With continuous changes in urban and industrial wastewater quality and quantity, and increasingly stringent environmental regulations for water treatment, available land resources are becoming more limited. This requires wastewater treatment systems to have high operational flexibility while maximizing land-saving efficiency.
The UNITANK process is an advanced wastewater treatment technology developed to meet these requirements. It integrates the advantages of the SBR (Sequencing Batch Reactor), conventional activated sludge process, and the three-channel oxidation ditch. With an integrated design, it not only features the characteristics of SBR systems but can also operate continuously at a constant water level like conventional activated sludge processes. Its operating mode is similar to a three-channel oxidation ditch, enabling continuous influent and effluent treatment.
The UNITANK process offers several distinctive advantages:
The Staggered Tube Settlers sedimentation device used in UNITANK systems features a small hydraulic diameter and a large wetted perimeter, providing optimal hydraulic conditions for sedimentation. It accelerates the solid-liquid separation process in the sedimentation tank and shortens the hydraulic retention time, thereby significantly reducing the footprint of the alternating biological sedimentation tank and lowering overall construction investment.
The Staggered Tube Settlers sedimentation method applied in UNITANK systems is characterized by a compact footprint, high efficiency, and convenient operation and management.
