Abstract
A commercial dry-cleaning solvent filter apparatus is configured to filter and decontaminate a used dry-cleaning solvent in a specialized multi-level filtration container to enable environmentally-friendly reuse of the used dry-cleaning solvent in a commercial dry-cleaning machine after a novel decontamination process. The commercial dry-cleaning solvent filter apparatus incorporates multi-level gravity feed filtration chambers filled with a unique multi-metallic and multi-chemical filtration “clay” agent in multiple stages for comprehensive decontamination of the used dry-cleaning solvent. The filtered and decontaminated used dry-cleaning solvent is reusable and can be pumped back into a dry-cleaning solvent tank internal to the commercial dry-cleaning machine. The reuse of the dry-cleaning solvent reduces the need for frequent solvent replacements. The movement of the used dry-cleaning solvent into or out of the commercial dry-cleaning machine and the commercial dry-cleaning solvent filter apparatus is further assisted by a motorized pump mobilizing the used dry-cleaning solvent.
