Gravel Filters



Epoxy Coated Steel Media Filter tanks offer two inbuilt chambers for eGravel Filters content_2fficient filtration and back flush uniformity. The top chamber contains the gravel media and is separated from the bottom chamber by a layer of conical mushrooms. The mushroom design provides thorough backflushing with equal pressure throughout the entire sand media bed whilst preventing the gravel media from entering the bottom chamber. These systems are available in tank sizes from 12” (300mm) to 48” (1200mm) for durable and dependable operation. Gravel Media Systems are designed to be modular to cater for most flow requirements.
Gravel Filters are used from primary filtration of water from reservoirs, dams, open canals, rivers, sewage water and other types of contaminated water.
  • Up to 8 bar working pressure applications
  • Primary filter for water from open reservoirs and recycled water
  • Filtration of water contaminated with algae and other organic materials
