DETAILED DESCRIPTION

[0028] The present patent application refers to a remote control apparatus such as a boat or a similar surface, partially submersed or fully submersed apparatus. The apparatus is driven from shore using a commercially available long-range transmitter (44, FIG. 1 and FIG. 2) and receivers on the remote controlled elements on the boat. A remote controlled servo (24, FIG. 4) on the apparatus regulates the speed of the motor (22, FIG. 1, FIG. 2, FIG. 3 and FIG. 4) while another remote control servo (25, FIG. 4) adjusts the rudders (26, FIG. 4) to control the direction. The length or the width of the apparatus can range from 1 foot to 30 feet. For simplicity, the apparatus here described is referred to as “boat” (1, FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6 and FIG. 7). The power source (4, FIG. 1, FIG. 2 and FIG. 3) can be gas, gas mixed with oil, batteries, solar panels, a gas-driven electrical generator or an electrical marine cable or other suitable cable from the shore of the body of water. The apparatus can have one of various propelling configurations such as a propeller-driven boat, a water-jet propelled boat or one of any configuration or shape that allows it to travel on water, partially submersed in water or underwater. Some of the preferred configurations are those that reduce the chance of the apparatus getting tangled in roots or vegetation such as an airboat with air propeller blades (6, FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 7).

[0029] The apparatus and methods of the patent application allow the safe evaluation of the health of bodies of water by taking readings, samples and mapping sludge sediments via remote control. It is dangerous for a person to get on a boat in contaminated bodies of water because wind can spray water, the person can fall overboard or because toxic gasses may emanate from the body of water. Once the root problems affecting the body of water have been determined, a bioremediation strategy can be developed. The boat has the capability to apply such remediation products.

[0030] The boat uses several probes or a multi-parameter probe (2, FIG. 1) to take readings at any depth of the water column or into the sludge blanket at the bottom of the body of water. Some of these parameters that can be read are pH, temperature, conductivity, salinity, turbidity, total dissolved solids, dissolved oxygen, oxidation-reduction, ammonia, nitrate, phosphorous as well as algae and chlorophyll levels. The metering devices and receivers of the remote controlled elements are protected by an enclosure (10, FIG. 1) or a low-weight roof to prevent damage from the rain or water sprayed by the wind. The probe is reeled down with a remote-control reel (7, FIG. 1) on the boat. The metering device connects to the multiparameter-probe or probes (2, FIG. 1) via a cable (18, FIG. 1). The data from the probe is either stored on an onboard memory device on the boat or it is transmitted to a receiver with visual interface (9, FIG. 1 and FIG. 2) at shore (42, FIG. 1, FIG. 2, FIG. 3, FIG. 7) via telemetry. The data would include the location and depth where the reading is taken using the GPS (20, FIG. 1, FIG. 2 and FIG. 3) on the boat which transmits its location via telemetry. The depths where the readings are taken are obtained from a pressure sensor (8, FIG. 1 and FIG. 2) with telemetry. The probes can take and send continual readings or they can be turned on only at the desirable locations. The data is streamed in real-time without having to return to shore to read it. In this manner, the apparatus monitors the different parameters at different locations and depths to find trouble spots and get the needed data and samples to troubleshoot the body of water. The receiver display interface can be a smart phone, tablet, laptop or other suitable platform that is compatible with the telemetry system.

[0031] There are companies such as In-situ in the United Kingdom that sell multi-parameter devices with the option of telemetry. In addition, a telemetry system can be designed where the probes are connected via their BNC connectors to an electrode amplifier and to an interface. The amplifier increases the voltage produced by the electrode probe into a range where it can be monitored by an interface device. A transmitter-receiver module streams data wirelessly in real-time at standard frequencies used in commercial systems. The telemetry can be any of the commercially available ethernets, GOES satellite, spread-spectrum radio etc. The interface can have multiple channels to monitor more than one device at the same time.

