Walnut Shell is specifically used within enclosed Walnut Shell Filter systems due to its hardness, porosity and density.
NutFilter® helps remove oils, fats, grease and solid particles. Walnut Shell Media is specifically used in water treatment equipment within refineries and petrochemical companies to improve the quality of their waste water.
Walnut Shell Filters are designed to remove fine solids and hydrocarbon liquids from water as a secondary or tertiary stage of water treatment.
Oily water is introduced into the vessel and distributed to ensure even flow throughout the vessel.
