General Introduction: The HQ-DE Diatomaceous Earth (DE) filter is currently the ideal equipment for swimming pool filtration. Fine diatomaceous earth forms a filtration membrane on the surface of the filter screen, providing high filtration precision, stable performance, and simple operation. When the accumulated dirt adsorbed by the diatomaceous earth affects the filtration performance, a backwash is performed. The diatomaceous earth enters the water pump through a DE adding bucket and then forms the filtration membrane inside the filter. Water filtered by the DE filter is exceptionally clean, clear, and transparent.
Equipment Features:
  • Optimal Filtration: The DE filter currently provides the best filtration effect among all swimming pool filters.
  • Extended Operation: The filter can operate normally for up to two weeks before requiring maintenance.
  • Large Filtration Area: Large-capacity filter rods significantly increase the total filtration area of the unit.
  • Optimized Design: The unique internal filter rod design optimizes both the filtration and backwash effects.
  • Maintenance Requirement: Filter rods must be disassembled and cleaned once every quarter.
  • High Precision: Offers high filtration precision, capable of removing microorganisms as small as 1~2μm.
  • Superior Water Quality: The turbidity of the effluent after filtration is close to 0.1 NTU.
