OilFree (HRM) Filter Bags

It has high hydrocarbon adsorption capacity per unit weight which makes it ideal for use as a coalescer, and as a preconditioning stage to the OilFree HRM technology resulting in attractive cost to treat values. The unit is often installed as the primary stage filtration device in applications where an Oily Water Separator or API separator is too large or too expensive. OilFree HRM Filter Bags are used in filtration systems for water contaminated with light oils, heavy oils, mixed waste streams composed of solvents, emulsions and soluble hydrocarbons.
