Industrial Cleanroom

Biological Cleanroom

Research object (main)

Dust, particles only onc

Hazards to process production

Living particles such as microorganisms and germs constantly grow and reproduce, which will induce secondary pollution (metabolites, feces).

Control methods purification measures

The main measures include: eradication of microbial growth conditions, control of microbial brauchery, reproduction and cut off microbial transmission routes, filtration and sterilization.

Control objectives

Control the concentration of harmful particle size

Control the generation, reproduction and spread of microorganisms, as well as their metabolites.

Hazards to process production

Even a single dust particle on critical components can cause significant damage to the product.

Harmful microorganisms cannot cause damage until they reach a specific concentration threshold.

Requirements for clean room building materials

All materials (cleanroom walls, ceilings, floors, etc.) must not produce dust, accumulate dust, and must be wear-resistant.

All materials must be resistant to water and corrosion and must not provide conditions for microbial reproduction.

Control over the entry of persons and objects

Personnel entering must change shoes, change clothes, and pass through air showers. Items entering must be cleaned and wiped. Personnel and materials should be separated and decontaminated independently.

Personnel entering must change shoes, change clothes, and pass through air showers. Materials entering require cleaning, disinfection, and sterilization. Air must be filtered and sterilized, with personnel and materials routed separately for decontamination.

Detection

Dust particles can be detected by a particle counter and then displayed and printed.

Microbial detection cannot measure instantaneous values, and colony counts can only be read after 48 hours of culture.
