The company is using the filter shell with pecan shells as raw material, crushing, air rotary, polishing, steam cleaning, filtering and other processing, the appearance of shiny, brown. This filter tenacity, wear compression, absorption ability, anti-oil, non-caking, non-perishable, it is a wide selection of oil, metallurgy, environmental protection, chemical and other industries. Based on the thickness of the oil filter shell pecan shell particles appearance was brown, no rot, no spots, toughness and wear resistance. Mainly used in highly automated control water filters, water filters, filters, etc. into the well. Oilfield, oil refineries, petrochemical projects and other environmental projects essential oil-water separator water purification materials. It has the advantage that resistance. One: Features 1, with a wide range of microporous interception in strong oil and suspended solids removal. 2, has a multi-row and different particle sizes, the formation of deep bed filtration, enhanced degreasing capacity and filtration rate. 3, having a hydrophobic lipophilic and appropriate proportion backwash, regeneration and strong. 4, hardness and corrosion by the special treatment is not easy, do not replace the filter, add only 10%, reducing maintenance and repair time, improve utilization. Two: Use 1, oily wastewater treatment, to oil and suspended solids. 2, industrial oil industrial water treatment, to oil and suspended solids. 3, domestic water and industrial water treatment, removal of suspended solids, and improve water quality. Three: Technical specifications Specification test data test data test items 90-96% oil removal backwashing strength 25 m3 / m2.h suspended solids removal 95-98% water flushing pressure 0.32mPa filtration rate 20-25m / h maintenance mode add 5-10% annually density 1.26g / cm3 bulk density of 0.85g / cm3 four: Packaging: Non-toxic bags. Net weight: 25kg.
