According to the different control objects, clean rooms can be divided into two categories: industrial clean room and biological clean room. Industrial clean rooms are mainly used in electronics, aerospace, aviation, machinery, energy and other industries, while biological clean rooms are mainly used in medical, biopharmaceutical, food, cosmetics and other businesses. For the two types of clean rooms, clean room design is also different.

To purify the object

Dust and particles in industrial clean rooms are only polluted once, while living particles such as microorganisms and germs in biological clean rooms continue to grow and reproduce, which will induce secondary pollution. Therefore, in the design of clean room, the process clean room should focus on the control of the concentration of harmful particle size, and the biological clean room should focus on the control of the generation, reproduction and transmission of microorganisms, and control of its metabolites.

The purification measures

In the design of clean room, the design of industrial clean room should focus on middle and high school filtration, while the design of biological clean room mainly focuses on filtration and sterilization, eliminating the conditions of microbial growth, controlling microbial growth, reproduction and cutting off the transmission of microorganisms.

The architectural design

The main control object of the industrial clean room is dust, so when the clean room is designed, the materials used do not produce dust, dust, friction resistance. The main control object of biological clean room is bacteria, so when the clean room is designed, all materials should be resistant to water and rot, and cannot provide conditions for microbial growth and reproduction.

Test design

In the design of the clean room, the industrial clean room should be equipped with a particle counter for the detection of instantaneous dust particles, and the biological clean room is equipped with a petri dish. After 48 hours of culture, the number of colonies can be read, but the instantaneous value can not be measured.

People flow and logistics design

In the design of clean rooms, a sterilization process should be added for biological clean rooms, while industrial clean rooms are not required. Before people, articles and air enter the biological clean room, sterilization should be carried out. The air shower and clean clothes are necessary in the clean room.
