INTERFILT® SK Gravity Filter (not available in all locations)

The SK Gravity Filter INTERFILT® is an open sand filtration generator with differential-pressure-controlled backwashing and integrated backwashing water storage tank. With this filter generator water can be treated economically.

Advantages

  • No energy consumption (e.g. electricty, compressed air, etc.)
  • No consumable material
  • No moving parts and thus no wear
  • No maintenance expenses

Application Areas

The Gravity Filter is suitable for almost all filtration tasks, such as:

  • Partial flow cooling water filtration
  • River, Industrial and Drinking Water Treatment
  • Iron removal from well water
  • Waste water purification to reduce suspended solids, COD - BOD5 and phosphate content (4th purification stage) etc.

Features

  • No control equipement: The filter uses no moving parts as valves, flow meters, controllers or display devices
  • No Pump: The volume of water required for back washing is held in teh storage area inside the filter, which means ther is no need for a back washing pump
  • No compressed air, pressurised water or electrical power: All processes are controlled and driven by the filter itself
  • No operating personnel: The filter works fully automatically and required no external intervention
  • No wear parts: No moving parts and thus no wear.
