Efficient modified fiber ball filler is made of modified fiber Sizha knot, it applies to the fine filter oily wastewater, but also for other industrial wastewater fine filtration. Fiber ball surface after modification of oils and organic adsorption capacity enhancement; modified fiber ball new sterilization method, run-time filtering layer porosity decreases along the flow direction, forming a more ideal filter on the big small pore distribution, better filtration; filtration rate is high, up to 25-30m / h. Just fill the filter about 10%, without replacement. Specializing in the production of water supply material products of economic entities. It is suitable for fine filtration of oily wastewater, but also for other industrial wastewater fine filtration. Remove oil and modified fiber ball mechanism of organic matter: direct interception, inertial interception and electrochemical adsorption. Filter before the water oil ≤ 15mg / L, suspended solids ≤ 10mg / L; filtered water oil ≤ 5mg / L, suspended solids ≤ 2mg / L. Fiber ball surface after modification of oils and organic adsorption capacity enhancement; modified fiber ball new sterilization method, run-time filtering layer porosity decreases along the flow direction, forming a more ideal filter on the big small pore distribution, better filtration; filtration rate is high, up to 25-30m / h. Just fill the filter about 10%, without replacement. Modified fiber ball with ordinary fiber ball biggest difference in the result which is different from textile dyeing ---- poor polymer modified fiber tows fine made of hydrophilic and oleophobic, on oily wastewater treatment has a good effect, high precision, easy to wash, long life cycle, it is widely used in oil, petrochemical processing, printing and dyeing wastewater treatment.
