Walnut shell Filter media uses a special processing of walnut shell as raw materials, walnut shell media has a strong adsorption capacity and filter backwash regeneration, compression capability, chemical stability (not readily available in acid, alkali dissolved in solution), high hardness. Walnut shell has good wear resistance, long-term use without having to change the adsorption ability Sewage Interception) (absorption rate of 25-53%), good hydrophilic, anti-immersion. A result of the filter is slightly larger than the proportion of water, an-washing to facilitate regeneration of its most important feature is the direct use of filter backwash water before, and without using gas source and chemical agents, low operation cost, easy management, anti-Rinse low strength, the effect is good, filter non-perishable.
