Analysis and design of high-frequency sound wave generator for algae removal

Currently, the application of high-frequency sound waves in the high-frequency or ultrasonic frequency range is a widely adopted technology utilized across various sectors including industrial, agricultural, environmental, and research and development. The application of high-frequency sound wave technology entails the generation of vibrations transmitted through a medium to a target. A distinguishing feature of this technology is its chemical-free nature, versatility, and energy efficiency. High-frequency sound wave technology involves the conversion of electrical energy into mechanical energy. Operationally, when the high-frequency electrical signal generation system initiates the transmission of electrical signals through a signal conductor to the high-frequency sound wave emitting device, electrical phenomena occur, resulting in vibration generation. The design of the system allows for the adjustment of operating frequencies according to usage requirements, rendering this technology intriguing. Consequently, our research team recognizes the significance of applying high-frequency sound waves in the eradication and control of algae in water sources. We have designed the system to enable frequency adjustment within the range of 20 to 100 kilohertz for analyzing the impact of propagated waves through water, which serves as a medium for algae eradication. Additionally, we consider the electrical power consumed as a result of its effect on the vibration intensity of the high-frequency sound wave emitting device, influencing the wave distribution radius. Notably, the algae eradication system employing high-frequency sound waves operates without adverse effects on aquatic life, making it environmentally friendly. This technology enhances water safety, promotes energy conservation, and exhibits high operational efficiency without the need for chemical agents.
