Abstract
Systems and methods for enabling dynamic volumetric transitioning and segmentation of treatment conditions are disclosed. Such treatment conditions may include, by way of example, systems and methods for dynamically transitioning treatment environments within a reactor for activated sludge treatment processes. Such environments may include anaerobic, anoxic, fermentation, suboxic, and aerobic environments.
Claims18
A system for a treatment process of wastewater comprising:
- a reactor unit having a volume, a plurality of sub-volumes within the reactor unit having at least one of (i) one or more mixing devices, or (ii) one or more of aerators, wherein at least one of the plurality of sub-volumes constitutes a flexible environment configured to dynamically transition some or all of that sub-volume between two or more of anaerobic, anoxic, fermentation, suboxic, and aerobic environments, and wherein the flexible environment is not bounded by any physical barriers and comprises (i) the one or more mixing devices and (ii) the one or more aerators, wherein the one or more of the plurality of mixing devices and the one or more aerators in the flexible environment are arranged in an overlapping proximity to permit providing coinciding mixing and aeration, respectively, to the wastewater within the flexible environment;
- and one or more controllers for controlling the one or more mixing devices and the one or more aerators, wherein the one or more controllers selectively and independently controlling the one or more mixing devices within the flexible environment and selectively and independently controlling the one or more aerators within the flexible environment.
A control system for wastewater treatment systems comprising a plurality of environments within a reactor having a volume of wastewater the system comprising:
- a controller configured to independently and selectively control a first set of mixing devices positioned within a flexible environment of wastewater and to independently and selectively control a first set of aerators positioned in overlapping proximity to permit providing coinciding mixing and aeration, respectively, with the first set of mixing devices within the flexible environment so as to provide a first environment within at least a portion of the flexible environment wherein the first environment is a fermentation, suboxic, aerobic, anoxic, or anaerobic environment, wherein the controller is further configured to independently and selectively control the first set of mixing devices and to independently and selectively control the first set of aerators so as to dynamically transition at least a portion of the flexible environment from the first environment to a distinct second environment, wherein the distinct second environment is a fermentation, suboxic, aerobic, anoxic, or anaerobic environment, wherein the flexible environment is not bounded by any physical barriers, and wherein the controller is further configured to control one or more additional sets of mixing devices or one or more additional sets of aerators positioned within one or more additional sub-volumes of wastewater, wherein the controller is configured to control such additional sets of mixing devices and additional sets of aerators separately from the first set of mixing devices and the first set of aerators to provide one or more fermentation, suboxic, aerobic, anoxic, or anaerobic environments within the one or more additional sub-volumes.
A method for treating wastewater within a reactor unit containing a volume of the wastewater wherein the reactor unit includes a first set of a plurality of mixing devices and a first set of a plurality of aerators, the method comprising:
- independently and selectively controlling a first set of the plurality mixing devices positioned within a first sub-volume of wastewater in the reactor unit, independently and selectively controlling a first set of the plurality of aerators positioned in overlapping proximity with the first set of the plurality of mixing devices within the first sub-volume of wastewater constituting a flexible environment in the reactor unit to permit providing coinciding mixing and aeration, respectively, to the wastewater within the flexible environment, wherein the independent and selective control of the first set of the plurality mixing devices and the independent and selective control of the first set of the plurality of aerators disposed within the flexible environment is independent of any control of the first set of the plurality of mixing devices and the first set of the plurality of aerators positioned within other sub-volumes of the reactor unit, wherein one or more of the first set of the plurality of mixing devices and the first set of the plurality of aerators are selectively and independently controlled to provide a dynamic transition of an environment of the flexible environment from a fermentation, suboxic, aerobic, anoxic, or anaerobic environments to a distinct environment selected from one the group consisting of a fermentation, suboxic, aerobic, anoxic, and anaerobic environments, and wherein the flexible environment is not bounded by any physical barriers.
