The Difference Between UF Machine And RO Machine

The common water filtration methods in the market are microfiltration, ultrafiltration, nanofiltration and RO (Reverse Osmosis). The filtration capacity is as follows:

Microfiltration can only be simple filtration, and it will not be considered basically. The nanofiltration filter is between ultrafiltration and reverse osmosis, and it is also relatively defective. Therefore, the market mainly uses ultrafiltration and reverse osmosis.

Ultrafiltration water purifier:

Ultrafiltration water purifiers use ultrafiltration technology to purify water. The difference with other water purifiers is the use of ultrafiltration membranes. The ultrafiltration membrane is a microporous membrane with a uniform pore size and a nominal pore size range of 0.01-0.001 micron.

Ultrafiltration water purifier principle:

The ultrafiltration membrane has a very small pore size, which is about 1% of a single hair. Therefore, bacteria in the water and colloids, rust, suspended solids, sediment, and macromolecule organic matter, which are much larger than bacteria, can be passed through. The ultrafiltration membrane is trapped to achieve the purification process.

Reverse osmosis water purifier:

RO water purification principle is also called RO reverse osmosis principle. RO reverse osmosis is a kind of pure water machine that can directly drink humans by adding filtered water to the raw water through the current international popular reverse osmosis method. Also called terminal water purification equipment.

Reverse osmosis water purifier principle:

Reverse osmosis water purifier exerts a certain pressure on water, which causes water molecules and ionic mineral elements to pass through a layer of reverse osmosis membrane. Most organic substances dissolved in water and bacteria and viruses cannot pass reverse osmosis membranes. , thus strictly separating the pure water from the impervious concentrated water, the pore size of the reverse osmosis membrane is only 0.0001 micron, which is equivalent to one millionth of a hair filament. The smallest viruses have a size of 0.2 microns or more, so they cannot pass through reverse osmosis membranes.

Questions about RO:

Q: The RO machine filters all the minerals in the water. Is it bad for the body to drink this water?

A: The water does contain many substances, but the content of these substances is minimal. The amount of minerals in the water is more than what you eat. Therefore, drinking pure water is not healthy, but it is only self-interference.

Q: RO opportunity to produce wastewater? What are the causes of these waste waters?

A: There are two main sources of wastewater: flushing wastewater and filtering wastewater. Rinse waste water is used to flush RO membranes. It is usually flushed when the machine restarts water production. This prevents the RO membrane from being plugged and prolongs the service life of the RO membrane. Filtration waste water is filtered by tap water. Membrane intercepted retentate. According to the ratio of 1:1 pure wastewater, if 15L of pure water is used in one day (basically satisfied with drinking water and cooking), 15L of wastewater will be produced, with a total water consumption of 30L, and a total of 0.9 tons of water for 30 days a month (30L*30=900L) ).
