escription du produit FilterBalls are lightweight, high-performance filtration media. high efficiency, designed to replace sand in private swimming pools and industrial or commercial filtration systems. No more hassle or mess, a single cubic foot bag of FilterBalls replaces and exceeds 100 pounds of sand. Most household filters require less than 2.5 kg of FilterBalls Much lighter than the sand you are usingSave a lot of money on your electricity billWhat are filter balls and why are they better than other filtration media?With 100% POLYETHYLENE, it is a breakthrough in swimming pool filtration. In hindsight, FilterBalls are so much easier to use. handle only large sandbags. They were certainly millions of times easier to make. remove from the pool filter that the old viscous sand from which you had drawn for exactly over an hour. It can also capture smaller particles than normal filtration sand. 100% POLYTHYLNEMuch easier to use. manipulateThe filter pump is significantly quieterCan capture smaller particles than normal filtration sand Super facile grer Filter balls are supposed to be super easy to clean. handle, 100 times lighter than sand filter masses and improve circulation and filtration, with lower filtration pressure and higher flow rate. Eliminate pulling and disposing of hundreds of pounds of sand. How it works The large number of biological groups linked to its strong specific surface area. Microsuspensions, which do not precipitate easily, can be processed by direct trapping and electrochemical adsorption onto oil and other contaminants. Recyclable FilterBalls are recyclable and can extend the life of your other equipment (less operation), saving energy. More complete backwashing for longer filtration cycles. And lower system pressure than sand.
