Quality is not injected into the product through quality inspection, but is given by design. To obtain a good design, it is necessary to increase the awareness of the product and the control of the whole process of production. Purified water equipment manufacturers believe that the quality of purified water equipment factors, mainly include the following:
1. "Dead Angle": Dead Angle Inspection is an important part of the installation confirmation of purified water equipment. In purified water equipment, the presence of any dead angle may cause pollution of the entire system. Research shows that the "3D" rule is more in line with the microbial control requirements of clean fluid process systems. The "3D" rule of dead corners is mainly applicable to purified water systems that require microbial load after RO. For newly-built purified water equipment, the whole system should meet the "3D dead angle" design rules as far as possible.
2. "Indicates roughness": The surface roughness of purified water equipment shall meet the actual requirements of production, cleaning and sterilization of purified water equipment. The treatment of inner surface roughness of stainless steel pipes, pipe fittings and other raw materials has a very important influence on equipment. Through polishing treatment, the contact area of the inner surface of the system can be greatly reduced, which will help reduce the residual amount of purified water equipment and the risk of impurity adhesion; it will help the inner surface of purified water equipment to be smoother and easier to clean; It helps to prevent the settlement and reproduction of microorganisms, and provides a reliable guarantee for the satisfaction of the microbial limit of the equipment.
3. "Slope": Gravity is an effective way to promote the exhaustion of purified water equipment. Slope inspection is another main content of the installation confirmation of purified water equipment. Although most purified water equipment is sterilized by ozone or hot water, due to the principle of equipment maintenance risk and location discharge, the design and installation of the whole purified water equipment is also recommended to follow the principle of "full drainage by gravity.
4. "Modular Design": During the installation and construction of purified water equipment, SKID modular assembly has been widely used. Modular assembly is conducive to the realization of factory performance testing, saving floor space, reducing production costs, stable product quality and easy to operate, fully in line with the production management concept of modern biopharmaceutical enterprises.
