TREATMENT METHOD OF METALWORKING FLUID AND CLEANSING SOLUTION AND TREATMENT SYSTEM THEREOF

摘要

A treatment method of metal working fluid and cleansing solution and a treatment system are provided to minimize the contamination of a membrane. An ozone apparatus produces ozone for sterilizing bacilli. An ozone injection apparatus(11) includes an ozone tube for guiding flow of ozone produced from the ozone apparatus. A pre-processing filter(20) removes minute metal chips from the cleansing solution of a cleaning tub. A thin type of oil separator(30) removes oil by combining oil particles of 10-20 micrometers with the filtered cleansing solution and metal working fluid. A condensing container(40) stores the mixing solution of the cleansing solution and the emulsified metal working fluid. A membrane filter(50) is immersed into the condensed mixing solution and filters the metal working fluid and particles.
