain chemically stable in alkaline flotation streams, supporting pH levels frequently reaching 11–12.
Chemical, Petrochemical, and Process-Liquid Clarification
These processes rely on silicon carbide membrane filters to separate catalysts, recover valuable compounds, and protect downstream equipment.

FAQs for Silicon Carbide Membrane
A Silicon Carbide Membrane provides intrinsic hydrophilicity and a 0.3° contact angle, which reduces irreversible fouling even when COD exceeds 800 mg/L. Its open porosity (40–45%) supports high turbulence inside channels, preventing solid deposition. The rigid SiC structure also withstands higher scouring velocities, allowing stable flux in high-load conditions.
The recrystallized SiC matrix remains chemically inert across pH 1–13 during continuous operation. It also tolerates oxidants such as chlorine, ozone, and hypochlorite without degradation. These properties make the membrane suitable for chemical, petrochemical, and surface-treatment wastewater where polymeric membranes typically fail.
A Silicon Carbide Membrane withstands stronger backwash pressure, air-scouring force, and oxidizing agents, enabling deep pore cleaning. After harsh CIP cycles, flux recovery often exceeds 90–95%. The mechanically rigid pore structure prevents deformation, ensuring long-term recovery consistency.
SiC membranes can be customized in length, outer diameter, and interface geometry to match existing housings. This minimizes structural modifications for EPC contractors. Their stable TMP tolerance supports plug-and-play upgrades for MBR, RO pretreatment, and industrial wastewater retrofits.
The membrane remains stable in salinity levels above 35,000 ppm and resists scaling under fluctuating ionic loads. Its hydrophilicity reduces biofouling and particulate deposition common in seawater. These characteristics make it ideal for desalination pretreatment and offshore process-water filtration.
Yes, SiC's negative surface charge and microstructure reduce oil adhesion compared with polymeric membranes. This results in more stable flux under emulsified oil conditions. It also allows aggressive chemical cleaning to remove stubborn oil-based foulants.
Multi-channel SiC tubes increase hydraulic efficiency and reduce pressure drop. Smaller hydraulic diameters enhance shear forces, lowering the fouling rate. These design features help maintain LMH stability in high-viscosity and particle-rich feed streams.
A Silicon Carbide Membrane has high thermal conductivity, enabling rapid heat dissipation. This reduces stress concentration during temperature spikes. As a result, the membrane tolerates rapid temperature changes that would typically crack alumina-based membranes.
