- BB: Big Blue (4.5" outer diameter)

 IV. Core Features

1. Seawater Dedicated: All PP material + EPDM sealing, salt-resistant, antimicrobial, corrosion-resistant, suitable for seawater desalination/high-salinity conditions.

2. High dirt-holding capacity + low pressure drop: Large pleated structure area, strong dirt-holding capacity and long service life, protecting downstream RO membranes.

3. High flow rate: 20-inch large diameter, sufficient flow rate and low pressure drop, suitable for marine/land-based seawater systems.

4. Economical and versatile: Compatible with Pentek ECP5-20BB, SPC-45-2005, etc., low cost and easy to procure.

 V. Typical Applications

- Seawater desalination: RO reverse osmosis pre-filter, intercepting sediment, shells, and colloids to protect the reverse osmosis membrane.

- Marine systems: Marine seawater filters, cooling water pretreatment.

- High-salinity wastewater: Chemical/power plant high-salinity wastewater pretreatment, ion exchange pre-filtration.
