HBC(Hanging Bio-Contactor) System
This technology ensures stable wastewater treatment performance and capacity as it traps high concentrations of attached microorganisms and airborne microbes in the aeration tank by using the stationary phase carrier method to complement the drawbacks of the existing activated sludge method, tricking filter method, and fluidized carrier method.

Process Chart


  • · Increase in treatment capacity thanks to the increase of microorganisms in the aeration tank
  • · Highly effective against low concentration wastewater or nitrification filter
  • · Low sludge generation
  • · Excellent treatment efficiency thanks to various microorganism species
  • · Low operating costs thanks to nitrification and denitrification occurring simultaneously
  • · Requires smaller workforce as MLSS and SL management is not required.
  • · No bulking and increase in settling tank performance
  • · Appropriate for intermittent operation

Characteristics Generates odor, attracts insect breeding (flies or mosquitoes), difficult to operate in winter Frequent mechanical failures Produces less microbial attachment as the air floats and contacts the media through aeration. Requires supplementing media. Requires more initial investment due to the installation of structures for fixing
