SLURRY FEED SYSTEM AND METHOD

1 . A method of controlling odor in a wastewater stream comprising:

introducing a treating slurry for a predetermined treating period through a conduit to the wastewater stream;

introducing a flushing fluid to the conduit for a predetermined forward flushing period; and

introducing the flushing fluid to the conduit for a predetermined reverse flushing period.

2 . The method of claim 1 , wherein the predetermined forward flushing period is in a range of from about 60 seconds to about 180 seconds and the predetermined reverse flushing period is in a range of from about 20 seconds to about 120 seconds.

3 . The method of claim 1 , wherein the predetermined treating period is in a range of from about 30 minutes to about 120 minutes.

4 . The method of claim 1 , further comprising measuring one or more parameters of at least one of the wastewater stream, the treating slurry, and the source of the treating slurry.

5 . The method of claim 4 , wherein the measured parameter is selected from the group consisting of flowrate, pH, pressure, temperature, volume of the treating slurry, pump speed, and viscosity.

6 . The method of claim 5 , further comprising adjusting a flowrate of the treating slurry based at least in part on the measured parameter.

7 . The method of claim 1 , further comprising:

measuring a wastewater stream parameter and a treating slurry parameter;

identifying a control profile based at least in part on the wastewater stream parameter and the treating slurry parameter; and

regulating addition of the treating slurry into the wastewater stream based at least in part on the control profile.

8 . The method of claim 1 , further comprising generating an alarm condition when a magnitude of a difference between at least one expected value and at least one measured parameter of the system exceeds a predetermined tolerance value.

9 . A computer readable medium including computer readable signals stored thereon defining instructions that, as a result of being executed by a controller, instruct the controller to perform a method of wastewater odor control comprising:

generating at least one first control signal in a treating mode;

generating at least one second control signal in a flushing mode;

identifying a first triggering condition that initiates generation of the second control signal; and

identifying a second triggering condition that re-initiates generation of the first control signal.

10 . The computer readable medium of claim 9 , wherein identifying the first triggering condition comprises:

monitoring a duration of an elapsed treating time during which the first control signal is generated; and

comparing the duration of the elapsed treating time to a target treating period.

11 . The computer readable medium of claim 10 , wherein identifying the second triggering condition comprises:

monitoring a duration of an elapsed flushing time during which the second control signal is generated; and

comparing the duration of the elapsed flushing time to a target flushing period.

12 . The computer readable medium of claim 9 , wherein identifying the first triggering condition comprises:

measuring a flowrate of a treating slurry introduced into the wastewater; and

comparing the measured flowrate to an expected flowrate of the treating slurry to be introduced into the wastewater.

13 . A method of facilitating odor control of a wastewater stream comprising:

providing a controller configured to actuate a pump that is disposed to deliver a treating slurry to the wastewater stream through a conduit.

14 . The method of claim 13 , further comprising storing a predetermined treating period in the controller.

15 . The method of claim 13 , wherein the treating slurry comprises at least one of calcium hydroxide and magnesium hydroxide.
