Walnut shell filter media

 

Walnut shell filtering material is made of high quality walnut shell, through crushing, polishing, steaming and washing, high temperature treatment, two times screening processing.Walnut shell filtering material with high hardness, wear resistance, good pressure resistance, resistance to pressure of 23.4kgf, stable chemical property, do not dissolve in acid and alkali , excellent absorption sewage interception capability, adsorption rate is 27 - 50%, with good hydrophilicity, oil  resistance, etc..

 

Due to Walnut shell filtering material  with the proper hardness, ideal density, porous and versatility, and processed by special physical and chemical treatment ( remove the pigment, fat, oil, electricity), make it has the strong performances of oil removal,solid particles removal, easily backwashing etc in water treatment. walnut shell has been widely used in oil field wastewater treatment, industrial wastewater treatment and water treatment. It is the new water treatment material to replace quartz sand filter, improve water quality, greatly reduce the cost. .
