1999年2月初，与洛杉矶水电局（LADWP）进行了臭氧接触器的多尺度对比研究。本研究的目的是在三个接触标度的不同臭氧氧化水平下探测溴酸盐的形成，并确定可比性。将两种不同的实验室规模接触器与中试规模接触器和全规模臭氧接触器进行了比较。作为与LADWP研究的比较，本文介绍并讨论了法国公用事业公司的类似研究结果。包括9个参考文献、表格、图表。

A multiple-scale comparison study of ozone contactors was conducted with theLos Angeles Department of Water and Power (LADWP) in early February, 1999. The purpose of the study was to probe bromate formation at different levels of ozonation at each of three contactor scales, and determine the comparability. Two different bench-scale contactors were compared with a pilot-scale contactor and a full-scale ozone contactor. As a comparison to the LADWP study, results of a similar study with a French utility are presented and discussed. Includes 9 references, tables, figures.
