ABSTRACT:
A method for in-line filtration of flowing liquids wherein composite filtering of mechanical entrapment type and of absorptive character is implemented in relative measures adapted to meet both flow rate and contaminant filtration requirements. The invention effects jointly operative steps of mechanical and absorptive oil-based contaminant removal with accommodation of desired flow rate of automotive coating liquid by a practice wherein these two filtration techniques are effected concurrently throughout a length of conduit assigned to filtering. The invention is practiced through the use of a fibrous body, comprised in first part of oil-absorptive fiber and in second part of fibrous matter substantially non-absorptive to oil contaminants, the second part fibrous matter being arranged to selectively entrap oil contaminants and prevent absorption thereof by such oil-absorptive fiber.
