W10 MKII Aeration Unit

 

W10 MKII Aeration Unit

The purpose of the Armfield Aeration Unit 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.

Description

The Armfield Aeration Unit 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. 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.
