Guangzhou-Puda Sports Equipment Installation Co., Ltd. is a collection of swimming pool water treatment, sauna spa equipment, marketing landscape water treatment, equipment and engineering products, related accessories and services in one of the new high-tech enterprises. The company uses the most advanced water treatment technology sand tank pressure gauge, for the majority of a swimming pool, spa bath, landscape fountain pool, sauna, pool, and other projects to provide the most optimal configuration and high-quality equipment and related products. Sand filtration principle: sand tank is generally placed a certain size quartz sand, within a certain range of different size specifications of quartz sand, sand in the sand tank tank installation, quartz sand from top to bottom, from small to large and so arranged normal Side sand filtration tanks, water enters from the upper sand, from the lower it. When the time between the water that flows through the filter layer from the water portion of the solid suspended material into the upper filter formed by tiny empty eye adsorption and mechanical retention effect is trapped by the surface layer of filter media, while those trapped in suspended solids they overlap and bridging sand tank, as if the filter layer formed on the surface layer of the film, continue to filter the water, suspended matter, which is the so-called membrane filtration filter surface layer. Such filtration not only the surface of the filter layer, and when the water enters the intermediate filter layer also has this interception, the surface layer is different from the filter, this effect is called the osmotic filtration. In addition, due to the tightly arranged sand between each other, when suspended particles in the water flowing through the sand those crooked channel, there will be more opportunities and time collide and contacts the filter surface, so, suspended solids in the surface of the sand particles adhere to each other and the floc coagulation process and the contact occurred. In summary, Sand filtration is through a membrane filter, the filter penetration and contact filtration process to further purify the water.

The company uses the most advanced water treatment technology for the majority of a swimming pool, spa bath, landscape fountain pool, sauna, pool, and other projects to provide the most optimal configuration and high-quality equipment and related products. Sand filters of glass fiber wrapped production molding, resistance to deformation, corrosion and wear. When the water flows through the filter bed Sand, dirt and organic matter in the water trapped filter bed, the water is filtered. Filter bed trapped thing, the more clear sand filtered water tank, the higher the efficiency of the sand tank, all the procedures how to valve operation, regular recoil, sewage can be.