[0032] The apparatus can also do sludge blanket mapping using a fish-finder sonar. The sonar (3, FIG. 1 and FIG. 2) on board has telemetry capability and it can map the thickness of the blanket of sludge that builds up at the bottom of wastewater treatment lagoons or ponds, contaminated recreational bodies of water. The sonar is one of various commercially available models with mapping capability and with the necessary frequency to detect sludge sediments. The sludge blanket thickness is measured before bioremediation begins and can be measured during the bioremediation procedure to determine its effectiveness or if a different bioremediation approach is needed to better digest the sludge blanket.

[0033] The sonar transducer (11, FIG. 1 and FIG. 2) sends and receives sound waves. The signals are sent to the sonar unit (3, FIG. 1 and FIG. 2) which uses telemetry to transmit the data to shore. At shore, the data is captured by a receiver unit with a visual interface (9, FIG. 1 and FIG. 2). The data can also be stored in an onboard interface storage device to be read later. The sonar reads sludge levels by transmitting pulses of sound energy into the water and detecting the sound energy reflected back to the transducer (11, FIG. 1. and FIG. 2). The time that is required for the reflected sound energy to return to the transducer correlates with the depth of the reflecting object. The sludge blanket can be distinguished from the lagoon bottom by the difference in density. The difference in density is viewed in the image as difference in colors. Numerical data of depths is also provided by the sonar system. Typical transducers range in frequency from 50 kHz to 800 kHz. In order to map sediment sludge in the shallow waters of wastewater ponds or lagoons (20 feet or less), a high frequency is needed. Higher frequencies have shorter wavelengths and more wave cycles per second. This provides a higher definition picture that can map the sludge blanket thickness in spite of its low density and differentiate it from the higher density of the bottom of the body of water. In this application, frequencies of 400 kHz to 800 kHz can be used. The thickness and distribution of the sludge blanket throughout the body of water is essential to apply bioremediation products at the proper locations for its digestion. In addition to the ability to map sludge, the volume of the sludge blanket throughout the body of water can be calculated using commercial software (Biobase in Minneapolis). This is useful to monitor and evaluate the degradation of sludge using biological bioremediation products in lagoons or ponds. Such process is known in the industry as bio-dredging.

[0034] In deep water (over 20 ft.), a lower frequency transducer such as one lower than 200 kHz is normally used to map sludge at the bottom of contaminated recreational bodies of water or others. This allows for deeper penetration of the signal into the water. The signal sent from the sonar is projected downward as a “cone”. A sonar beam's cone angle indicates the extent to which a transmitted beam “spreads out” as it travels through the water column. The area covered at the bottom of the cone depends on the angle of the signal and the depth of the body of water. For shallow water, a wider cone angle is commonly used to make the area under observation large enough to be useful. However, if the angle is too wide, the signal is more susceptible to being scattered in an unproductive way by small objects in the water. In order to map sludge in the shallow water of wastewater plants (20 feet or less), lagoons or ponds, a narrow cone angle of 8 degrees to 20 degrees is useful to achieve higher resolution by concentrating the signal on a small area at the base of the cone. For deeper water, a small cone angle (8 degrees or less) is used because the distance traveled in the water column is longer increasing the area at the base of the cone at the bottom of the body of water. The smaller cone angle is necessary to avoid loss of resolution in the wider area of deep lagoons or ponds.

[0035] A multiple frequency sonar can also be used. Different frequencies reveal different levels of detail. For example, a high frequency pulse provides excellent detail, but cannot penetrate very deep into the water. A low-frequency 50 kHz pulse penetrates deeper, but reveals less detail. A multiple frequency transducer has a broad band system that uses multiple frequencies at the same time improving resolution. CHIRP (an acronym for Compressed High Intensity Radiated Pulse) is such a system which generates an image using a wider range of frequencies allowing the processor to produce a much more accurate and detailed sonar image at different depths. Lowrance sells fish-finder sonar systems with the right frequency and cone angle that allows the measurement of the sludge blanket in wastewater bodies which normally have a water column of 20 feet or less. Lowrance also has units that can map sludge at deeper depths.

