---the special spontaneous suitable filter material invented by Professor Li Zhenyu in Department of Enviroment , Tsinghua University
---the design created by Dean and Tsinghua
Outstanding characteristics
I. Wide application range : widely used in separating impurity during the water treatment process, such as recycling cooling water treatment~{#;~}tap-water manufacturing~{#;~} the recovery of swimming pool water and public bathhouse~{#;~} and the water used in scenery, and aquatic product cultivation , domestic ordinary and industrial wastewater~{#;~} pretreatment of seawater desalting and membrane separation technology
II. High filter efficiency : the efficiency is about 80~98%; input water SS< 50~200mg/L, output water SS< 1~10mg/L
III. High filter speed : about 40~150m/h
IV. High backwash efficiency . The rate of used water during backwash is less than 0.5~1.5% and the rate of the remaining mud is lower than 0.5~1.0%
V. Economizing occupied area. It is 1/10~1/5 of the silicon sand filter which treats the same water quantity
VI. High reliability . It is designed and made according to the standard
VII. Long service life : 15~20 years.
