Abstract

The present invention relates to an apparatus for controlling a biological organism using a sweeping frequency emitted by an underwater ultrasonic transducer. The ultrasonic control system comprises a processor, an exciter, and at least one transducer. The processor generates a signal received by the exciter that causes the transducer to emit a series of sweeping frequencies coupled with a pulse or gate output having a duty cycle. Each pulse or gate output includes one or more frequencies. The apparatus has a progressive purification start mode for controlling high algae concentrations. A plurality of stages progressively neutralize the algae until a steady-state stage can maintain algae level control. The first purification stage has an extended off-time between pulses. The next stage reduces the off-time between pulses until a final, steady-state stage.

Statements regarding federal government-funded research or development Not applicable background 1. Field of Invention The present invention relates to controlling algae, biofilms, diatoms, and bio-organisms in a body of water by field sweeping of ultrasonic sound pressure frequencies. More specifically, the present invention relates to an underwater ultrasonic system that emits a series of sweeping frequencies to control specific organisms in a liquid. 2. Description of related technology Algae are a group of large, diverse photosynthetic organisms that often thrive in aquatic environments. Algae flourish when bodies of water are rich in nutrients. Depending on the type of algae, algal growth can be beneficial or harmful to the health of the water body. For example, filamentous green algae and cyanobacteria are known to have an adverse effect on the health of water bodies when they grow in abundance. Filamentous green algae are generally considered a nuisance that interferes with boater access, recreation, and the aesthetics of water bodies. Green algae grow in mats, which can be physically removed from the water by raking or other means. Excessive cyanobacteria form a surface bloom, which is a thick scum on the surface, typically near the shore. Some species of cyanobacteria produce strong toxins that affect other aquatic life and animals. Cyanobacteria are not edible, and generally, they produce an unpleasant odor when they decompose. The control of undesirable algae, such as unicellular, colonial, and filamentous green algae and cyanobacteria commonly known as blue-green algae, can be achieved by controlling the supply of nutrients in the water. Without sufficient nutrients, algal growth will be limited. Unfortunately, controlling nutrients within a body of water is often difficult because controlling the inflow of nutrients into the body of water requires controlling the watershed. Both stormwater drainage and agricultural drainage provide nutrients, and such sources are often difficult to manage. Controlling undesirable algae by introducing chemicals into bodies of water creates additional problems, particularly when the water contains other plants or animals commonly found in lakes, ponds, and streams. When the water is a swimming pool, hot tub, or spa, chemicals are often used to control or eliminate undesirable algae growth. Another way to control undesirable algal growth is to reduce or eliminate the sunlight that algae require for photosynthesis. Floating plants, such as water lilies and lotus flowers, block sunlight from penetrating the surface, thereby limiting the light reaching the algae. Other aquatic plants grow in the water and absorb the nutrients that algae need to thrive. For many bodies of water, such as lakes or large ponds, adding plants is not practical. According to one embodiment of the present invention, an algae control system is provided that emits ultrasound from a transducer excited to a frequency sweeping a variety of ranges. The algae control system emits ultrasonic sound pressure frequency waves at frequencies lethal to living organisms and inhibits the aggregation of some inanimate objects, such as biofilms. The ultrasonic frequency is emitted at a frequency that matches or nearly matches the structural resonance of major components within the algae, such as vacuoles, internal cellular structures, and motor components such as flagella, thereby killing or incapacitating the organisms. The mechanism causing algae death varies depending on the type of algae. For most algae, ultrasound incapacitates the algae, causing them to sink. As the algae sink, their exposure to sunlight decreases, and over time, the algae die. To achieve critical structural resonance, a specific frequency needs to be applied to each of the various species of algae. In one embodiment, critical structural resonance is achieved for the various algae by emitting a frequency spectrum, e.g., from 20 kHz to 120 kHz, which is generated at discrete frequencies such as every 100 Hz between 20 kHz and 120 kHz, resulting in 1,000 discrete frequencies. If each discrete frequency is generated once per second, 1,000 seconds are required before the frequency generation pattern is repeated. Only one of the 1,000 frequencies may be effective in achieving critical structural resonance. Generally, not all organisms within a harmful algal bloom (HAB) or colony will be incapacitated during a single sweep. If the sweep is too long, the HAB or colony will survive and grow sufficiently to rebuild the losses incurred during a single sweep. Increasing the number of frequencies generated per second will cause the HAB or colony to receive sufficient death or incapacitation events, thereby preventing the HAB or colony from surviving.
