摘要： By reducing the amount of monitoring water required to measure and monitor the quality of ultrapure water with a plurality of measuring instruments, the size of an ultrapure water production system is reduced, whereby the system cost is reduced. When a portion of ultrapure water supplied from the ultrapure water production system to a use point is separated to monitor the water quality, the water is allowed to pass through a monitoring system consisting of two or more stages of different types of water quality measuring devices connected in series so that the water quality is monitored. Because the ultrapure water extracted from a supply pipe extending from the ultrapure water production system to the use point is allowed to pass, in series, through two or more stages of different types of water quality measuring devices connected in series, by making these measuring instruments use the same monitoring water, which is required for measuring the water quality, the amount of monitoring water can be reduced. As a result, the size of the ultrapure water production system can be reduced, and hence, the system cost can be reduced.

摘要： A method of biologically treating water and more particularly, a process for nitrifying and denitrifying water includes employing a continuous aeration mode and a sequential aeration mode. In the continuous aeration mode, nitrification and denitrification reactions occur simultaneously in the water. The continuous aeration mode occurs when the nitrate concentration of the water reaches a predetermined low threshold. The sequential aeration mode occurs when the nitrate concentration reaches a predetermined high threshold. When in the sequential aeration mode, aeration is ceased when the ammoniac concentration reaches a predetermined low threshold and aeration is activated when the ammoniac concentration reaches a predetermined high threshold.
