FRP water treatment tanks are manufactured from high quality composite materials.They are widely used for residential,commercial,industrial water,including the electroplating wastewater treatment industry,industrial boilers,chemical industry,light industry,textile,and many other fields.The liner is blow-moulded or rotationally moulded from HDPE or LLDPE material.The tank shell is made of FRP and high-performance epoxy resin,which greatly increases the pressure-bearing strength of the tank.The water treatment resin tank can be used as a filter or water softener. When used as a filter, the inside is filled with quartz sand or activated carbon to remove impurities in the water; when used as a water softener, the inside is filled with ion exchange resin to remove calcium, magnesium and other hardness ions from the water.
