Abstract
A recirculating aquaculture system (RAS) is disclosed, which includes a main tank, in which fish or shellfish are farmed; a first reactor fluidically connected to the main tank, wherein the first reactor is a batch reactor that operates under anoxic conditions; a second reactor fluidically connected to the main tank, wherein the second reactor is a moving bed biofilm reactor (MBBR); a feed stream fluidically connected to the main tank; and a data-driven controller operably connected to the first reactor, the second reactor, and the feed stream, wherein the data-driven controller is configured to bring and maintain the system (RAS) at a desired state.
Claims15
A recirculating aquaculture system (RAS) comprising:
- a main tank;
- a first reactor fluidically connected to the main tank, wherein the first reactor is a batch reactor that operates under anoxic conditions;
- a second reactor fluidically connected to the main tank, wherein the second reactor is a moving bed biofilm reactor (MBBR);
- a feed stream fluidically connected to the main tank;
- and
- a data-driven controller operably connected to the first reactor, the second reactor, and the feed stream, wherein the data-driven controller is configured to bring and maintain the system at a desired state,
- wherein the first reactor comprises a first motor controller connected to the data-driven controller to control the outlet stream from the main tank and to control the inlet stream to the first reactor, and wherein the second reactor comprises a second motor controller connected to the data-driven controller to control the outlet stream from the main tank and to control the inlet stream to the second reactor.
A method of operating a recirculating aquaculture system (RAS) comprising:
- farming fish or shellfish in a main tank, which has a feed stream fluidically connected thereto;
- operating a first reactor under anoxic conditions, the first reactor being fluidically connected to the main tank;
- operating a second reactor, which is a moving bed biofilm reactor (MBBR) fluidically connected to the main tank;
- operating a data-driven controller connected to the first reactor, the second reactor, and the feed stream, to bring and maintain the system at a desired state;
- controlling, via a first motor controller connected to the data-driven controller, the outlet stream from the main tank and the inlet stream to the first reactor;
- and
- controlling, via a second motor controller connected to the data-driven controller, the outlet stream from the main tank and the inlet stream to the second reactor.
A recirculating aquaculture system (RAS) comprising:
- a main tank;
- a first reactor fluidically connected to the main tank, wherein the first reactor is a batch reactor that operates under anoxic conditions;
- a second reactor fluidically connected to the main tank, wherein the second reactor is a moving bed biofilm reactor (MBBR);
- a feed stream fluidically connected to the main tank;
- a plurality of sensors in the main tank, the first reactor, and/or the second reactor configured to measure two or more of pH, oxygen reduction potential (ORP), dissolved oxygen (DO), temperature, feed concentration, mass+protein content, oxygen uptake rate (OUR), ammonia, nitrite, nitrate, phosphate, COD levels, levels of biofloc in the first reactor, levels of biofilm in the second reactor, and/or feed input;
- and
- a data-driven controller operably connected to the first reactor, the second reactor, the feed stream, and the plurality of sensors,
- wherein the data-driven controller is configured to bring and maintain the RAS at a desired state by using a model of the RAS and data-driven iterative optimization using machine learning,
- wherein the data-driven controller is configured to control, via a first motor controller connected to the data-driven controller, the outlet stream from the main tank and the inlet stream to the first reactor, and
- wherein the data-driven controller is configured to control via a second motor controller connected to the data-driven controller, the outlet stream from the main tank and the inlet stream to the second reactor.
