Gravity Filters

Task: Filtration. Method: Gravity.

Whether for cooling water filtration, the treatment of river, operating or potable water or the removal of iron from well water, ProMinent gravity filtration systems are suitable for nearly all filtration tasks. Best of all, they require no energy, wear parts or consumables. It doesn't get more cost-effective than that!

Say goodbye to pollutants!

In nature, water is part of a continuous cycle. Soft rainwater penetrates the surface and comes into contact with rock and natural and synthetic materials. As a result, various suspended and dissolved particles, organic and inorganic compounds end up in the water. These pollutants can cause damage when the water is used, so they must be removed. ProMinent’s water softening systems and water filters provide the solution to this very problem.

Example: Sand filtration

The gravity filter INTERFILT® SK is an open sand filter system with differential pressure-controlled backwashing and integrated backwashing water tank. This filter system is an extremely economical method of water treatment. Again, the advantages are obvious: zero energy consumption (electricity, compressed air etc.), no consumables, no wear parts and no maintenance costs. Our filtration specialists are here to help.

Your benefits

  • No controls: The filter needs no moving parts, like valves, flow meter, controller or display equipment, for filtering/backwashing and post-rinsing
  • No pumps: The required volume of backwashing water is stored in the storage tank below the filter, making a back-flushing pump redundant.
  • No compressed air, pressurised water and electrical energy: The filter controls and performs all processes independently
  • No operating personnel: The filter works fully automatically, without external intervention
  • No wearing parts: No moving parts – no wear and tear.
