1. Pool Filter Ball: Pool filter fiber ball is a threedimensional structure of the filter medium made by polymer through a special process. It has a large specific surface area and porosity, which can effectively remove impurities such as suspended solids, colloids, and bacteria in water. 2. Filtration Performance: The pool filter ball is made of polyester fiber material, which makes it have high filtration efficiency. Fiber balls are more effective at retaining fine particles than traditional sand filters, resulting in a higher standard of water purification, and a 3.1 lb filter is equivalent to 100 pounds of sand, which is lighter and more effective than traditional sand filters. 3. Reusability: After using the pool filter fiber ball for a period of time, its filtration performance can be restored by backwashing, so as to achieve multiple reuses. This not only reduces the operating costs of users, but also reduces the generation of waste, which is conducive to environmental protection. 4. Versatile: Swimming pool filter balls are suitable for swimming pools, aquariums, fish tanks, gardens, etc. It is also suitable for industrial wastewater treatment, deep purification of drinking water, aquaculture water purification and other fields. Its versatility makes fiber balls one of the most important materials for the water treatment industry in the future.
