Water Filter

A water filter is a home appliance that removes unwanted particles in water and purifies it. This is basically done with the help of a fine physical barrier. This filtration process can be a biological process or a chemical process. Any water filter cleans the water to different extents for swimming pools, aquariums, drinking water, and irrigation.

Filtration Methods

There are some processes to filter water such as:

• Ion exchange,
• Adsorption, and
• Sieving.

Contrasting a screen or sieve, a water filter can eliminate micro particles.

Types of Filters

There are three types of water filters; they are

• water treatment plant filters,
• point-of-use filters, and
• portable water filters.

Point-of-use water filters

These filters are designed especially for home usage, and they have granular activated carbon filters (GAC), which are utilized in ultra filtration membranes, carbon block resin (CBR), micro porous ceramic filters, metallic alloy filters, and carbon filtering.

Some filters follow multiple filtration processes instead of just one method and a multi-barrier system is a simple example of the same. Coming to jug filters, they are used for filtering small amounts of drinking water. Some of the kettles use in-built filters to minimize lime scale buildup.

Portable Water Filters

A number of organizations and military forces use water filters. These have to be transported from one place to other place. In such cases, portable water filters come in picture. These are very small, light, and portable.

Each portable water filter weighs up to two pounds and can be transported to effortlessly. They work by a mechanical hand pump to pull the water out. Dirty water is removed through a screen-filtered flexible silicon tube via a specialized filter. This filter filters microbial cysts, protozoa, and bacteria, which are responsible for creating many health diseases.

Water Polishing

Water polishing refers to filtration of water by removing small and unwanted dust particles and purifies water. The procedure and its sense differ from function to function.

Working Principle of Water Filtration

Nowadays, most of the drinking water gets contaminated with increasing pollution. Today, it is not healthy to drink water without purifying it; consequently, water filter has become a necessary kitchen appliance.

Coming to the working of water filter, in any water filter there are certain stages to purify water. Poured water gets filtered in these stages and at last stage purified water comes out. By means of transparent water filters, one can see the internal mechanism.

Water Filter Sizing for the Residential Use

Nowadays, the usage of water filters in homes is increasing like never before. Considering this, manufacturers are developing dedicated water filters for small homes too. They are developing high efficient water filters in small sizes at affordable costs.

Water Filter Sizing for Spas and Commercial Pools

Water filters are specially designed for spas and commercial purposes. These water filters are available in large size and consume very high amounts of electric energy.