[0036] The remote-control boat can take water or sludge samples. The samples can be taken at different depths of the water column or at the bottom of the body of water for further laboratory analysis. The location where the sample is taken is monitored using the onboard GPS (20, FIG. 1, FIG. 2 and FIG. 3) with telemetry and the depth where the sample is taken is recorded by the pressure sensor (8, FIG. 1, FIG. 2 and FIG. 7) also with telemetry capabilities. The body of water can be a contaminated recreational body of water or wastewater lagoon or pond. The sample can be obtained using a “bacon bomb” sampler (5, FIG. 2) which is a device commonly used to take samples from the bottom of tanks or petroleum and gasoline containers. The bacon bomb can be lowered using an on board remote controlled reel (7, FIG. 1) similar to the one used to lower the probes or it can use a hose reel (35, FIG. 2.) for the same purpose. The bacon bomb (5, FIG. 2) hits the bottom and a plunger assembly opens to admit the material. The plunger closes again when the bacon bomb is withdrawn, forming a tight seal. The boat can carry several remote controlled reels (7, FIG. 1) to lower the probe or probes and remote controlled reels (35, FIG. 2) to lower the sampling devices.

[0037] A hose can also be used and be reeled down from the boat to the desired depth using a remote-controlled hose reel (35, FIG. 2) previously described. The hose can be used to obtain a sample. If a hose is used to get the sample, the hose would be attached to a remote controlled self-priming pump (12, FIG. 2) on the boat which would withdraw water from any point in the water column or sludge from the sludge blanket. The sample hose (23, FIG. 2) would have a check valve (19, FIG. 2) at its submerged end to prevent liquid from entering the hose as the hose is reeled down. When the pump is engaged, the pump suction overcomes the check valve and withdraws the sample in the direction that the valve is designed to do. When the pump stops, the valve closes keeping the sample in the hose. The sample can be emptied into an onboard container or it can be kept in the hose and be withdrawn at shore. When the suction pump stops, the check valve closes and keeps the sample inside the hose. Alternatively, a bladder pump system can be used to get a sample. These types of pumps are commonly used to collect ground water samples. The pump can be controlled via remote control from shore and the sample can be collected on an onboard container on the boat. Other similar devices to take water or sludge samples can also be used such as a modified sludge judge or other.

[0038] Several remote control reels on the boat can be used to obtain various samples via “bacon bombs”, hoses or bladder pumps. The operator can keep track of where the samples were taken by recording the GPS locations. The pump or bacon bomb that holds any of the samples can be easily determined by which reel or pump is activated when the sample is taken. As an alternative to a pressure sensor to determine depth, the depth can also be approximated counting the turns of the reel and using the average diameter to determine the number of circumferences to approximate depth. The turns can be counted with an infrared sensor as well as a mechanical or digital tachometer that streams the data to shore in order to stop the reel when the desired depth is reached.

[0039] The reel can be a small commercially available remote control unwind and rewind reel sold by various distributors such as Pacific Marine & Industrial in Richmond, Calif. A reel can also be designed with a DC motor or servo that has the ability to reverse polarity to wind and unwind. The reel would lower the probe with an appropriate cable with BNC connectors compatible with the metering probe or sensors. A similar remote controlled reel or reels can be used to lower the sampler device or the sampling hose previously described as well as the application hose (13, FIG. 1).

[0040] The boat can carry a delivery system to apply bioremediation products to degrade contaminants, digest sludge, control odor, control excess algae, reduce coliform counts, eliminate toxicity and improve the overall performance and health of the body of water. In one configuration, the bioremediation products can be carried in the hull of the boat. A self-priming pump on the boat (17, FIG. 3) sends the bioremediation product via an application hose (13, FIG. 3) that can be lowered with an onboard reel (36, FIG. 3) or just hang at the depth where the product needs to be applied. The application hose (13, FIG. 3) carries a plastic weight (34, FIG. 3) at its end to keep the hose extended at its full length. Alternatively, the boat can be connected to shore (42, FIG. 3) via a bioremediation hose (14, FIG. 3). The bioremediation hose can refill the hull of the boat so that it does not need to return to shore. On shore, the bioremediation hose is connected to an on shore reel (29, FIG. 3). The reel in turn is connected to a pump (15, FIG. 3) which draws the bioremediation product from a large tank (16, FIG. 3) or from an onsite bioreactor (21, FIG. 3). The onsite bioreactor can be one such as U.S. Pat. No. 10,981,818 B2 which would grow microorganisms on site and apply them at the end of the fermentation cycle when their numbers are the highest. The boat can carry remote controlled reels for the probes (7, FIG. 1), for sampling devices (35, FIG. 2.) and to lower the bioremediation hose (36, FIG. 3).

