AERATION APPARATUS Model FM 106
AERATION APPARATUS Model FM 106
Sci-tech Aeration Apparatus Model FM 106 comprises an open tank equipped with a propeller stirrer. Air is supplied via a compressed air line through a pressure regulator valve, and through a flow meter to a diffuser positioned within the tank. A variety of diffusers are included. The dissolved oxygen content of the water in the tank is measured by means of a dissolved oxygen probe, which includes direct reading of water temperature.
Mounted on the base is the clear 27-litre acrylic water tank. On the front of the tank is a depth scale and at the base a drainage tap. The digital stirrer control includes speed and torque measurements. This is supported by a metal bar. Three diffusers – sparger tube, treble airstone and single airstone – may be separately attached to the aerator tube.
Variable-speed adjustment of the stirrer paddle provides different levels of turbulence in the tank.

Item Description
The purpose of the Sci-tech Aeration Apparatus Model FM 106 is to permit study of the oxygen transfer characteristics of diffused air systems and the physical and chemical parameters that influence their oxygenation capacity. These studies are a necessary prelude to the understanding of the biological treatment of waste waters.
