Background A beverage factory needs to pre-treat raw water (containing sediment and algae) to ensure that the SDI of the subsequent reverse osmosis membrane (RO) inlet water is ≤3. Solution Pretreatment process: multi-media filter (quartz sand) + fiber ball filter (ultrafine fiber ball) two-stage filtration. Precision control: The fiber ball filtration accuracy is improved to …

Background A city sewage treatment plant needs to treat the secondary effluent (SS≤30 mg/L, COD≤60 mg/L) to the reuse standard (SS≤5 mg/L, COD≤20 mg/L) for green irrigation. Solution Combined process: fiber ball filter (modified polyester fiber ball) + ozone oxidation to achieve deep filtration and organic matter degradation. Operation parameters: filtration speed 10 m/h, backwash …

A petrochemical plant produces a large amount of oily wastewater (oil content ≤500 mg/L, suspended solids ≤300 mg/L) during production. Traditional sand filters are prone to clogging and backwashing is frequent, with high operating costs. Solution Process design: Use fiber ball filter (polypropylene fiber ball) as the secondary deep filtration unit, connected to the flotation …

The fiber ball filter is a highly efficient water treatment equipment. Its core filter medium is elastic fiber balls, which have the characteristics of large porosity, high specific surface area, strong adsorption capacity and chemical corrosion resistance. The fiber ball filter removes suspended matter, colloids, oil and microorganisms in the water through physical interception and …
