SINOKLE Ultra-fine SiC Membrane Filter for Industrial Wastewater Reuse
In demanding industrial water-treatment scenarios such as petroleum, petrochemicals, power, steel, dyeing/printing, and papermaking, conventional membrane modules often face bottlenecks of easy fouling, low flux, poor temperature and corrosion resistance, short service life, and high O&M costs, making it difficult to meet the needs of fine filtration of oily wastewater and high-standard reuse.
SINOKLE (Shenzhen) Technology Co., Ltd., together with internationally renowned membrane enterprises, has launched the ultra-fine SiC membrane filter, adopting a new-generation silicon carbide (SiC) inorganic ceramic membrane technology. With cross-flow filtration, high flux, anti-fouling, and long service life as its core advantages, it provides a stable and reliable membrane-separation solution for the deep treatment and reuse of industrial wastewater.
I. Technical Core: SiC Inorganic Ceramic Membrane + Cross-flow Filtration for Robust Separation Performance
The SINOKLE ultra-fine SiC membrane filter uses a silicon carbide inorganic ceramic membrane as the core separation medium, combined with a cross-flow filtration mode, forming a highly efficient and stable separation system:
Cross-flow filtration: stable operation under high suspended-solids conditions, not prone to concentration polarization and membrane fouling, with low operating pressure and easy cleaning and maintenance.
Excellent hydrophilicity: uses inorganic carbon material SiC with industry-leading hydrophilicity, and filtration flux far exceeding traditional membrane products.
Honeycomb structure: honeycomb design of the membrane core gives high mechanical strength, large packing density, and good sealing, enabling convenient installation and maintenance.
Stable separation: uniform and stable pore size with median particle size ≤1.0 µm, achieving ultra-fine removal of oil and suspended solids.
Entirely physical separation: no chemical addition and no secondary pollution, suited to complex industrial water with high temperature, strong corrosion, and high oil content.
II. Eight Core Technical Advantages
Ultra-fine separation
Uniform and stable separation pore size with median particle size ≤1.0 µm delivers excellent oil and suspended-solids removal, and effluent meeting ultra-low-permeability reinjection and high-standard reuse requirements.
Extra-long service life
SiC material is corrosion-resistant and anti-aging; under normal operating conditions the service life can reach over 5 years, far exceeding organic membranes and conventional ceramic membranes.
Superior chemical stability
Resistant to strong acids and bases and tolerant of various organic solvents, with strong physical rigidity and high hardness, adapting to complex and harsh water quality.
Excellent thermal stability
Can withstand high temperatures up to 800°C, suited to direct treatment of high-temperature wastewater, eliminating the cooling step for energy-saving, high-efficiency operation.
Extremely high filtration flux
Water flux is over 100× that of organic membranes and 2–4× that of conventional ceramic membranes, greatly improving treatment efficiency.
Low-pressure, low-consumption operation
Low operating pressure and small energy consumption, simple pre-treatment and small footprint, with significant comprehensive operating-cost advantages.
Easy cleaning and maintenance
Convenient cleaning with strong performance recovery after rinsing; simple membrane-element maintenance reduces whole-life-cycle O&M costs.
Honeycomb high-strength structure
The honeycomb membrane core offers high mechanical strength, high packing density, and good sealing, enabling efficient and convenient installation and maintenance.
