THE PHYSICS OF SILICON CARBIDE (SIC) FLAT SHEET MEMBRANES
NEXT-GENERATION BACKWASH WATER RECOVERY

The Key Material of the AI Era: Silicon Carbide (SiC)
As a vital third-generation semiconductor material for AI and HPC, Silicon Carbide (SiC) offers exceptional mechanical strength, chemical resistance, and thermal stability, ensuring enduring performance under extreme conditions.
Apuretec integrates advanced SiC materials into industrial water treatment. Unlike traditional polymers, our SiC ceramic membranes easily withstand high-pressure shear forces and heavy impurities, ensuring absolute filtration precision and operational stability in the harshest environments.
Unlike traditional disposable filters, SiC ceramic membranes endure rigorous chemical cleaning and physical backwashing. This maximizes performance and minimizes unplanned downtime, delivering a highly reliable, long-term solution for industrial water management.

Core Technology
-
Extreme Environment Tolerance
Suitable for pH 0-14 and high temperatures. Its superior mechanical strength withstands high-pressure shear forces and heavy suspended solids, maintaining structural integrity with zero risk of chemical degradation.
-
Modular Design & Layout Flexibility
Modular design delivers exceptional system scalability. For space-constrained sites, modules can be vertically stacked into high-density filtration towers. Engineers can flexibly configure high-tower or low-profile matrix arrays based on existing spatial conditions, maximizing footprint efficiency.
-
High Flux with Low TMP
SiC's excellent hydrophilicity and asymmetric pore structure significantly reduce flow resistance. This enables the membrane to maintain sustained high flux and precise separation performance, even under extremely low transmembrane pressure (TMP).

Fields of Application
-
Backgrinding (BG) Wastewater
Apuretec's SiC flat sheet ceramic membranes deliver exceptional wear resistance against high-hardness abrasive suspended solids. Acting as an advanced pre-treatment barrier for UPW and wastewater recovery systems, they effectively intercept impurities, significantly extending the lifespan of downstream RO membranes and ensuring continuous facility operations.
-
Printed Circuit Board (PCB) Process Wastewater
When handling metallic micro-particles and debris, SiC's extreme hardness provides superior resistance to physical wear and particle impact. In heavy metal solids interception and concentration, it withstands continuous high-pressure scouring without risk of piercing or damage. This stable solid-liquid separation ensures consistent water quality while facilitating efficient downstream metal resource recovery.
-
Groundwater Treatment for High Turbidity
Overcoming the clogging and short lifespan limits of sand filters and polymer membranes, SiC's hydrophilicity enables stable high flux at extremely low TMP. It effectively removes suspended solids, colloids, and iron/manganese oxides, providing consistent water quality and low-cost, reliable water sources for remote treatment plants.
Advanced RO pre-treatment for desalination, and MBR systems for industrial zones, science parks, and water recovery centers.
