| 7 | Foreword I. Introduction. I.A. Background. Oxygen (O2) is commonly used as a feed gas for generating ozone (O3) gas, which is subsequently used for disinfection or oxidation of water supplies. Oxygen may be generated onsite as a gas or liquid or purchased in bulk as liquid oxygen |
| 8 | I.B. History. The first edition of ANSI/AWWA B304 was approved June 12, 2005. Subsequent editions were approved by the AWWA Board of Directors on June 8, 2008, and June 9, 2013. This edition was approved on Oct. 24, 2018. I.C. Purpose of Standard. Because of the varied nature of oxygen production and feed equipment in use in the water industry today, it was the consensus of the AWWA Standards Committee on Oxygen that this standard should address only the recommendations fo I.D. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct |
| 9 | II. Special Issues. II.A. Storage and Handling Precautions. The storage and handling of LOX is widespread in many industries besides the water industry. Because of this, there are many codes and design standards associated with the storage and handling of LOX. Some of these |
| 11 | II.B. Gas Pretreatment. LOX must first be vaporized to a gaseous form prior to use for ozone generation. The vaporization step can be accomplished through the heating of LOX by ambient temperature air, ambient temperature water, or electrical energy. Once III. Use of This Standard.
