Product Details
Walnut Shell Filter Material Walnut shell filter uses a special processing of walnut shell media has a strong adsorption capacity and can filter backwash regeneration, compression capability , chemical stability (not readily available in acid, alkali dissolved in solution), high hardness. 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 slightly larger than the proportion of water (1.225g/cm3), anti-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. Durable, and can according to the water quality requirements, adopt a single-stage or two-stage tandem use.Product technical specification:ProjectTest dateProjectTest dateOil removing rate90-96%Backwashing intensity25m3/m2.hSuspensions removing rate95-98%Water flushing pressure0.32mpaFiltration rate20-25m/hMaintenance modeEvery year supplemented 5-10%density1.26g/cm3Stack density0.85g/cm3
