Gopani’s Oil Adsorption Logs are made from polypropylene melt blown microfiber and felt media. The log is surrounded with a heavy polypropylene mesh cover and has a polypropylene center core for rigidity. These logs can either be inserted inside a filter bag or can float on top of oil contaminate drums or vats. The unique design enhances the media’s ability to “wick” the free oil and grease from the contaminated liquid.
