1.Special design of surface,stronger bio-film growth capacity;
2.Large specific surface area,high voidage,the more periphyton biomass;
3.Unique design of structure and shape according to hydro mechanics,strong
three-dimensional flow dynamics in the water; 4.Adding hydro philic groups and other trace elements,the bio film formation time only 3-15 days;

5.Excellent impact strength,strong gas shear capacity;
6.Without any holder,easy to cure,save energy and space.
