Ballast water filter element – Mainly used in ballast water system.

Ballast water filter is one of our marine filter elements, with the implementation of the BWM Convention, more and more customers ask us for information about the product.

Today, I’m here to give users a detailed introduction to this product, as well as the precautions before we buy it.

What is the ballast water system?

– The composition of the ballast water system

Ballast pump

Ballast water pipe road

Ballast tanks and related valves

– Effect

In the operation of ships, draught, stability, roll, and pitch need to be adjusted according to specific conditions. This task can be accomplished by means of the ballast system. By changing the quantity of water in each ballast tank.

– Impact of no installation of ballast water system

It has great harm to the environment.

There are a lot of viruses, fish and plankton in ballast water. If ballast water arrives in another country and these small creatures do not have natural enemies, the ecological balance will be greatly damaged.

The role of ballast water filter element in the ballast water system

Ballast water system has many processes to deal with ballast water. Larger organisms and impurities need to be disposed of first by ballast water metal filters.

Technical parameters of the ballast water filter element

– Material

Unlike other marine filter elements, the ballast water filter has a very high demand for materials.

In general, 304 material is not considered. Commonly used materials are SS316L and Duplex steel 2205, 2507, 32750.

If you only consider the price, buy the 304 stainless steel filter element products, in the process of using, you will regret the decision.

– Conventional size

100*1000mm

The size is not fixed. We can customize products with different specifications according to customers’ needs.



– Normal working temperature

-30 – 300

There is no need to think too much about this, and there is no place where the seawater will exceed this range.



– Filter precision

2~200 Micron

All organisms above 2 microns can be filtered.

– Product composition

1.       Support layer. Perforated metal tube or wedge wire screen tube, I suggest using wedge net as the support layer.

2.       Filter layer. Stainless steel wire mesh, the most important part. It should be noted that when you do sample quality testing, you need to focus on testing the quality of the metal mesh of the filter layer and whether the parameters are qualified.

3.       Interface. Thread

These are the main components of it.

When the BWM Convention was formally implemented, I was excited.

In addition to environmental protection, the sales of filter elements will definitely increase dramatically, Ha ha ha ha.
