ITT (now Xylem) Water & Wastewater Leopold Business Unit has provided dissolved air flotation (DAF) systems to the municipal potable water treatment market since early 1990s. This chapter discusses DAF process and high-rate Clari-DAF® system design criteria. It also presents data from pilot studies case of full-scale plants in operation showing expected performance through system.

Early fishing seems to have been mainly hunting and gathering along shores and inlets with fish farming emerging somewhat later in time. Capture fisheries expanded rapidly in the 19 and 20 centuries AD reaching the peak annual production of over 90 million metric tonnes in the early 1990s. Since ...

We used pulsed-field gel electrophoresis analysis and genotyping to compare clinical isolates of Bordetella pertussis recovered since the early 1990s in Finland and France, 2 countries with similar histories of long-term mass vaccination with whole-cell pertussis vaccines.

A large number of analog chaos-based secure communication systems have been proposed since the early 1990s exploiting the technique of chaos synchronization. A brief survey of these chaos-based cryptosystems and of related cryptanalytic results is given. Some recently proposed countermeasures against known attacks are also introduced.
