KRBio-SAC is a biologically advanced treatment process for sewage and wastewater facilities, and consists of an anaerobic tank, anoxic tank, Bio-SAC tank (aerobic tank) filled with waste tire carrier, reaction promotion tank, and a secondary sedimentation cell.
It utilizes both adherent-type microorganisms and suspended-type microorganisms of the carrier at the same time, and maximizes the fluidity of the carrier to enhance the treatment performance.
This technology improves carrier displacement, deposition, and loss, which are the drawbacks of the carrier system.

※ Refer to ETV No. 176
Guarantees excellent efficiency in the removal of organic matter and pollutants such as nitrogen and phosphorus by increasing opportunities for contact between organic matter and microorganisms through continuous flow of carriers in the Bio-SAC tank, and excellent responsiveness to load fluctuations
Guarantees stability by means of advanced treatment process verified through numerous application records
It is suitable for the improvement of advanced treatment systems in existing facilities by minimizing the site area, and offers high stability against shock loads and flow load fluctuations.
Provides design and operation optimized for on-site conditions based on experience accumulated over many years
Green technology to recycle waste tires, a waste resource
Reduces maintenance costs by using durable materials necessary for core technology to extend the lifespan of equipment
Since the structure is simple and compact, it is possible to carry out maintenance with a minimum number of personnel.
All facilities are easy to operate with the construction of the operation control system (MMI) and the application of a remote automatic control program (PLC).
