Under the current environmental concerns and economic situation, the requirements for industrial wastewater treatment facilities have been diversified in addition to the prime objective of wastewater purification. We developed the modules of an Expanded Granular Sludge Bed (EGSB), Upflow Anaerobic Sludge Blanket(UASB), and ultra high rate sedimentation facility, all of which were our major systems for wastewater treatment. Then, the modules were commercialized as “BIOBED®-U”, “BIOTHANE®-U” and “SUMI-THICKENER®-U”, respectively. The modules have been well accepted by our customers and their sales are increasing, because of their technological differentiation, short delivery, and cost competitiveness. This paper introduces some of high-efficiency wastewater treatment facilities as well as the modules.
