いなどの難点含有する装置ｉもある。Equipment that has traditionally been used to produce sterile water for use in the medical field includes distillation equipment, boiling sterilizers, and ultraviolet sterilizers, but the energy and equipment costs required for operation are high. Some devices have drawbacks such as insufficient water sterilization effect, and some devices have drawbacks such as being able to remove colloidal substances and bacteria but not pyrogens.

ールの開発が強く要望されていた。Under these circumstances, the inventors of the present invention have developed a precision filtration system that overcomes the drawbacks of conventional water purification equipment, has low equipment costs and energy costs during operation, has a simple structure, is less likely to break down, and is highly reliable. We thoroughly investigated the methods for creating a pure water production device and created a hollow fiber filtration module that was used as a porous polyolefin hollow fiber filtration membrane with a laminated structure in which micropores were interconnected from the inner wall surface of the hollow fibers to the outer wall surface. However, since the porous polyolefin hollow fibers used do not have bactericidal properties, bacteria may accumulate inside the filtration module during long-term operation. There is a risk of gradual accumulation and proliferation, and from the standpoint of safety and hygiene, there has been a strong demand for the development of a porous polyolefin hollow fiber module that exhibits excellent sterilization properties when used in this one-percent module.

ルに関する。The present invention has a sterilizing property in which micropores are interconnected from the inner wall surface of the hollow fiber to the outer wall surface to form a single layered structure, and a thin porous silver film is deposited on the surface layer of the single porous polyolefin hollow fiber. This invention relates to a filtration module using porous polyolefin hollow fibers.

又は両面に対しておこＴ、ｃい。A thin layer of porous silver is applied to the surface layer of the porous polyolefin hollow fiber! ! For example, a vacuum evaporation apparatus can be used as a method for completely forming and providing permanently sterilizing fully porous polyolefin hollow fibers. According to this method, a thin film of metallic silver can be extremely firmly adhered to the porous surface of the outer wall of the porous polyolefin hollow fiber, and permanent bactericidal properties can be imparted to the porous polyolefin hollow fiber. In this case, the silver vapor deposition treatment is performed on one or both sides of the outer surface of the porous polyolefin hollow fiber.

When the number is less than 2, a porous silver film is formed. If the VC is more than 15.9/m2, it becomes difficult to form a porous silver film, making it difficult to obtain the sterilizing porous polyolefin hollow fiber module of the present invention.

知ることができる。Silver exhibits excellent bactericidal properties, and when used with appropriate methods, silver has the ability to purify water approximately 10 million times its weight, and water contained in a silver container remains sterile. This fact can be fully understood from the fact that it is known to bite.

Any type of module may be used as long as liquid or gas is directed toward the wall surface or the inner wall surface area or the outer wall surface.
