Water for injection equipment pretreatment to meet the following requirements
① purified water pretreatment equipment can be equipped according to the quality of raw water, required to meet the drinking water standards first.
②Multi-media filters and water softeners require automatic backwash, regeneration, discharge.
③ Activated carbon filter for organic matter concentration, in order to prevent bacteria, bacterial endotoxin contamination, in addition to the requirement of automatic backwash, can also be used for steam sterilization.

⑤ As the ultraviolet light excitation of the 255nm wavelength light intensity and time inversely proportional to the requirements of the instrument to record the time and the intensity of light meter, the immersed part of the water using 316L stainless steel, quartz lampshade should be removable.
