Public System

The public system needs to provide a stable and clean environment for production. For water, gas, compressed air, inert gas, etc., it should meet the cleanliness requirements of the corresponding pharmaceutical process, GMP and the corresponding guidelines and regulations. In the pharmaceutical industry, the water needed for production is specially treated. In order to ensure the plant is clean or the fermentation process is pollution-free, the gas needs to be sterilized and filtered.

The stable public system provides a strong support for continuous production. Water, gas and air environmental systems in production are subject to special treatment to meet their own characteristics and the requirements of GMP and corresponding guidelines and regulations.
Water for production: purified water, water for injection, water for sterilization, etc.

Among them, a 0.2 m hydrophobic ventilation filter is installed at the breathing mouth of the distilled water storage tank. Fill with nitrogen and add a 0.2 m hydrophobic filter for filtration.
The air conditioning system shall control the microorganisms within the prescribed standards by means of sterilization, sterilization and disinfection.
Gas filtration: biological fermentation process, enzyme catalysis process and cell tissue culture process of biopharmaceutical, which requires sterile and impurity free purified air, or purified nitrogen, or purified carbon oxide and other inert gas or nutrient gas. The required compressed air should be sterilized and filtered. Try to choose hydrophobic filter materials, such as PP, PTFE, PVDF, GF, etc.

For example, fermenter air filtration:
Prefilter PP film 1-3 m nominal accuracy, about 10 m absolute accuracy; 10 m absolute precision steam particulate removal filter made of stainless steel sintered material; 0.22 mPTFE membrane sterilizing filter.
All gas sterilizing filter elements are required to undergo 100% integrity test before leaving the factory. During use, the integrity test should be carried out on the filter element to ensure that the test value of the filter element is within the standard value range and that the filter element is in good condition to achieve the purpose of sterilizing.
