Production technology: walnut shell filter material is a kind of water treatment filter material made of high-quality walnut shell as raw material through crushing, polishing, cooking, drug treatment and twice screening.

Appearance: beautiful luster, brown, made of high-quality hickory shell, processed by crushing, air spinning, polishing, steaming and washing, screening, etc.

Performance: The production process of this tough and degreased walnut shell filter material has the advantages of wear resistance, pressure resistance, strong adsorption capacity, no caking, no spoilage of walnut shell abrasive manufacturers, insolubility in acid and alkali, good hydrophilicity and oil immersion resistance.

Uses: It is an ideal filter material for oily sewage treatment in oil fields, smelting, environmental protection, chemical industry and other industries. More importantly, walnut shell filter material has been widely used in oil field oily wastewater treatment, industrial wastewater treatment and civil water treatment. It is a new generation of filter material to replace quartz sand filter material, improve water quality and greatly reduce water treatment cost.
