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
