High quality Walnut shell filter material
Introduce of walnut shell filter
Walnut shell , water treatment materials, filter materials.
Walnut shell filtering material is made of high quality walnut shell, throughcrushing, 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..
Advantages of walnut shell filter media :
1. Non-rot, no stains, tenacity, wearing compression (≤23.4kgf), anti-oil-filled, non-caking
2. Multiaspects and multipores, strong adsorption, high removing rate of oil and seston
3. Multi-edges, deep filtering, improve deoil capacity and filtering velocity
4. Easy counterflow, low couterflow strength (6.7L/Sm2)
5. No need to change all of the filter material, just need 5-10% supplement every year

Our factory using foreign advanced technology specialized in vitrified bond grinding wheel hole porosity materials - walnut shell grains. Compared with the old poreorming material- refined naphthalene, our product has uniform pores, and it is odorless, nonpolluting, easy to use, inexpensive andsafe. Moreover,The pore size of the grinding wheel can be arbitrarily selected. Thus, in10 years abroad, it has been widely adopted in abrasives industry.
