Filtration of water and liquid

When it comes to filtering water and liquid, there are countless products and options, depending on which filtration problem you want to find a solution for. The problems can be many - there can be too much ocher in the water or you have to filter liquid within the brewing or pharmaceutical industry, where we have filters with an efficiency of up to 99.9999%.

Ocher in the water – What is it?

Ocher is a naturally occurring soil type that will appear in the form of a yellow, red or brownish color. Ocher is not toxic to humans, but at the same time ocher is not the most inviting thing to have in your water, precisely because of the color it gives. At the same time, the water can have a strong smell, which is due to its lower PH value. Although ocher is not dangerous for humans, it is a different matter for some animal species. Among other things. then fish are not particularly happy with ocher in the water.

The solution to remove ocher from the water

Filter-Online receives a great many inquiries about ocher/iron in the water from customers throughout Scandinavia. We could quickly see that it was a widespread problem, especially for people with their own wells. We therefore put together a set that could be used to reduce e.g. ocher in the water, but also other unnecessary things such as organic matter, pesticides and heavy metals. On selected sets, an active carbon filter is included, which absorbs any bad smell in the water.

The kits are available in both standard and jumbo sizes with different types of filter compositions. The larger the filter housing – the greater the flow. This means that you can adapt the solution to your specific needs.

The filter housings are available in both plastic and stainless steel.

Ocher kit in stainless steel

All filter housings and elements are food approved in Denmark and the rest of the EU.

3M Aqua-Pure filtration products

Filter-Online are dealers of products from 3M – a company known throughout most of the world. We have a selection of their Aqua-Pure range which includes filters for various filtration purposes. Many of our regular customers faithfully choose 3M's products and this makes us proud dealers of exactly Aqua-Pure from 3M.

Filtration of liquid – Filter housings and filter bags

At Filter-Online, we also work with products for liquid filtration. We have, among other things, bag filter housings – both in plastic and stainless steel in several different sizes, so that they suit different sizes of production. A bag filter housing is often used in connection with pre-filtration, where the coarse is caught. At the same time, the bag filter housings can handle a high flow, which only makes it more optimal as the first filter in the process.

In addition to the filter housings, Filter-Online has a large selection of filter bags made of polypropylene (PP). They are available in 4 different sizes to suit the houses and with filtration levels from 0.5 µm all the way up to 200 µm.
