Lamarre, B L

A system is described for removing hazardous contaminants from water comprising: a tray oriented substantially parallel to the horizon having an intake portion and an output portion, a system for providing water confining side walls about the periphery of the tray, an inlet adapted to distribute water to the intake portion. The tray includes baffles normal to the tray with the baffles and the side walls defining a single curved fluid flow path for frothing water across the tray. The flow path extends from the intake portion to the output portion and has a constant width throughout the length. The baffles and the side walls fit vertically above the tray. The tray includes an air diffusing element having a plurality of holes through it which are adapted to distribute air along the curved flow path from the intake portion to the output portion. A system for providing air to the air diffusing element is included, having the vertical height of the baffles and the side walls sufficient to maintain deep frothing water throughout and within the flow path without back mix or cross mix of froth.
