What is a reverse osmosis water purifier?

Reverse osmosis water purifier is a machine that mainly uses the reverse osmosis principle for water treatment. The following is a detailed explanation of reverse osmosis water purifier:

1. Definition

Reverse osmosis is a process that uses a pressure higher than the osmotic pressure as a driving force, and uses the selective permeability of a selective membrane (i.e., a semi-permeable membrane) that can only pass water but not solutes to separate water molecules from solutes in the water body. Reverse osmosis water purifier is based on this principle, filtering tap water or other water sources through a reverse osmosis membrane to obtain pure water.

2. Working principle

The working principle of reverse osmosis water purifier is relatively simple but efficient. When tap water enters the water purifier, it will first pass through a pretreatment system to remove suspended matter, large particle impurities, residual chlorine, etc. in the water to protect the reverse osmosis membrane from damage. Subsequently, the water will enter the reverse osmosis membrane assembly. Under the action of pressure, water molecules are forced to reverse through the semipermeable membrane, flowing from the high concentration side to the low concentration side, while most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane and are retained on one side of the membrane, thereby achieving water purification.

III. Technical features

High-efficiency filtration: The pore size of the reverse osmosis membrane is extremely small (usually 0.0001 microns), which can effectively remove various harmful substances in the water and ensure the quality of the water.

High water quality: After the water is filtered through the reverse osmosis membrane, the conductivity of pure water is usually low (such as less than 5μs/cm), which meets the national laboratory level 3 water use standard. If further processed, such as atomic-level ion exchange column circulation filtration, the water resistivity can reach 18.2MΩ·cm, exceeding the national laboratory level 1 water use standard.

Wide application: Reverse osmosis water purifier is not only suitable for the purification of household drinking water, but also can be used in commercial places, industrial water use and other fields to meet various water quality requirements.

4. Advantages and Disadvantages

Advantages:

Good filtering effect: It can remove various harmful substances in the water and ensure the safety of water quality.

Easy to use: Generally adopts automatic operation mode, no manual operation is required.

Fast water output speed: Direct water output without waiting.

Long life: The core component reverse osmosis membrane has a long service life, generally up to 3-5 years or even longer.

Disadvantages:

The taste of the water is slightly worse: Because some minerals and trace elements in the water are filtered out, the taste of the water may be slightly worse.

The filter element needs to be replaced: The filter element needs to be replaced regularly to ensure the water purification effect and service life.

A certain amount of wastewater will be generated: A certain amount of wastewater will be generated during the filtration process.

High price: Compared with traditional water purifiers, the price of reverse osmosis water purifiers is higher.

5. Application scenarios

Reverse osmosis water purifiers are widely used in various scenarios that require high-quality water sources, such as household drinking water purification, bottled water production, community direct drinking water supply, electronic industry high-purity water preparation, pharmaceutical industry water purification, chemical industry water treatment and seawater desalination, etc.

In summary, reverse osmosis water purifier is an efficient and reliable water treatment equipment that can provide users with safe and pure drinking water and water quality for other purposes. When selecting and using it, comprehensive consideration should be given to actual needs and water quality.
