The filter ball is made of polyester fibers tied together. Compared with the traditional steel filter material, it has good elasticity, does not float on the water surface, and has a long working cycle. During the filtration process, the voids of the filter layer gradually become smaller along the direction of water flow, which conforms to the ideal distribution of the porosity of the filter material from the top to the bottom, so as to form a fast filtration rate, a large amount of dirt interception, and a good filtration effect, which can be used repeatedly, not all Replacement, saving time and effort.
Advantages of filter ball:
1. Large specific surface area: the attached biological group is relatively large
2. Strong adsorption capacity: better effect on degreasing and flocculation containing sewage
3. Good filtering effect: an ideal filter layer distribution state is formed during filtering
The use of filter balls in a sand filter is very simple, just fill the filter balls into the filter and run.
