How to tell the quality of high-quality elastic filler, elastic filler is soft and semi-soft filler filler based on evolved, it combines the advantages of both. The structure is the plastic discs pressed into double ring buckle big plastic ring, the aldehyde fiber or polyester yarn pressure in the ring on the ring so that the fiber bundle evenly distributed; inner is plastic snowflake-shaped branches, both biofilm and can effectively cutting bubbles, increase oxygen transfer rate and utilization. The water vapor biofilm fully exchange, so that efficient processing of organic matter in water. Lu Feng elastic filament gap variability, it is not blocked, do not agglomerate, large surface area, low power consumption, long life, low cost. Elastic filler both flexibility and rigidity of the elastic yarn modest, arranged in a three-dimensional uniform radiation conditions, multi-level effective bubbles of oxygen cutting, gas, water, biofilm get full access to the exchange, citing a turbulent state, improved oxygen transfer rate and power efficiency of oxygen, promote microbial metabolism, strengthen the wastewater treatment efficiency. Gongyi City Water Treatment Lu Feng Packing Co., Ltd. is the domestic production of water treatment materials, environmental science and technology enterprise, engaged in water treatment materials research, production and application, has accumulated a wealth of drinking water treatment, industrial wastewater treatment valuable experience, technical force, excellent equipment, advanced technology, is a collection of scientific research, production, operating as one of the joint-stock enterprises.
