Technical Analysis: Why This Configuration?

Premium Material Selection

Stainless steel 316 serves as the foundational guarantee for this filter. This material offers exceptional corrosion resistance, withstanding exposure to various chemicals and making it particularly suitable for pharmaceutical, food, and chemical industries. Electrolytic polishing not only renders the equipment surface mirror-smooth, reducing material adhesion, but more importantly eliminates potential dirt-trapping areas formed by microscopic irregularities, meeting the highest standards of sanitary design.

Innovative Membrane Stack Design

Each filter incorporates two 16-inch Discwell series stacked membrane stacks, a design that maximizes filtration space utilization. The membrane stacks are constructed from cellulose, resin, and other filtration materials using a unique layered structure. Each disc is sandwiched between two circular cardboard edges and assembled with a support guide plate and a central polypropylene skeleton.

The unique advantage of deep-bed membrane stack filtration lies in its dual filtration mechanism: it not only removes particulates through mechanical interception but also utilizes electrostatic adsorption to capture negatively charged contaminants, significantly enhancing filtration efficiency.

Sealing and Connection System

Fluororubber seals were selected for their exceptional chemical resistance and high-temperature tolerance, ensuring stable sealing performance under demanding conditions. The filter base employs either a flat compression seal or dual O-ring joints to connect with the bottom central outlet channel, guaranteeing zero leakage throughout system operation.

Both liquid inlet and outlet ports are located at the filter base. This design facilitates installation and connection while minimizing dead space, meeting sanitary design requirements.

Advantages of sanitary membrane stack filter housing

This 16-inch sanitary membrane stack filter housing offers distinct performance advantages:

1. High contaminant holding capacity: The membrane stack filter media possesses substantial contaminant holding capacity, up to 4kg per square meter, significantly extending filtration cycles.

2. Backwash-Capable Design: The membrane stack can undergo direct steam sterilization or hot water disinfection and supports backwashing operations, substantially lowering operational costs.

3. Simplified Operation: Compared to traditional plate-and-frame filter presses, this filter eliminates dripping and plate adhesion issues, making replacement faster and more efficient.

4. Wide Adaptability: Offers excellent flexibility for varying production batches, particularly suited for non-continuous manufacturing scenarios.

Application of sanitary membrane stack filter housing

This filter is widely used across multiple industries:

• Beverage Industry: Clarification filtration for wine, beer, syrups, juices, etc.
• Pharmaceutical Industry: Meets GMP standards for sterile filtration of pharmaceutical solutions and purification of biological agents
• Fine Chemicals: Suitable for filtering high-viscosity liquids like silicone oil and lubricants
• Solvent Treatment: Used for filtering and purifying solvents such as coatings and amines
