What are the application scope of purification engineering

by:PHARMA     2022-10-31
The four major areas with a wide range of purification engineering applications mainly refer to: electronic factories, GMP workshops, operating rooms, and biosafety laboratories. Different fields have different requirements for purification control systems. At the same time, the control standards in these fields can be widely used in other industries. For example, the control system of the purification project of the electronic factory can be used in the PCB production workshop, electrical appliances, injection molding pharmaceutical cleanroom, etc. The control characteristics of purification projects in the four major fields are as follows: 1. The cleanliness of electronic factories directly affects the quality of electronic products. Primary air supply and secondary air supply systems are used, and FFU fan filter units are used in large quantities to purify the air layer by layer to achieve the goal of changing clothes. Room level 8 purification, corridor level 7, production pharmaceutical cleanroom level 6, some need between level 5 or level 4, and static acceptance is required after the project is completed. 2. The three goals of GMP workshop purification control are cleanliness. The airlock room widely uses six-level standards to control no cross-contamination in the clean room; CFU refers to the number of viable bacteria in the clean room; the project needs to obtain national GMP certification; Three goals can be a qualified purification project. The engineering system needs to use local 5 poles of the duty fan, which is dynamically monitored and used after static acceptance. 3. The operating room is strictly controlled. The MAU+AHU system is adopted, the air supply ceiling is 3m*3m, and the purification level is thousands of grades. The acceptance criteria are static acceptance and dynamic acceptance of temperature, humidity, and CFU. Under normal circumstances, the infection rate of patients during surgery is 25%. According to statistics, the current surgical infection rate is 10%-15%. Many yiyuan use the daily surgical infection rate as an excellent indicator for evaluating operating room purification projects. 4. Characteristics of biosafety pharma machinery purification engineering control my country has formulated relevant safety regulations. The engineering purification pharma machinery adopts biosafety isolation suits and independent oxygen supply systems. Press the secondary barrier system to ensure personal safety, and formulate comprehensive regulations for the purification management of biosafety laboratories.
