Product Description

Silicon Carbide (SiC) represents the pinnacle of ceramic membrane technology. Engineered for high performance in the most demanding conditions, Semicorex Silicon Carbide Membranes leverage the unique material properties of silicon carbide to provide unparalleled filtration efficiency, durability, and throughput.

1. Advanced Filtration Mechanism

Semicorex Silicon Carbide Membranes operate on a pressure-driven separation process. As wastewater flows across the membrane surface, the pressure differential forces pure water through a precise 0.1-micron pore structure.

Selective Permeability: Due to the inherently hydrophilic and oleophobic (water-attracting and oil-repelling) nature of Silicon Carbide, organic substances like oil are effectively blocked at the surface.

Contaminant Isolation: Solids, pathogens, and various pollutants are retained on the membrane exterior, forming a concentrated layer.

Self-Cleaning Capability: To ensure long-term operational stability and prevent performance degradation, the system utilizes periodic backwashing. Reversing the water flow flushes the accumulated solids off the membrane surface, restoring flux and extending the lifespan of the filter.

2. Superior Material Performance

The natural characteristics of Silicon Carbide provide a significant competitive advantage over traditional polymer or alumina membranes.

Exceptional Hydrophilicity: With an ultra-low water contact angle of just 0.3°, the membrane surface is naturally "thirsty" for water. This results in an industry-leading pure water flux of up to 3200 LMH (Liters per Square Meter per Hour).

Oil-Water Separation: The membrane naturally repels oily substances, making it the ideal solution for complex industrial emulsions.

High Precision: While the standard pore size is 0.1 μm, our technology can achieve a maximum filtration precision of 20 nm, reaching into the ultrafiltration spectrum to remove even the finest sub-micron particles.

3. Versatile Application Cases

Our Silicon Carbide Membranes are deployed globally across diverse sectors, proving their resilience and efficiency:

Drinking Water Purification: Providing safe, pathogen-free potable water.

Seawater Desalination: Effective pre-treatment for RO systems to reduce fouling.

Oil-Water Separation: Recovering oil or cleaning wastewater in petrochemical and manufacturing sectors.

Seafood Processing: Successfully managing large-scale wastewater treatment with capacities reaching 3000 m³/d.

Marine & Shipping: Specialized treatment of desulfurization wastewater from vessels, ensuring full compliance with stringent MEPC.340(77) international environmental regulations.
