FR-E720S-0.4K-CHT MITSUBISHI Filter Modules

Product  Description：

The Mitsubishi Sterapore filter module is a high-efficiency filtration system utilizing Polyvinylidene Fluoride (PVDF) or Polyethylene (PE) hollow fiber membranes. These modules are primarily designed for Membrane Bioreactors (MBR) and advanced water purification. Unlike conventional sand filters, these modules use a physical barrier with microscopic pores to remove suspended solids, bacteria, and viruses from liquids.

Technical Parameters

While specific parameters vary by model (e.g., the 5000 series or the newer SUR series), the general technical specifications include:

• Membrane Material: Polyvinylidene Fluoride (PVDF) or Polyethylene (PE).

• Pore Size: Typically ranges from 0.05 to 0.4 micrometers (Microfiltration to Ultrafiltration).

• Fiber Diameter: Generally an outer diameter of 2.0 mm to 2.8 mm.

• Operating Temperature: 5 to 40 degrees Celsius.

• pH Tolerance: 1 to 12 (allowing for intensive chemical cleaning).

• Operating Pressure: Typically vacuum-driven (suction) at -10 to -50 kPa.

• Flux Rate: Varies by water quality, usually 0.4 to 0.8 cubic meters per square meter per day.

Product Advantages

The Mitsubishi design offers several distinct benefits for industrial and municipal users:

• High Packing Density: The hollow fiber design provides a massive surface area within a compact footprint, allowing for smaller treatment plant designs.

• Durability and Longevity: The PVDF material is highly resistant to chemicals (like chlorine) and mechanical stress, reducing the frequency of fiber breakage.

• High Permeate Quality: The consistent pore size ensures the removal of nearly all suspended solids and pathogens, often meeting strict reclaimed water standards.

• Low Energy Consumption: These modules are designed to operate at low suction pressures, which minimizes the electricity required for the filtration process.

• Easy Maintenance: The "outside-in" flow direction allows for effective air scouring, which shakes off accumulated sludge from the fiber surfaces.

Usage Precautions and Maintenance

To ensure the longevity of the modules, users must adhere to specific operational guidelines:

• Pre-treatment: Large debris, hair, and abrasive particles must be removed via fine screening (typically 1mm or less) before reaching the membranes to prevent physical damage.

• Chemical Cleaning: Regular Maintenance Cleaning (MC) and periodic Recovery Cleaning (RC) using sodium hypochlorite or citric acid are necessary to remove organic and inorganic scaling.

• Avoid Dryness: Once the membranes are wetted, they must remain wet. Drying out the fibers can lead to irreversible loss of permeability.

• Pressure Monitoring: Transmembrane Pressure (TMP) must be monitored constantly; a sudden rise usually indicates fouling or a need for immediate cleaning.

Product Applications

Mitsubishi filter modules are versatile and used across various sectors:

• Municipal Wastewater Treatment: Upgrading existing sewage plants to meet higher discharge standards or for water recycling.

• Industrial Wastewater: Treating high-strength waste from food and beverage, textile, and pharmaceutical industries.

• Landfill Leachate: Handling the complex and highly contaminated runoff from waste sites.

• Drinking Water Purification: Removing turbidity and microbiological contaminants from surface water or groundwater.

• Pre-treatment for Reverse Osmosis (RO): Protecting RO membranes from fouling in desalination and ultrapure water production.
