Product Specifications

Technical details and manufacturing context for Marine Ballast Water Treatment System Filter Cartridge

Definition

This cylindrical filtration cartridge is a replaceable component designed for marine ballast water treatment systems. Its primary function is to physically remove suspended solids, microorganisms, and particulate matter from ballast water during the treatment process. As the primary mechanical filtration stage, it supports compliance with the IMO Ballast Water Management Convention requirements. The cartridge is engineered for high-flow marine applications, with a nominal filtration rating of 25–50 microns (ISO 16889) and a flow rate capacity of 50–200 m³/h. It operates at a maximum working pressure of 1.0–1.6 bar and allows a maximum differential pressure of 0.02–0.15 bar. The operating temperature range is -20 to 60 °C. The cartridge is available in lengths of 500–1000 mm, outer diameters of 60–150 mm, and inner diameters of 25–50 mm, with a weight of 2–8 kg. Materials on file include polypropylene pleated media, stainless steel end caps, and EPDM seals. The filter media material may be PP, PTFE, or SS316L; end cap material may be PP, SS304, or SS316L; and seal material may be NBR, EPDM, or Viton, depending on the specific model. The recommended replacement interval is 8000–12000 hours. All values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. Regular replacement ensures consistent treatment performance and prevents biological contamination transfer between marine ecosystems.

Working Principle

Water flows through the porous filter media, which traps suspended particles, microorganisms, and particulate matter while allowing treated water to pass through to subsequent treatment stages. The pleated polypropylene media provides a large surface area to maximize dirt-holding capacity while maintaining a low pressure drop. As particles accumulate, the differential pressure across the cartridge increases. When the maximum allowable differential pressure is reached, the cartridge must be replaced to maintain flow and filtration efficiency. The cartridge is designed to fit into a housing with specific dimensions, and the seals ensure a leak-tight fit to prevent bypass of unfiltered water.

Frequently Asked Questions

What is the filtration rating of this cartridge?

The nominal particle size retention is 25–50 microns, tested according to ISO 16889. This is a reference range; the actual rating for a specific model must be confirmed with the manufacturer.

What is the recommended replacement interval?

The recommended service life is 8000–12000 hours, depending on operating conditions and water quality. Regular monitoring of differential pressure is advised to determine the optimal replacement time.

What materials are used in this cartridge?

Materials on file include polypropylene pleated media, stainless steel end caps, and EPDM seals. However, the filter media, end cap, and seal materials may vary (e.g., PP, PTFE, SS316L, NBR, Viton) depending on the model. Verify material compatibility with seawater and your specific application.

How do I know if the cartridge is compatible with my system?

Check the cartridge dimensions (length, outer diameter, inner diameter) and the housing seal compatibility. The cartridge length is 500–1000 mm, outer diameter 60–150 mm, and inner diameter 25–50 mm. Always verify these values with the system manufacturer or supplier.
