The Flat Sheet MBR Membrane provides an innovative and effective solution for water filtration. It separates contaminants like suspended solids and microorganisms from effluent, using a micro-porous design that outperforms hollow fiber membranes in terms of fouling resistance and ease of maintenance. This system works by filtering water through a fine barrier, resulting in clean effluent suitable for discharge or reuse.

In-Situ Chemical Cleaning: The SINAP25 membrane is designed for longer cleaning cycles lasting more than 3 months, using chemicals like sodium hypochlorite for organic fouling and oxalic acid for inorganic fouling, reducing maintenance frequency and operating costs.
Easy Inspection and Parts Exchange: The membrane elements allow for quick inspection and part replacement, typically completed in 15 minutes or less, minimizing downtime and maintenance costs.
Durability and High Filtration Efficiency: Made from PVDF (Polyvinylidene Fluoride), the SINAP25 offers exceptional chemical stability, fouling resistance, and mechanical strength, with an asymmetric pore structure for improved filtration performance.
Superior Pollution Resistance: With a 0.1 µm pore size, the SINAP25 blocks fine particles while allowing smaller contaminants to pass through, using its asymmetric structure for better resistance to pollutants and easy removal of larger particles via aeration.
Membrane Structure and Performance: The SINAP25 features an optimized membrane structure, including the membrane panel, spacer, and membrane layers, ensuring high filtration efficiency, handling high concentrations of activated sludge, and minimizing fouling and scaling.
Extended Cleaning Cycles: The SINAP25 membrane's longer cleaning cycles reduce the need for frequent maintenance, helping to lower overall operating costs and enhance system efficiency.
Quick and Cost-Effective Maintenance: With a fast inspection and parts replacement process (typically 15 minutes or less), downtime is minimized, reducing maintenance time and associated costs.
Reliable Performance Over Time: Made from durable PVDF material, the SINAP25 provides exceptional resistance to fouling and chemicals, ensuring reliable filtration performance over the long term.
High Filtration Efficiency: The membrane’s asymmetric pore structure and 0.1 µm pore size contribute to high-quality effluent by efficiently blocking larger contaminants while allowing smaller particles to pass through.
Wide Application Range: The SINAP25 is versatile, suitable for municipal sewage treatment, industrial wastewater treatment, and desalination applications, providing reliable performance under various operational conditions.

Q: How should I store used flat sheet crossflow membranes like SINAP25?
A: Store the SINAP25 membrane in a cool, dry place. If not in use for a long period, keep it submerged in a preservative solution.
Q: Why is the flux value of the SINAP25 membrane different from the published value?
A: Flux can vary based on factors like TMP, CFV, and feedwater quality. A drop in flux may indicate fouling or operational issues.
Q: How do I maintain and clean the SINAP25 membrane?
A: Clean with sodium hypochlorite for organic fouling or oxalic acid for inorganic fouling. In-situ chemical cleaning lasts up to 3 months.
