The 37BGPP is an industrial super fine perlite precoat filter aid. This perlite has expanded lightweight bubbles that divides small solid particles from liquids, making it suitable as a filter aid that creates favorable flow rates. The filter aid has a filtering layer that prevents the solids that are being removed from fastening to the septum. It works well as a pre-coat filter aid, as the expanded perlite creates low bulk density with larger volumes. Perlite filter aids are applicable with pressure and vacuum filtration equipment. They are often used to filter liquid in the food, pharmaceutical, and beverage sector.