[0041] On a different configuration, the bioremediation hose (14, FIG. 5) can bring the bioremediation product from shore and apply it directly to the body of water without the need of a remote controlled reel on the boat. In this configuration, the hull does not need to carry the bioremediation product to reduce the weight and drag on the boat motor. For this purpose, the boat would have a plate (30, FIG. 5) made of corrosion resistant material such as stainless steel or other. The plates have corrosive resistant connector tubes (31, FIG. 5) welded to it. On the top of each connector tube there is a swivel (32, FIG. 5) where the bioremediation hose (14, FIG. 5) from shore connects. The swivel connected to the hose reduces the chance of the bioremediation hose from tangling as the boat changes direction. On the lower part of the connector tube, the application hose (13, FIG. 5) can be connected to deliver the bioremediation product. The length of the application hose can be selected to apply the bioremediation product at the bottom of the body of water under the sludge blanket or at any point in the water column. A plastic weight at the end of the hose ensures that the application hose is extended to the full length. When the bioremediation hose applies the bioremediation product from the pump on shore (15, FIG. 3), it is desirable that the application stops when the pump on shore is turned off. In this manner, bioremediation product is not wasted as the boat moves to a new location for product application. In order to stop application when the pump at shore is turned off, a one-way valve (43, FIG. 3) is placed on the bioremediation hose (14, FIG. 3) close to the boat. When the pump on shore (15, FIG. 3) is turned on again, it produces enough pressure to push the one-way valve in the direction of the flow.

[0042] In a preferred alternative configuration, bioremediation product and air are fed to the boat from shore (42, FIG. 7). They would be fed from a double hose such as a welding hose. In a welding hose or similar double hose, both hoses are attached to each other (37, FIG. 6) and they can be fed independently. On shore, bioremediation product is fed from either a large container (16, FIG. 7) or a bioreactor (21, FIG. 7) to a double-hose reel on (29, FIG. 7) on shore. In order to stop the feed of the bioremediation product, the pump on shore (15, FIG. 7) is turned off. A one-way valve (43, FIG. 7) on the hose feeding the bioremediation product stops the feed. When more bioremediation product needs to be fed, the pump (15, FIG. 7) is turned on and the flow of the bioremediation product opens the one-way valve. In this preferred configuration, air is fed from the compressor (28, FIG. 7) also to the same double hose reel on shore (29, FIG. 7). From the double reel on shore, the double hose bioremediation hose (37, FIG. 6 and FIG. 7) brings to the boat bioremediation product in one line and air in the other. The double hose connects to swivels (32, FIG. 6 and FIG. 7) which are attached to two connector tubes (31, FIG. 6 and FIG. 7). From the bottom of the connector tubes, a double hose (40, FIG. 7) connects to a small double hose reel on the boat (36, FIG. 7). This reel lowers the application double-hose (38, FIG. 7) to the desired depth. The application hose line carrying air has a diffuser (33, FIG. 6 and FIG. 7) at its end. The small bubbles coming out from the diffuser mix and disperse the bioremediation product exiting from the other hose line which applies the bioremediation product. The air bubbles also provide oxygen for increased biological activity. The double-hose application hose carries a plastic weight (34, FIG. 6 and FIG. 7) to allow the hose to be fully extended. The depth required to lower the double hose is measured with the pressure sensor (8, FIG. 7) and the information is sent to shore via telemetry.

