The Working Principle of The Water Purifier: Purification Magic Revealed
Pre-filter: Pre-filter is usually installed in the front of the home water pipeline.
its main role is to filter out large particles of impurities in the water, such as sediment, rust, suspended solids, etc.
The filtering accuracy is generally between 5 – 100 microns. Its filtration precision is generally between 5 – 100 microns.
PP cotton cartridge filtration:
PP cotton cartridge is a common primary filtration element in the water purifier, which uses polypropylene fiber material made of meltblown cartridge.
Filtration precision is generally in the 1 – 5 micron.
PP cotton cartridge has a low cost, good filtration effect, easy to replace and so on, usually need to be replaced every 3 – 6 months to ensure that the filtration effect.
PP cotton filter element is characterized by low cost, good filtration effect and easy replacement.
Activated carbon adsorption:
Activated carbon cartridge plays a very important role in water purifier.
It has a rich pore structure and can adsorb foreign colors, odors, residual chlorine, organic matter and other harmful substances in the water.
The adsorption principle of activated carbon is to use the micropores and mesopores on its surface to physically adsorb substances.
Common activated carbon is coconut shell activated carbon, fruit shell activated carbon and coal activated carbon, etc.
Activated carbon cartridges generally need to be replaced regularly to prevent secondary pollution caused by adsorption saturation.
Reverse osmosis filtration (RO):
reverse osmosis technology is currently one of the most advanced and effective filtration in the water purifier.
It relies on the semipermeability of the reverse osmosis membrane, under pressure.
so that the water from the side of the high concentration to the side of the low concentration of osmosis, while the dissolved salts in the water, heavy metal ions.

Ultra-filtration:
Ultra-filtration water purifier adopts ultra-filtration membrane for filtration, and the filtration precision of ultra-filtration membrane is generally between 0.01 – 0.1 micron.
It can remove macromolecular organic matter, colloids, bacteria, viruses, etc.,
but the removal effect on dissolved salts and heavy metal ions is relatively limited.
Ultrafiltration water purifier does not require electricity, relying on water pressure for filtration, with low energy consumption, large water output.
