About the laboratory

The Water Reclamation Engineering Laboratory (WREL) focuses on membrane technology for water/wastewater treatment. Membrane technology has various advantages over conventional treatment methods. However, due to several disadvantages such as high energy consumption, it has not become the mainstream technology in the field of water and wastewater treatment yet. Our mission is to remove such obstacles for widespread use of membrane technology. Membrane technology has huge potential to enhance sustainability in cities. Current research topics include the (1) identification of agents causing membrane fouling; (2) development of efficient membrane cleaning method; (3) development of energy saving membrane bioreactor (MBR) process; (4) recovery of resources from municipal wastewater by using membranes; and (5) application of forward osmosis (FO) to recover nutrients from dairy waste.

Professor Kimura made an on-line presentation entitled “Wise Water Use in Future Cities: Membrane Technology will Save the World” in GiFT 2013.
