GSF FILTER

GSF filtration technology uses a bundle of fine flexible synthetic fiber. By using power of motor it twists the bundle of synthetic fiber to shrink pores, and water passes through the fiber. When GSF filter reaches setting pressure level, it releases the bundle of fiber and backwashes the fiber with pressurized air and water. That is why it doesn't allow loss of media and washes attached suspended solid on the synthetic fiber. Furthermore the vertical structure of filtration equipment maximizes the contact area than conventional filtration equipment.

Benefit

  • effective in removal of suspended solid, and effluent is qualified.
  • Size of this equipment is relatively small, light and economical.
  • Required time and required water quantity for backwash is also less.
  • This filter has longer lifespan and maintenance is easier.
  • Automatic Control system
  • Permeability of tjis equipment is effective and contact area is large.
  • Variety Usage for this filtration
  • Effective backwash due to its pliability of fine yarn bundle.
