Description
FIELD OF INVENTION

The current invention relates to the field of an artificial intelligence (AI), internet of things (IoT) based water body management system. The invention relates to aquaculture management by intelligent aeration, nutrient control, monitoring and maintaining water quality parameters at desired levels by modulating the function of aeration, nutrient control, and/or water recycling.


BACKGROUND

Deep confined water bodies generally have a depth of 5-45 m. In such confined water bodies, the seasonal variation due to daytime solar radiation forms three layers of temperature structure i.e. epilimnion, thermocline and hypolimnion. The thermocline acts as a barrier and doesn’t allow free passage of oxygen to the hypolimnion and exacerbates anoxic conditions. Compounds released from the sediment during anoxic condition dramatically affect water quality. Stratification leads to presence of lower density water at the top and higher density water stays at bottom further impede transmission of oxygen to the sediment from the atmosphere. Stratification periods tend to be longer during summers. This further inhibits consumption of oxygen by bacteria and other microorganisms at the sediment. Generally, bacteria utilize dissolved oxygen (DO) for the breakdown of biological matter such as dead phytoplankton, generating more phosphorous and nitrogen in an aquatic system. The abundant supply of phosphorous and nitrogen lead to growth of phytoplankton and eutrophication along with formation of hypoxic zones. Such anaerobic conditions lead to the formation of hypoxic zones, resulting in release of a range of toxic compounds from the sediment. Presence of feed and excreta of animals are significant factors that lower dissolved oxygen (DO) in the system. Absence of oxygen leads to enhancement of ammonia, nitrate, phosphate and also helps in growth of pathogenic bacteria at the sediment, leading to disease and mortality of aquatic animals. Among the toxic compounds from the sediment, ammonia has significant effect on water quality degradation and poses a risk to aquatic habitat particularly at an elevated pH. Further presence/entrapment of nitrogen in the form of ammonia and nitrate is also a key limiting factor for availability of nutrient. Moreover, unavailability of oxygen and reduction of redox potential at the sediment promote the release of Manganese (Mn), Iron (Fe), Phosphorus (P) via microbial and chemical reduction of metal oxides. Further, Phosphorous and Nitrogen (N) released from sediment diffuse to surface water and enhance the growth of phytoplankton. In addition, under anaerobic conditions sulfate-reducing bacteria become active leading to sulphide accumulation at the sediment. The resulting hydrogen sulfide is very toxic for aquatic life. Moreover, during very high redox conditions methyl-mercury is produced by methylation of dissolved inorganic mercury by anaerobic bacteria present in sediments. These nutrients accumulate with time and degrade the water quality of the waterbody. Furthermore, growth of N, P facilitates the growth of blue-green algae resulting in eutrophication. It is thus, imperative to provide adequate oxygen to the sediment so that the release of undesirable compounds can be reduced. Inducing a water current with velocity between 3-8 cm/s at the sediment-water interface helps in maintaining sufficient oxygen so that release of harmful compounds can be prohibited. Further the current enhances sediment oxygen demand (SOD) by four fold. Mainly under quiescent hydrodynamic and anaerobic conditions the sediment boundary layer becomes thick and oxygen infiltration to the sediment becomes restricted. The mixing at the sediment surface breaks the barrier as the sediment boundary layer between the sediment water interface which enhances oxygen uptake by the sediment. Moreover, sediment oxygen demand (SOD) uptake also depends on the morphometry of the waterbody.


Till now, various oxygenation systems have been deployed in water bodies. Among these oxygenation systems, hypolimnetic oxygenation systems fit the requirement and are most adopted as oxygenation of hypolimnion keeps bottom water cool, unlike destratification system which mixes water column and raises the temperature of hypolimnetic water which is deleterious for the aquatic life. Also, destratification systems which mix the water column of stratified water with higher capacity, are very costly. Further, oxygenation at the water surface is not effective as oxygenating at the hypolimnion. Thus, hypolimnetic oxygenation systems are used to oxygenate at the hypolimnion of the water bodies. Diffuser systems like Speece Cone, airlift, and bubble plume type systems are used to reduce oxygen demand at the water bodies. These systems are generally deployed and fixed at the bed of the waterbodies (> 10 m) . In general, these systems raise the oxygen concentration at the hypolimnion without disturbing the stratification. It has been observed that, by the use of these aeration systems the depletion of oxygen can be restored and anoxic condition can be prevented under certain environmental conditions. However, the installation cost and maintenance is very expensive for developing countries such as India. Furthermore, hypolimnetic oxygenation fails when the mixing at the sediment water interface is not performed. Instances have been reported that despite oxygenation, hypoxia could not be obliterated. In addition to it, due to spatially fixed nature of the system, the aeration could not produce sufficient mixing farther from the diffuser, as the bottom turbulence is also dependent on the bottom bathymetry and traps oxygen within a limited region. Furthermore, the dispersion of the oxygen from the farther region requires sufficient lateral velocity without being trapped near the oxygenation systems.


