Material cleaning method for use in e.g. painting field, involves processing cleaning solution by adding flocculent using flocculation unit, and filtering solution to recover residue from reusable cleaning solution

摘要

The method involves contacting material to be cleaned with a cleaning solution e.g. ecological cleaning water, and isolating the cleaning solution at an end of the cleaning material. The solution is processed by adding flocculent using a flocculation unit. The solution is filtered to recover residue or paint pigments from the reusable cleaning solution. An independent claim is also included for a device for cleaning a material contaminated by a water thinnable paint, ink and grease.
