摘要： A method of automatically ensuring against chloramine contamination in purified product water includes supplying input water to the system and purifying the water to generate the purified product water. The purifying includes removing chlorine and chloramine contamination from the water using a carbon filter and supplying chlorine-depleted water to a deionization filter, and deionizing the chlorine-depleted water using said deionization filter. The product water is supplied to a sensor for continuous monitoring of the resistivity of the purified product water by the first sensor, and an alarm is generated indicating possible chloramine breakthrough when the resistivity of the product water falls below a predetermined resistivity level, which is selected to provide a reserve filter capacity before breakthrough would occur. The carbon filter is replaced at least responsively to the alarm to ensure excess capacity of said carbon filter sufficient to prevent chloramine breakthrough in said product water.

摘要： A method and system of providing ultrapure water for semiconductor fabrication operations is provided. The water is treated by utilizing a free radical scavenging system. The free radical scavenging system can utilize actinic radiation with a free radical precursor compound, such as ammonium persulfate. The ultrapure water may be further treated by utilizing ion exchange media and degasification apparatus. A control system can be utilized to regulate a continuously variable intensity of the actinic radiation.
