Do you know the filtration steps of pure water equipment? Now let's introduce it.

Water purification: Using water purification technology to remove a large amount of organic components, heavy metal ions, and harmful impurities, while retaining beneficial trace elements for the human body. Clear, sweet, and oxygen rich, it can be consumed directly and is called purified water.

Purified water: Using reverse osmosis technology to remove organic and inorganic components, heavy metal ions, harmful impurities, and minerals from water, it can be consumed directly and is called purified water.

Activated carbon is a type of carbon compound with well-developed micropores. It has a rich pore structure (1000m2 per gram), therefore it has strong adsorption performance. It is one of the commonly used water purification materials in water treatment. It can remove color, odor, organic matter, and residual chlorine from water, and change the taste of water.

The filtration accuracy of pure water equipment is generally 0.03-15 μ m. It is a membrane process driven by static pressure and separated by the screening effect of the screen mesh filter material. The microfiltration membrane has a relatively uniform porous structure. Under the action of static pressure difference, particles smaller than the membrane pores pass through the membrane, while particles larger than the membrane pores are trapped on the surface of the membrane, allowing components of different sizes to be separated.

Ordinary polypropylene and ceramic filters belong to the category of microfiltration, which can filter large particles such as sediment and rust in water.

The filtration accuracy is between microfiltration and nanofiltration, with a pore size range of 0.002 μ M-0.1 μ m. It is a pressure differential membrane separation technology, which filters raw water from the high-pressure end to the low-pressure end under pressure. Ultrafiltration can generally filter out harmful substances such as rust, sand, colloids, and high molecular weight organic matter in water, while retaining some beneficial mineral elements for the human body. It is a core component of the production process of mineral water and mountain spring water.

The accuracy of reverse osmosis filtration is about 0.00001 μ M. In theory, impurities (including harmful and beneficial ones) in water can be filtered out, and only water molecules are allowed to pass through. Purified water equipment is generally used for producing drinking purified water, industrial ultrapure water, and pharmaceutical ultrapure water. Reverse osmosis technology requires back pressure of raw water. The control system can be used for backwashing of reverse osmosis membranes, increasing their service life.
