Wuhan filtered source brand walnut shell filter manufacturers ~

Walnut shell filter because of their hardness, ideal weight, porous and multi-faceted, and by the special physical and chemical treatment (pigments, fat, oil, electricity and pay the ion removal and clean), it has a strong in Water Treatment degreasing properties, in addition to solid particles, easy backwashing excellent performance, walnut shell filter has been widely used in oily wastewater treatment, industrial wastewater treatment and residential water treatment. Replace the quartz sand, improve water quality, water treatment significantly reduced the cost of a new generation of media. By the Beijing Forestry University, Shandong Academy of Sciences Test Center, Jiangsu Institute of Environmental Protection determined compression capability of a particle size of 1.25-1.60mm walnut shell particles, the average compression limit of 0.2295KN (23.40kgf). Particle size of 0.80-1.00mm walnut shell particles, the average compression limit of 0.165KN (16.84kgf). Chemically stable, non-toxic substances, acids, alkalis, dissolved in water is very small, walnut shell loss in hydrochloric acid solution was 4.99%, the loss in sodium hydroxide solution was 3.8% without causing deterioration of water quality phenomenon. Main specifications: 0.5-0.8mm, 0.8-1.25mm, 1.2-1.6mm, 1.6-2mm main technical indicators: Test items Test data test data test items 90-95% oil removal backwash intensity 25m3 / m2.h suspension removal of 95-98% water flushing pressure 0.32mPa filtration rate 20-25m / h per year in maintenance mode to add a 5-10% density of 1.25g / cm3 bulk density of 0.8g / cm3
