What is the scope of application of purification engineering?

Purification engineering: Control the cleanliness, temperature and humidity of the atmosphere that products (such as silicon chips, etc.) are exposed to, so that the products can be produced and manufactured in a good environmental space. The design and construction process of this environmental space can be called a purification project. The products are widely used in electronics, electrical appliances, medicine, food, scientific research and other industries, and have an overall system service system for guarantee and rich production experience.
The following describes the scope of application of purification engineering:
1 Microelectronics industry
　The microelectronics industry is an industrial clean industry that currently has high requirements for clean rooms. In addition, the production of liquid crystals and optical fibers in modern industries also has cleanliness requirements.
2 Pharmaceutical industry
(1) Pharmaceutical production my country's "Management of Pharmaceutical Production" (also known as GMP) has been implemented nationwide, and different cleanliness requirements corresponding to the process have been proposed for the production environment.
(2) In the leukemia treatment rooms, burn wards, and surgical operating rooms of hospitals, corresponding clean technologies are used according to conditions to prevent bacterial infections in the air and play an environmental protection role for treatment.
(3) Medical science experiments. For the breeding of laboratory animals, genetic engineering and other disciplines experimental projects, there should also be a clean environment in order to achieve effective results.
3 The aseptic packaging of food is also superior to high-temperature sterilized canned food in maintaining food color, aroma, taste and nutrition.
4 Others, such as aerospace industry, precision machinery industry, instrumentation industry, fine chemical industry, etc., all use clean technology.　　　
With the development of technology, especially in the semiconductor industry, many production steps must be carried out under clean room conditions. (Purification engineering technology) The application of clean rooms is becoming more and more important.
