Supplier shall provide LOX with the following chemical requirements (Sec 4.3 of ANSI/AWWA B304-18): LOX suitable for use in the generation of ozone for the treatment of potable water shall have an oxygen content of at least 99.0 percent by volume. Water/moisture content. The water/moisture content of the LOX shall not exceed a dew point of - 80°F (-62.2°C or 7.8 [v/v]) at the time of delivery. Total hydrocarbon content. The total hydrocarbon content (as methane) of the LOX shall not exceed 40 ppm (v/v) at the time of delivery. Particle size and content. The liquid oxygen should be filtered through a 10-µm nominal (40-µm absolute) filter located in the line to the shipping container. Other impurities. Other impurities include nitrogen, argon, and other inert gases. The sum of these impurities shall not be sufficient to prevent achieving the minimum oxygen content of 99.0 percent by volume...
