Walnut shell filter media has strong adsorption capacity. At present, as a new generation filter material to replace quartz sand filter material, improve water quality and greatly reduce the cost of water treatment, it is widely used in oilfield oily sewage treatment, industrial wastewater treatment and civil water treatment.
1. High hardness, wear resistance, and good pressure resistance.
2. Easy to dissolve in acid and alkali solution.
3. Strong adsorption and dirt-cutting ability. Its adsorption rate is 27-50%.
4. Good hydrophilic, resistant to oil immersed.
5. Easy to backwashing and regeneration. It can be directly used for backwashing before filtering.
