Microplastic filtering system integrated with a prefiltering assembly, for a washing machine, such as a laundry washing machine

Abstract

A system includes a casing internally defining a filtering cavity and having an inlet leading into the filtering cavity and configured to be hydraulically connected downstream of a discharge pump and to receive a fluid containing microplastics. The casing also has an outlet configured to deliver the fluid contained in the filtering cavity, from which the microplastics have been substantially removed. A filtering assembly contained in the filtering cavity is crossed by the fluid entering the casing through the inlet and exiting through the outlet, thus internally trapping the microplastics. A compacting assembly is situated in the filtering cavity and configured for collecting and compacting the solid particles trapped by the filtering assembly. A pre-filtering assembly is configured to be fluidically connected upstream of a discharge pump to trap any foreign bodies that may be present in the microplastic-containing fluid.