[0043] To reduce the drag of the weight of the bioremediation hose, hollow floats can be attached to the hose every few feet as the hose leaves the on shore reel. Hollow floating sticks (41, FIG. 6.) such as the ones used in swimming pools can be used. The floats can be of a color which makes them visible from far to see how the hose is extending. As the boat finishes its task and the hose is reeled back from shore, the floats can be removed as the hose is reeled back.

[0044] If more efficient oxygenation of the body of water is required, nanobubbles can be pumped from a nanobubble generator at shore. Nanobubbles are less than 200 nanometers in diameter and have no buoyancy. They are not lost to the atmosphere; instead, they remain in water until their oxygen content is utilized. Nanobubbles can be produced from air, pure oxygen or from ozone. Nanobubbles also have strong disinfecting power. If it is necessary to reduce pathogen numbers, cyanotoxins and algae as well as to break down cyanotoxins, then nanobubbles can be used. Nanobubbles ability to disinfect and break down cyanotoxins increases based on their composition. Air has the least disinfecting power, pure oxygen has stronger disinfection characteristics and ozone is the most powerful. Nanobubbles lose their disinfection capacity over time. Their disinfection power can be assessed with an oxidation-reduction probe such as the ones used by the apparatus in this patent application. Once the disinfection power has subsided, bioremediation microorganisms can be applied with the apparatus to outcompete the remaining coliforms and pathogens.

[0045] If the bioremediation products used for a body of water are microorganisms, they can be grown onsite with a bioreactor (21, FIG. 3 and FIG. 7)) The bioreactor such as in U.S. Pat. No. 10,981,818 B2 can produce large amounts of concentrated microorganisms. The microorganisms used for bioremediation are safe because they are non-pathogenic and non-genetically modified. The microorganisms are selected depending on what problems are present in the body of water. For example, Nitrosomonas and Nitrobacter nitrify excess ammonia converting it into nitrate. Another set of bacteria such as Pseudomonas, Thiobacillus and Paracoccus denitrify nitrate and produce nitrogen gas allowing the removal of nitrogen from water. Other bacteria oxidize hydrogen sulfide, mercaptans and other sulfur compounds controlling their toxicity and malodor. Various contaminants including organic toxicants can be eliminated by digestion using the selected microorganisms. Some microorganisms that can be used in bioremediation are bacteria, fungi, actinomyces, streptomyces, protozoa and metazoa. All these types of specialized microorganisms are known in the field of bioremediation and can be purchased from various suppliers such as Novozymes in Franklinton (N.C.), Sustainable Nutrition in Jefferson City (TN) and others. In the art of bioremediation, enzymes are also used. An enzyme is a protein capable of degrading a specific pollutant. If many different types of pollutants need to be degraded, a blend of enzymes can be used. Enzymes can be purchased from Novozymes, CEKAL in Mount Holly (NC) and multiple suppliers. Biostimulants are also used in the art of bioremediation. Their function is to enhance the ability of the biology in the body of water to improve pollutant degradation as well as to enhance the efficiency of bioremediation microorganisms that are applied. Biostimulants are based on micronutrients and plant extracts. If the body of water is deficient in macronutrients such as nitrogen and phosphorous and if this deficiency is not allowing the biology to digest contaminants, macronutrients can be applied. Sometimes, it may be necessary to add oxygen to a septic portion of the body of water to activate its biology. There are several chemicals that provide oxygen such as sodium perborate, calcium peroxide, magnesium peroxide, calcium nitrate, potassium nitrate and various nitrate containing chemicals. If there is a need to precipitate phosphates in the body of water to control eutrophication, a phosphate precipitant product can be used to make the phosphates biologically unavailable. Some of these chemicals are salts of cationic ions such as ferrous salts, ferric salts, aluminum salts and lanthanum salts. If the body of water is heavily contaminated with coliforms and various pathogens and if there is a need to control their numbers, nanobubbles can also be applied as part of the bioremediation process.

[0046] Although the apparatus and methods described in the patent application have been described with reference to the preferred embodiments, it will be understood by those skilled in the art of bioremediation that changes in form and detail may be made therein without departing from the spirit and scope of the invention.
