Water treatment refers to the purification of polluted industrial wastewater or river water through a series of water treatment equipment, and the removal of some substances that are not required for production and life in the water through physical and chemical means, so as to meet the water quality standards stipulated by the state process.
Water not only has an important impact on our life and health but also has an important impact on many aspects such as industrial production. At present, people’s requirements for water quality are constantly improving, so water treatment technology has emerged. With the continuous advancement of current technology, many new technologies have emerged.
In water treatment technology, the softening method is the first method used, which is to remove or reduce the hardness in the water, so as to soften it, but it will not have any impact on the water quality, and will not improve it.
Distillation and boiling
The boiling method is very simple, that is, to boil it before drinking it. This method is also used at present. It can kill bacteria, but it is powerless to chemicals and heavy metals, so it is not very safe. The distillation method is to boil the water and collect the liquid. This process is very safe, but it also has disadvantages. Distilled water does not contain minerals, and the extraction cost is too high.
Magnetization, mineralization and electrolysis
The magnetization method, which uses the magnetic field effect to treat water, is not widely used at present and is only used in medicine. The mineralization method is not recognized by the country at present, because heavy metals and chemical substances cannot be removed, and the dead bacteria still remain in the water, which is not clean. The benefits of electrolysis, in which purified water is electrolyzed, are not yet clear and are still being explored.
Activated carbon adsorption
This technology currently has three forms, namely granular activated carbon, silver-infiltrated activated carbon, and fiber-activated carbon. Each form is different. The technology of fiber-activated carbon is more advanced, and the effect of water purification is ideal.
RO reverse osmosis membrane
This technology is currently more popular in the world. It can be used to make water purifiers and other equipment, which improves the water quality and tastes quite good. It can also be used in the beauty industry, as well as in some hotels, hospitals and other fields. The use is also quite large.
EDI ultrapure water technology
Just because the traditional ion exchange has become increasingly unable to meet the needs of modern industry and environmental protection, the EDI technology that combines membrane, resin and electrochemical principles has become a revolution in water treatment technology. The regeneration of its ion exchange resin uses electricity instead of acid and alkali, so it meets the environmental protection requirements of today’s world.
