本文介绍了高速溶解气浮（DAF）处理技术，包括短絮凝时间、高DAF水力负荷率和高过滤率。它总结了1997-1998年在弗吉尼亚州纽波特纽斯和康涅狄格州费尔菲尔德进行的试点研究。研究的目的是:确认使用6-7分钟的极短絮凝时间；研究17-44 m/hr（7-18 gpm/sf）的DAF水力加载速率；研究各种过滤器设计，包括10米/小时和20米/小时（4和8加仑/平方英尺）。该研究检查了DAF澄清水和过滤水的质量以及过滤水的产量。 DAF罐是在足够高的液压负载下进行测试的，以使气泡在没有预防措施的情况下离开罐。还研究了气泡携带的缓解。该研究的一个重要方面是检验从絮凝到DAF澄清和过滤的高速处理的整合。

This paper addresses high rate dissolved air flotation (DAF) treatment technology including short flocculation times, high DAF hydraulic loading rates, and high filter rates. It summarizes research carried out at the pilot scale in 1997-98 at Newport News, Virginia, and at Fairfield, Connecticut. The objectives of the research were: to confirm the use of very short flocculation times of 6-7 minutes; to investigate DAF hydraulic loading rates of 17-44 m/hr (7-18 gpm/sf); and, to investigate various filter designs including rates of 10 and 20 m/hr (4 and 8 gpm/sf). The study examined the quality of DAF clarified water and filtered water as well as filtered water production. The DAF tank was intentionally tested at hydraulic loadings high enough to cause air bubbles to leave the tank without preventive measures. Mitigation of air bubble carryover was also investigated. An important aspect of the research was examination of the integration of high rate treatment from flocculation through DAF clarification and filtration.
