This patent specification relates to the field of water body algae control systems and methods. More specifically, this patent specification relates to a system and method for controlling algae growth in water bodies using nanobubble oxygen.
Algae blooms are one of the most significant environmental issues affecting all types of water bodies today. They impact recreation use of lakes and ponds, drinking water sources, and contribute to health problems when humans and animals contact some of the algal species that release toxic compounds into the water and surrounding air.
Various forms of green and blue green (cyanobacteria) algae are naturally present in most water bodies such as lakes and ponds. These algae can be beneficial to aquatic life in small quantities as fish and other animals consume algae as a food source. Algae are plants that utilize photosynthesis to live. They produce oxygen during the daytime hours, using solar energy to convert carbon dioxide in the atmosphere into oxygen needed for respiration. This generates dissolved oxygen (DO) in the upper portions of the water body where sunlight can penetrate vertically into the water column and algae are present.
The algae receive nutrients such as phosphorus and nitrogen, that are required by the plants for survival, from the water column and from the bottom of the water body. These nutrients are in higher concentrations as surface runoff, fertilizer deposition, and other contributors are washed into the water body over time. Anaerobic conditions in the sediment layer in the bottom of the water body favor release of these nutrients into the water column where they are made available for the algae plants in the upper portion of the water column.
DO levels increase and decrease in the upper portions of the water column based on the action of algae and physical factors such as wave actions that entrain oxygen in the surface water. At night, or on cloudy days when sunlight is not abundant, algae consume DO and release carbon dioxide to the water column. If DO levels are sufficiently depleted by algae, negative impacts on aquatic life such as fish kills can occur as free oxygen is no longer available to sustain life.
Control of various types of algae, in particular blue green algae (also known as cyanobacteria) and harmful algal blooms (HABs), in water bodies may be conducted by applying various chemicals to damage or kill the algae plants. These include copper sulfates (algaecides) and oxidizing chemicals such as hydrogen peroxide, peroxyacetic acids, and chlorine compounds. Many of these chemicals can cause health impacts to humans and animals that utilize the water from the pond or lake. These chemicals may also cause unwanted side effects on water quality or eventual use of the water in the water bodies for irrigation or other purposes. Additionally, when water from the water body is applied to soil via irrigation methods, negative impacts can be created that decrease microbial life in the soil.
Therefore, a need exists for novel water body algae control systems and methods. A further need exists for novel water body algae control systems and methods that do not utilize chemicals can cause health impacts to humans and animals that use the water. There is also a need for novel water body algae control systems and methods that do not cause the water of the water body to negatively impact soil microbial life, such as when used for irrigation purposes.
A method and system for water body algae control is provided. The method and system may be used to provide nanobubbles of an oxygen containing gas and/or an ozone containing gas into a water body which will quickly react with algae and other organic contaminants. Preferably, the nanobubbles may increase aerobic conditions in the bottom of the water body, and bioaugmentation and biostimulation products may be utilized to increase microbial activity to consume nutrients such as phosphorus and nitrogen and reduce access of these nutrients to the algae plants in the upper portions of the water bodies, thus limited algal growth. Preferably, ozone nanobubbles may be formed along with oxygen nanobubbles and may be effective in oxidizing algal cells and other water contaminants. Ozone nanobubbles break down into oxygen and water - providing oxidation without harsh chemicals.
In some embodiments, a method for water body algae control in a water body may include the steps of: withdrawing water from the water body; infusing a gas containing oxygen and/or ozone into the withdrawn water by generating nanobubbles of the gas within the water; and returning the infused water into the water body.
In some embodiments, a water body algae control system may include a nanobubble generator that may be configured to receive water that is withdrawn from a water body. An oxygen concentrator and an air compressor may be configured to provide a gas containing oxygen and/or an ozone generator may be configured to provide a gas containing ozone to the nanobubble generator. The nanobubble generator may be configured to disperse nanobubbles of the gas containing oxygen and/or a gas containing ozone into the water, and in which the nanobubble containing water is then returned back into the water body.
According to one aspect consistent with the principles of the invention, the system may comprise and/or the method may utilize a portable platform mounted on wheels which may be include an oxygen generation system preferably including an air compressor and an oxygen concentrator, an ozone generator, a nanobubble generation unit, monitoring and control equipment and associated plumbing which may be towed or otherwise moved to be proximate to a water body and/or a desired location along the water body.

Additionally, these sequences of actions described herein can be considered to be embodied entirely within any form of computer readable storage medium having stored therein a corresponding set of computer instructions that upon execution would cause an associated processor to perform the functionality described herein. Thus, the various aspects of the invention may be embodied in a number of different forms, all of which have been contemplated to be within the scope of the claimed subject matter. In addition, for each of the embodiments described herein, the corresponding form of any such embodiments may be described herein as, for example, “logic configured to” perform the described action.
