Modified Fiber Ball Filter Media,through the modification of its fiber surface, the adsorption capacity of oil and organic debris enhanced.Using the new sterilization method of fiber ball,the porosity of the filter layer along the flow direction became smaller within operating condition, so formed of the ideal filter under the state with the large distribution of small pores.It has well effects and high-speed of filter, up to 25-30m/h,and filter only need add about 10% per year without replacement.The modification fiber silks with hydrophilic,thinning oil, anti-wash regeneration performance, is better suited to deal with refined oil for the filtration equipment.
