Abstract: Ultrapure water is water from which ionic components including minerals, particulates, and microorganisms have been removed to a certain level or less. In this sense, it is also expressed by the term de-ionized water. As ultrapure water is essential for high-tech industries such as semiconductors, displays, solar power, pharmaceuticals, bio, and fine chemicals, related technology must be improved to the world's best in order to supply high-quality ultrapure water. The ultrapure water manufacturing process mainly consists of three steps: pretreatment, pure water production, and water quality adjustment. In the pretreatment step, filtration and reverse osmosis are combined to mainly remove particulate matter and dissolved substances. However, it is not easy to remove urea to a level of 1 ppb through these processes. In this study, we aim to develop a technology to remove urea in ultrapure water using enzymes immobilized on magnetic microparticles.
