Abstract:
1. A method of determining and displaying the state of wastewater being treated in a batch reactor having a cycle time, the state of the wastewater determined using ORP measurements and a PC including a display comprising the steps of: a) measuring the ORP value of the liquid over a reactor cycle using an ORP probe in the reactor using the PC; b) plotting the ORP value of the reactor contents over time to create an ORP curve; c) calculating the value of the slope of the ORP curve at a first period in time using the PC; d) calculating the value of the ORP curve at a second period in time using the PC; e) calculating the changes in value of slope of the ORP curve from the second period in time to the first period in time using the PC; f) comparing using the PC the slope of the ORP curve at the first period in time with the slope of the curve at the second period in time with the change in value of the slope of the ORP curve between the first and second period of time and with the ORP value at the end of the second period in time to determine the status of the wastewater in the reactor; g) shading the plot of the ORP curve to reflect the state of the wastewater in the reactor based upon the determination of analyzed data; and, h) selectively displaying the plot of the ORP curve and the shading of the ORP curve on the display to provide an illustration of the state of the reactor usable by the operator to control the treatment of wastewater.
