Using the calculated KLa (See Develop Kla) an "Oxygen-Transfer Capacity" curve can be created which will show the operator the pounds of oxygen that are available.

Using Oxygen -Transfer Capacity Curve

Based on the KLa previously saved, we can plot the pounds of oxygen available for one or more basins.  Later in this sequence we will also be able to predict oxygen needs based on load and mixed liquor concentrations.

BUTTONS:

	Selects highlighted Basin.
	Selects all basins.
	Un-selects highlighted basin.
	Un-selects all basins.
	Generates plot of oxygen transfer capacity vs. D.O. plot.
	Returns to the main menu.

Field Descriptions

Basin Temperature:  Enter desired temperature for the analysis. Default is 20 Deg. C.

Beta: Enter desired Beta.  Ratio of oxygen saturation of the wastewater to that of tap water.  Default is .95

 

EXAMPLES:

Based on system KLa and Basin volumes this graph shows how much oxygen can be transferred based on D.O. setpoint.
