Systems and methods for treatment processes

Abstract

Systems and methods for aeration and mixing processes are disclosed.

We claim: 
     
         1 . A wastewater treatment system for mixing wastewater in a containment unit, the system comprising:
 a source of pressurized gas,   one or more supply headers in connection with the source of pressurized gas,   one or more mixing nozzles on each of the supply headers, wherein each nozzle is connected to a supply header and each nozzle is configured with at least one release opening for introducing a burst of gas to mix the wastewater,   a pressure sensor that measures pressure in one or more of the one or more supply headers based on the pressure of content in the containment unit, and   a controller configured to adjust mixing of wastewater as a function of the level of wastewater in the containment unit based on the pressure measurement by the pressure sensor.   
     
     
         2 . The system of  claim 1  wherein the controller is configured to start and terminate a supply of pressurized gas to the one or more mixing nozzles for mixing the wastewater based upon the determined tank level. 
     
     
         3 . The system of  claim 2  wherein the system is configured to adjust the supply of pressurized gas to one or more supply headers based upon the determined tank level. 
     
     
         4 . The system of  claim 3  wherein the system is configured to adjust the supply of pressurized gas to one or more supply headers to maintain substantially consistent mixing of the wastewater despite fluctuations in the determined tank level. 
     
     
         5 . The system of  claim 1  wherein the controller is configured to generate an alert in response to the pressure sensor indicating a pressure measurement indicative of a fault. 
     
     
         6 . The system of  claim 1  wherein the controller is configured to initiate an automatic correction in response to the pressure sensor indicating a pressure measurement indicative of a fault. 
     
     
         7 . The system of  claim 6  wherein the automatic correction comprises a maintenance purge.
