- Integrated Fixed-Film Activated Sludge System



The Hydrok IFAS (Integrated Fixed-Film Activated Sludge) system has been developed utilising the Biotextil Cleartec media for which Hydrok are the appointed sole UK distributor.When used in conjunction with the Aquaconsult AEROSTRIP diffusers this system offers even further efficiencies within the treatment process. Biotextil Cleartec is a textile product made of 100% polypropylene which by the nature of its construction creates a large specific surface area on which biomass can grow.The construction of the material permits good oxygen supply and prevents excessive growth of thick layers of biomass thus maintaining the optimum efficiency of the process.The Biotextil Cleartec curtains are positioned directly above the diffusers, housed in a removable frame, set parallel to the flow. The configuration of the material allows for flexibility and movement within the flow of the tank, leading to an enhanced performance, this in turn increases the capacity of the waste water treatment plant.

  • Increased performance
  • Excellent nitrogen elimination
  • Reduction of surplus sludge
  • No blockages of the textile curtains
  • Reduced energy requirement
