[Continuous sterilization of peritoneal dialysate using ultraviolet rays].

A unit for continuous ultra-violet sterilization on the basis of a mercury-UV low-pressure lamp was devised and tested. It differs from the known analogs in the capacity of separating into layers of the monolithic flow of a solution and of using the entire arsenal of direct rays emitted by the source. The output is 400 ml/min. The irradiation dose exceeds 163 times the optimal one for spores. The authors provide a mathematic depiction of the unit operation. A linear relationship was established between the growth of optical density of the solution and the irradiation dose. About 100 tons of the peritoneal and replacement (for hemofiltration) solutions were sterilized and utilized.
