Made by advanced technology, the glossy sand filter series appeared quiet smooth and bright, the surface has UV-proof function, which can also withstand acid, alkalis and high temperature. As a new produced environment-friendly product, it's really the first choice for any swimming pools.
So far, most of the swimming pool uses traditional sand filter, it filled by quartz inside as the filter media to prevent water suspended substance and impurity into the pool. Given that traditional sand filters cleaning itself by reversing the flow and use backwash to flush dirty from valve, but it can not completely discharge the dirty on the bottom. In fact it did harms to the water quality and affect human health.So it's more completely purifying the swimming pool water.
