METHOD AND PRODUCT FOR CLEANING HOLLOW FIBER MATERIAL AND FILTER

摘要

A peracetic acid disinfectant has been shown to be effective in cleaning particulate inorganic materials such as calcium and magnesium from fibers and filters. The disinfectant is used in solution form in a method allowing filters, especially those made up of polysulfone, to be soaked for at least 18 hours, preferably at least about 24 hours, and then reused. This method has shown filters cleaned by the solution to have a reuse life in excess of 30 % and up to about 60-80 % of the original life of the filters. The peracetic acid based disinfecting solution may be used to clean polysulfone filters in both hollow fiber and pleated form.
