Water filter for home in Kolkata

2nd Sep admin

A water filter reduces water pollution by using a thin physical barrier, a chemical reaction, or a biological response to remove contaminants. For many uses, including agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools, filters purify water to varying degrees. Media filters, screen filters, disc filters, quicksand filters, cloth filters, and biological filters like algae scrubbers are a few examples of several types of water filters.

Water filters for home water production throughout the 19th and 20th centuries were often separated into slow and quicksand filters (also called mechanical and American filters). Paisley, Scotland, is often regarded as the first city to get filtered water for a whole town, even though several small-scale water filtration systems were in place before 1800. The Paisley filter, a forerunner of the slow sand filter, started operating in 1804. Hundreds of slow sand filters were built throughout the 1800s in the UK and Europe. In Lawrence, Massachusetts, an intermittent slow sand filter was constructed and put into operation in 1893 due to ongoing typhoid outbreaks brought on by sewage pollution of the water supply.


Point-of-use filters

Granular-activated carbon (GAC) filters, depth filters, metallic alloy filters, microporous ceramic filters, carbon block resin (CBR), microfiltration, and ultrafiltration membranes are point-of-use filters for domestic usage. Some filters employ several filtration techniques. A multi-barrier system is one illustration of this. To filter tiny amounts of drinking water, utilize jug filters. Some kettles contain built-in filters, primarily to lessen the buildup of limescale.

The plumbing is upgraded with standard Flowmatic cartridge style filters, cylindrical cylinders 250 millimeters (10 in) long by 100 millimeters (4 in) in diameter. They are produced by several companies and come in micron sizes ranging from 0.5 to 100 and activated carbon. Arsenic, bacteria, chlorides, fluoride, nitrates, perchlorates, medicines, salt, and viruses are some major contaminants that filtering frequently leaves behind.


Portable water filters

Hikers, aid agencies during humanitarian crises and the military utilize water filters. These filters are typically compact, transportable, and light (1-2 pounds/0.5-1.0 kg or less) and filter water using a mechanical hand pump. In contrast, some employ a siphon drip mechanism to force water through, and others are integrated into water bottles. A flexible silicon tube with a screen filter is used to pump dirty water through a specific filter and into a container. These filters eliminate the bacteria, protozoa, and microbial cysts that can lead to sickness. Fine mesh filters may need to be cleaned or changed, while ceramic water filters that have been clogged with pollutants need to have their exteriors abraded.


There is no disputing that the available water sources are severely strained due to the increasing water scarcity. Having a water filter at home is essential due to the ease with which most water sources may get polluted. When it comes to water filtration, Propello water purifiers perform incredibly well. The multi-stage filtering technology of a Propello cleaner keeps the necessary minerals in the water while also removing contaminants.
