Latest Patents
Miyazawa's latest patents include an ultrapure water production system and an ultrapure water production method. The ultrapure water production system is designed to produce ultrapure water and consists of several key components. These include a pre-treatment unit, a primary pure water production unit, a secondary pure water production unit, and a storage unit that can store raw or treatable water. Additionally, it features a recovery treatment unit that removes impurities from used ultrapure water, allowing for the recycling of water back into the system.
The ultrapure water production method involves a sophisticated process for producing pure water. This method efficiently adds agents to water supplied to a reverse osmosis membrane. It includes steps such as obtaining first treated water by adding polyaluminum chloride to raw water containing free chlorine, followed by obtaining second treated water through the addition of a reducing agent containing sodium disulfite. The final step involves treating the second treated water with a reverse osmosis membrane.
