Research Unit on Water and Wastewater Treatment Technology



As a decrease in quality and quantity of water resources, innovative water quality control technologies is now needed in the world. We have suggested a new water management system which was based on the membrane technology. To achieve it, the following three topics are now studied. (1) Membrane bio-reactor (MBR) is a promising technology for the water reuse field and we modified it to achieve half of their energy cost. In addition, we developed to recover the phosphorous from MBR sludge with the use of special adsorbent. (2) The major causes of membrane fouling is gbiopolymerh, protein and polysaccharides, and we developed the method to eliminate them in advance of membrane filtration. (3) Landfill leached contained a high concentration of boron and we eliminated it with the use of modified used-RO membrane.
