Swimming pool filtration equipment have?

Pool filtration equipment is divided into: sand filtration tank, buried loop filter, wall-mounted loop filter
1, Shagang filter principle: generally placed a certain amount of quartz sand, in a range of different size specifications of quartz sand, sand tank, quartz sand from top to bottom, from small to large and so arranged normal filtration, water from the sand into the upper from lower it. When the time between the water flows through the filter layer from the water portion of the solid was suspended material into the upper layer filter tiny empty eye formed by adsorption and mechanical retention effect is trapped by the surface layer of filter material, while the suspended solids are retained they overlap and bridging role, which is called the filter surface layer of the thin film filters. Such filtration not only the surface of the filter layer, and when the water enters the intermediate filter layer have this interception, as distinguished from the filter surface layer, this effect is called osmotic filtration.
2, buried loop filter principle: buried filtration system is a pumping station, filtration, dosing and disinfection in one of the more intelligent filtration system, changed the traditional sand filtration tank. More than the national standard for public swimming pools in Australia, is a large public swimming pool designed for more than 500 cubic meters, the game of pool solar cover rollers filtration system.
3, wall-mounted and embedded principles and buried the same, but different installation methods.
