Quartz sand filter is used in the first filter of the water treatment, the filter media is quartz sand, it can remove the suspended solids larger than the filter pores, nice corrosion resistancestrong absorption both can be used repeatedly. The quartz sand is divided into three layer: A coarse sand, medium sand, fine sand, with the filtering, the impurities remain more ,the porous filter is getting smallersmaller, so that fine particlesmicro-organisms were also down interception
