What are Water Filters?
Water filters remove pollutants including sediment, taste and hardness, odour, and germs from water, resulting in higher-quality water. We provide a large choice of filters and cartridges to handle any number of water-related difficulties, from creating better-tasting drinking water to more specialized applications such as brewing coffee and making crystal clear ice.
Types of Filters
There are five type?s of water filters depending on your application:
1: Mechanical filters
2: Absorption filters
4: Ion exchange
5: Reverse osmosis
Each one of the above mentioned processes address a different water problem and many filters actually use a combination of these methods to perform multiple levels of filtration.
How do water filters work?
Water is one of the most significant chemicals in the world, covering 71 percent of the Earth's surface and containing up to 75 percent of it in the human body.
Agriculture, medicine, science, heating, transportation, food processing and recreation, as well as washing and, perhaps most importantly, drinking, all require large amounts of water.
Drinking water for the majority of us comes from a treated municipal supply that is safe to drink but may have unpleasant tastes and odors from chemicals like chlorine used to disinfect the water and thus keep it free of germs and bacteria. You may also notice that your mains water generates limescale deposits, depending on where you reside.
These difficulties, as well as chlorine taste and odour and lime-scale build-up, are only two of many typical water issues that can be resolved with water filtration. But how do water filters operate in practice?
Mechanical filtration's core concept is to use a barrier to physically remove sediment, debris, or any other particles from water. Mechanical filters can range from simple mesh that filters out big trash to a ceramic filter with an incredibly sophisticated pore structure that allows harmful organisms to be filtered ultra-finely.
Mechanical filtration filters are usually given a micron rating, indicating how successful they are at removing particles of a certain size. You might see the following ratings:
-5 micron –They will remove most particles visible to the naked eye.
-1 micron – They will remove particles which are too small to see without a microscope.
-0.5 micron –They will remove cysts (giardia and cryptosporidium).
Carbon, that is particularly effective at absorbing water-borne pollutants, is most typically used in water filters for absorption. Carbon has a large internal surface that is packed with nooks and crannies that may trap chemical impurities like chlorine, which is why it absorbs toxins so readily.
Granular activated carbon (GAC) is found in most household filters, and it absorbs undesirable tastes and odours. Carbon block elements are used in more expensive filters, which are generally more effective and have a micron rating for particle removal.
Wood and coconut shell are two common materials used to create carbon for filters, with coconut shell filters being more effective but also more expensive.
The action of chemically isolating a material is known as sequestration. Scale-inhibiting filters often use food-grade polyphosphate to trap the calcium and magnesium minerals that produce lime-scale and corrosion. Polyphosphate, on the other hand, is usually only used in trace levels, and it just inhibits scaling rather than eradicating it. This implies that rather than softening the water, polyphosphate acts to keep the minerals in the solution, preventing them from forming scale on any surfaces they come into touch with.
4: Ion Exchange
Ion exchange softens hard water by exchanging magnesium and calcium ions with other ions like sodium or hydrogen ions. Ion exchange, unlike scale inhibition, physically eliminates hard minerals, lowering lime-scale and making water appropriate for applications where it is kept at a continuous high temperature, such as in commercial coffee machines.
5: Reverse Osmosis
The method of eliminating dissolved inorganic particles (such as magnesium and calcium ions) from water by forcing it through a semi-permeable membrane under pressure so that the water flows through but most of the pollutants are left behind is known as reverse osmosis (RO).
In order to return water with minimal pollutants, reverse osmosis is frequently paired with a variety of different filters such as a mechanical (sediment) filter and an absorption (activated carbon) filter.
