Filters for Sea Water Treatment & Reverse Osmosis Systems


Before we begin presenting our sea water filters, we would like to answer some frequently asked questions.

Can you ship to Middle-East? We are shipping Filternox® filters at least once a week to countries in the Middle-East region including:

Qatar, United Arab Emirates, Jordan, Lebanon, Egypt, Iran, Oman, Yemen and Bahrain.

Can it withstand harsh atmospheric conditions like excessive heat, sand storms or moisture? How about high salinity?
Our filters are trusted by many global brands and can keep working flawlessly with certified UV and IP resistances. We can build filters with super-duplex materials for extremely salty sea water and brackish fossil aquifers.
Why do I need to filter sea water? Organic and inorganic TSS, algae, sea species.
Are you able to provide maintenance service? Our filters do not require frequent maintenance, however we are able to provide service personnel worldwide.



The size of dirt particles contained in sea water varies widely. Therefore sea water filtration needs more care than other fluids. A very special filtration solution is required to remove particles from 10 mm at one end of the spectrum down to 50 micron particles at the other. It requires filtration of both coarse and fine particles at the same time.

Filternox® offers special models, KFH, KTW and KQR which have both coarse and fine filtration stages in one body and both featuring an independent automatic self-cleaning system.

Filternox® automatic self cleaning filters are used for sea water filtration on oil platforms, the protection of heat exchangers, ultra filtration and Reverse Osmosis units as well as recreational uses.

Another important consideration in the filtration of sea water is the corrosive effect it has. Filternox® offers the best permanent solution with a rubber coating over its stainless steel body.