US7396456B2 provides a paddle wheel based aeration system suitable for ponds. It aerates by pumping the aquatic water into the air. It is suitable for epilimnetic aeration. However, SOD demand is neglected. KR100951787B1 describes a floating and manoeuvring device by a motor underwater impeller for generating an upward flow of water in the stagnant body of water, which also increases DO. This device generates vertical water column mixing by the rotational driving of the motor underwater impeller for generating an upward flow of water. US20140110323A1 provides a device to remove contaminants by aerating. It floats freely and aerates the upper strata of the waterbody. Navigation is by remote control, GPS or autonomous control. The propeller receives energy from conventional source. This device does not solve eutrophication issue,is not intended for hypolimnetic aeration, thus does not meet SOD. WO2020046523A1 describes a computerized feed system that is trained to determine amount of feed and feed type to dispense in a time horizon. It describes a differential model which relates to rate of fish growth w.r.t relevant conditions.


The prior art lacks an integrated and efficient approach to aerate the hypolimnetic region and dispense nutrients while factoring in critical water quality and water body parameters. The current invention aims to provide by real time monitoring of various water quality parameters, carp parameters and provide corrective action by deploying the modules disclosed in the invention in a timely manner. The aeration system modulates oxygen and nutrient dispersal based on input derived using artificial intelligence.


The current invention provides a cost-effective solution that enables timely and corrective action for water body and aquaculture management using predicted values of a wide range of parameters including water quality parameters as predicted by the artificial intelligence module, based on parameters as sensed by sensors comprised in the sensor module.

EXAMPLES
Example 1
Calibration of Sensors in Sensor Module Based on Input From AI Module

DO, pH and ORP sensors were deployed through the sensor module. When DO value between 3<DO<4 ppm,the ORP shows -50mv<ORP<0 and pH between 5<pH<8. This condition is attributed to anaerobic conditions where unionized ammonia values were predicted in the range 0.1<NH3<0.21 ppm. The AI module also repredicted DO value and the value was checked to find the difference in DO value predicted and actually captured from the sensor. If the difference between DO value measured by sensor and DO predicted by Artificial intelligence module is in the range of 0.20- 0.3 ppm constantly for 2 hrs, the prediction corrects the sensor value and flags an alert for calibration and cleaning of sensors.


Example 2
Prediction of Unionized Ammonia, Phosphate, Sulphide and Dispensing of Probiotics/Nutrients

In some conditions, when sensors predicted 2<DO<3ppm,the ORP values -50mv<ORP<0 and and 6.5<pH<7.5, the unionized ammonia were predicted in the range 0<NH3<0.2 ppm, or phosphate >20 ppm, sulphide >20 µg/L or a combination thereof. Probiotics were dispensed by the dispenser of the nutrient dispensing module to balance levels of unionized ammonia, phosphate and sulphide.


Example 3
Aerator Module Functionality Based on Artificial Intelligence Module

It was observed when the sensor values of DO were 4.8<DO<6.4 ppm, the ORP values were, 5mv<ORP<20mv and pH between 6.5<pH<8.5, the aeration module was activated to fill the gap. It was observed that accumulation waste as localised due to stagnation points at the sediment where DO value ranged between 3.5<DO<4.5 ppm, ORP shows -5mv<ORP<15mv, and unionized ammonia between 6.5<pH<8.5, phosphate > 20 ppm, sulphide >20 µg/L as predicted by the Artificial Intelligence module. The unflapped network aerator oscillated with a frequency of 2 Hz to 6 Hz in a phase difference of 90 -180 degrees, while ornithogenic aerator flapped with frequency ranging from 2 Hz to 6 Hz and in a phase difference of 90 -180 degrees to generate asynchronous waves. The phase difference is to create a lag of generating wave such as one wave reaches one destination before second device starts generating wave. The change of frequency was predicted by an AI model of monitoring module taking input data of weather, and sediment water quality parameters.
