How the composition filler composed of a fiber bundle, a plastic sheet, the sleeve, the center rope. The combination of fillers is developed on the basis of soft filler and semi-soft filler, it combines the advantages of both. Its structure plastic wafer pressure double ring buckle into a large plastic rings, the hydroformylation fiber or polyester yarn evenly distributed pressure in the ring on the ring, so that the fiber bundles; inner ring snowflake-shaped plastic branches, both linked to the film yet effective cutting bubble, oxygen transfer rate and utilization. Moisture biofilm fully exchange, the efficient processing of organic matter in the water. Purposes: for sewage, waste water treatment works, supporting in contact with the tower oxide, oxidation pond oxidation tank and other equipment, biological carrier for wastewater treatment is a biological contact oxidation and anaerobic fermentation. Performance characteristics: high thermal performance, small resistance, water distribution, gas distribution performance, easy long film, but also cutting bubble. Parameter specifications: unit diameter Φ150mm, spacing 80mm, 100mm two specifications. Centre rope plastic rope and fiber rope two. Ordering Information: Order expressly required the combined length of the filler, cubic number, spacing, and so on. Tel; 0371-64116159,13838264288 URL; the http; www.juluhualv.cn
