Fiber ball filter material is a new material in filtration technology in recent years, which is a further development of past sand, ceramsite, foam filter material and other filter materials. Fiber ball filter materials made of chemical fiber filaments are different from traditional filter materials in that they are compressible soft filter materials with a large porosity accounting for %-% of the filter material layer. During the filtration process, the water flowing through the filter layer produces an assistant, causing the filter material layer to compress, and the gaps become smaller along the direction of the water flow, so the filtered water quality is good. The filtration rate can reach
Compared with sand filter material, it has the advantages of large retention capacity, high filtration rate, small water head loss, and long working cycle. Regeneration of the fiber ball filter material requires backwashing with air and water before repeated use. At present, fiber ball filter materials are under further development at home and abroad. The physical and chemical properties of the fiber ball filter material made of polyester fiber are as follows: the shape is spherical or flat ellipsoid fiber diameter - fiber length - filter ball diameter - density is. / filling density / porosity % specific surface area / filter material filtration rate reaches the actual mud interception volume /filter material. The amount of flushing water used for backwashing with soda water is %~% of the filtered water amount.
