Dynamox

Delivering Oxygen: where you want it, when you want it

The simplest way to deliver oxygen using DynamOx is to turn it on and let 'er rip. Because the oxygen requirement is rarely known precisely, this means of operation invariably delivers less oxygen than is required (and thereby limits the pollutant degradation) or delivers excess oxygen (which is therefore wasted). In other well defined applications (such as groundwater applications), the DynamOx can be operated in a timed mode. This allow the DynamOx unit to deliver oxygen for a set period of time (say 15 minutes) followed by a shut down period (say 45 minutes). The variations of the timing sequence are virtually endless. Thus the delivery periods can vary throughout the day, throughout the week, through the month, throughout the year. The advantage of using the timed option is that the cost of a dissolved oxygen probe can be avoided. The disadvantage of precluding a DO probe is that the operator has little knowledge of the oxygen consumption rate - typically the most important variable in monitoring the biological process.
