Many people know that water purifiers have filter elements, but I believe that they may not be able to accurately recognize them. Today we will understand and understand what the filter elements in our water purification system look like.
Polypropylene melt spray filter element
The melt blown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles through heating, melting, spinning, traction, and forming. If the raw material is mainly polypropylene, it can be called a PP melt blown filter element. It is not only used in water purification in large quantities. It also has outstanding chemical compatibility and is suitable for the filtration of strong acids, strong alkalis and organic solvents. Strong dirt holding capacity, long service life and low cost.
Secondary granular activated carbon
The pre-activated carbon particles are coarser and are used to adsorb impurities, heavy metals and other harmful substances in the water.
Three-stage compressed activated carbon filter element
is to remove residual chlorine in water, remove peculiar smell, and remove organic compounds. Can effectively remove trihalomethanes. In addition, it also has a highly effective filtering effect on solid substances such as spores, lead and microorganisms in the water.
Four-stage RO reverse osmosis membrane
Reverse osmosis is to separate the solvent (usually referred to as water) in the solution through a reverse osmosis membrane (a kind of semi-permeable membrane) with sufficient pressure. The direction is opposite to the permeation direction, and the reverse osmosis method greater than the osmotic pressure can be used for separation. , Purify and concentrate the solution. Using reverse osmosis technology can effectively remove impurities such as dissolved salts, colloids, bacteria, viruses, bacterial endotoxins and most organic matter in the water.
Five-stage post activated carbon
The rear activated carbon filter element is the last process in the filter element filtration. The main function is to purify the water quality and improve the taste of water. Generally, coconut shell activated carbon is used for post activated carbon. This kind of coconut shell activated carbon is mainly made of the above-mentioned coconut shell as raw material. After a series of precision processing, the appearance that we can see is black and granular. This activated carbon has strong adsorption capacity, long service life, and wear resistance. The purified water equipment has a rear activated carbon filter system that can deeply purify the water. The raw water is filtered through the middle layer of the water purifier. When it comes to the rear activated carbon filter, it can more thoroughly absorb the different colors and odors in the purified water. The taste of purified water also inhibits the regeneration of bacteria in the purified water, ensuring pure sweetness and deliciousness.
