The Working Principle of Household Water Purifiers

The Working Principle of Household Water Purifiers
Household water purifiers are designed to remove impurities from water, making it safe
and suitable for consumption. But how exactly do they work? Let’s take a closer look at the underlying principles.
Filtration: This is one of the most common methods used in water purifiers. There are different types
of filters, each with a specific function. For example, sediment filters are used to remove large particles such
as sand, rust, and dirt. These filters have pores of a certain size that trap

the larger impurities, allowing only the smaller water molecules to pass through.
Activated Carbon Filtration: Activated carbon is widely used in water purifiers. It has a highly porous structure,
which gives it a large surface area. This property allows it to adsorb a variety of substances, including chlorine,


a semi – permeable membrane is used. When pressure is applied to the water, water molecules are forced through
the membrane, while dissolved salts, heavy metals, bacteria, and viruses are left behind. The pore size of the
reverse osmosis membrane is extremely small, typically around 0.0001 – 0.001 microns.
This is much smaller than the size of most bacteria and viruses, ensuring that the water that passes through is highly purified.
Ion Exchange: Some water purifiers use ion exchange resins to remove certain ions from the water.

In many household water purifiers, a combination of these methods is used to provide multi – stage purification.
Each stage targets different types of impurities, resulting in water that is free from a wide range of contaminants and safe for drinking and other household uses.
