This kind at filing is made from some anti-corrosion. temperature-resisting and ageing resistance material among polyolefins and PA. mixing with hydrophile. absorbent. thermo-Axidative resistant auxiliary agents by wire drawing technology. Fix strand on center rope. it is in vertical radiate shape because of good quality and filter is well distributed in e effective area ensure fully mix of air. water and bio-membrane. Bio-membrane gains greater surface area during operation with activity and pore variability which is unparallel by other domestic fillings.
Compared with hard cellular packing. this fillings has bigger pore variability: compared with soft packing. it boasts long lifetime and non-adhesive connecting groups: compared with semi-soft packing. it enjoys bigger surface area. rapid film and low cost. thus it is the new choice after those previous fittings.