The control unit 50 may also include a main memory, such as a random access memory (RAM) or other dynamic storage device (e.g., dynamic RAM (DRAM), static RAM (SRAM), and synchronous DRAM (SDRAM)), coupled to the bus for storing information and instructions to be executed by the processor 51. In addition, the main memory may be used for storing temporary variables or other intermediate information during the execution of instructions by the processor 51. The control unit 50 may further include a read only memory (ROM) or other static storage device (e.g., programmable ROM (PROM), erasable PROM (EPROM), and electrically erasable PROM (EEPROM)) coupled to the bus for storing static information and instructions for the processor 51.
In some embodiments, the method 500 may start 501 and water may be withdrawn from a water body 99 in step 502. In some embodiments, water may be withdrawn from a water body 99 via an intake pump 15 that may comprise a submersible pump so that the intake pump 15 may be positioned underwater in the water body 99, and more preferably on the bottom of the water body 99 to allow the intake pump 15 to intake water from the bottom of the water body 99. In further embodiments, water may be withdrawn from a water body 99 via an intake pump 15 that may be coupled to a conduit (fourth conduit 34 in
After step 502, the method may proceed to step 503 and/or to step 504.
In step 503, a gas containing oxygen may be infused into the withdrawn water by generating nanobubbles of the gas within the water. In some embodiments, the withdrawn water may be communicated to a nanobubble generator 12 which may infuse the gas containing oxygen into the water by generating nanobubbles of the gas within the water. Preferably, an oxygen concentrator 13 and an air compressor 14 may provide the gas containing oxygen and to the nanobubble generator 12 which may then disperse nanobubbles of the gas containing oxygen into the water. In preferred embodiments, the nanobubbles may be sized less than approximately 800 nanometers (nm), more preferably sized less than approximately 500 nanometers (nm), and more preferably sized less than approximately 200 nanometers (nm). In further preferred embodiments, the nanobubbles may be generated in the water at concentrations over approximately 1.0 x 10^5 nanobubbles per milliliter, and more preferably at concentrations over approximately 1.0 x 10^8 nanobubbles per milliliter. In further preferred embodiments, the gas containing oxygen may have oxygen gas at a concentration of greater than approximately 90 percent by volume, more preferably at a concentration of greater than approximately 93% by volume, and still more preferably at a concentration of greater than approximately 95% by volume. In still further embodiments, the nanobubbles may be generated by a nanobubble generator 12 that may be coupled to a portable platform 71 having a ball-mounted hitch 72. In still further embodiments, the gas containing oxygen may be supplied to the nanobubble generator 12 by an oxygen generator 13 that is coupled to a portable platform 71 having a ball-mounted hitch 72. In yet further embodiments, the water may be withdrawn from the water body 99 via an intake pump in step 202, and the intake pump 15 may be interlocked to only operate when the gas containing oxygen supplied to the nanobubble generator 12 has a gas pressure at a minimum of approximately 10 pound per square inch.
In step 503, a gas containing ozone may be infused into the withdrawn water by generating nanobubbles of the gas within the water. In some embodiments, the withdrawn water may be communicated to a nanobubble generator 12 which may infuse the gas containing into the water by generating nanobubbles of the gas within the water. An ozone generator 20 may provide a gas containing ozone to a nanobubble generator 12. Preferably, an oxygen concentrator 13 and an air compressor 14 may provide a gas containing oxygen to the ozone generator 20, and the ozone generator 20 may use the gas containing oxygen to generate a gas containing ozone that the nanobubble generator 12 may then use to disperse nanobubbles of the gas containing ozone into the water. In preferred embodiments, the nanobubbles may be sized less than approximately 800 nanometers (nm), more preferably sized less than approximately 500 nanometers (nm), and more preferably sized less than approximately 200 nanometers (nm). In further preferred embodiments, the nanobubbles may be generated in the water at concentrations over approximately 1.0 x 10^5 nanobubbles per milliliter, and more preferably at concentrations over approximately 1.0 x 10^8 nanobubbles per milliliter. In further preferred embodiments, the gas containing oxygen may have oxygen gas at a concentration of greater than approximately 90 percent by volume, more preferably at a concentration of greater than approximately 93% by volume, and still more preferably at a concentration of greater than approximately 95% by volume. In still further embodiments, the nanobubbles may be generated by a nanobubble generator 12 that may be coupled to a portable platform 71 having a ball-mounted hitch 72. In still further embodiments, the gas containing ozone may be supplied to the nanobubble generator 12 by an ozone generator 20 that is coupled to a portable platform 71 having a ball-mounted hitch 72. In yet further embodiments, the water may be withdrawn from the water body 99 via an intake pump in step 202, and the intake pump 15 may be interlocked to only operate when the gas containing ozone supplied to the nanobubble generator 12 has a gas pressure at a minimum of approximately 10 pound per square inch.
In step 505, the infused water may be returned into the water body 99. In preferred embodiments, the infused water is returned to the bottom of the water body 99. Generally, the bottom of a water body 99 may refer to any depth greater than approximately three feet below the surface of the water body 99. After step 505 the method 500 may finish 506.
