3. The Science Behind Cavitation and Its Role in Water Treatment

Cavitation, a fascinating physical phenomenon involving the rapid formation and collapse of vapor bubbles in a liquid, has garnered significant attention for its transformative role in water treatment. This process, characterized by intense localized energy release, creates extreme conditions such as high temperatures, pressures, and the generation of reactive radicals. These unique properties make cavitation a powerful tool for breaking down pollutants, disinfecting water, and enhancing treatment efficiency. As water scarcity and pollution become pressing global challenges, understanding the science behind cavitation and its application in water treatment offers promising pathways for sustainable and innovative solutions.

Graphic illustration of growth, implosion, and collapse of bubbles in the cavitation process. 1–3: static pressure < vapor pressure ⇨ vapor bubble grows at low pressure; 4: static pressure = vapor pressure ⇨ no further growth of bubbles; 5–15: static pressure > vapor pressure ⇨ implosion and collapse; 9–15: micro-jets

What is Cavitation? The formation and collapse of microscopic bubbles in liquid

Cavitation is a phenomenon characterized by the formation and subsequent collapse of vapor-filled cavities, or bubbles, in a liquid. This process occurs when the static pressure of the liquid drops below its vapor pressure, typically in areas where the liquid experiences high velocities or acceleration, such as in pumps, turbines, and propellers. The bubbles grow as the pressure decreases and can implode violently when they are subjected to higher pressures. This implosion generates shock waves that can cause significant damage to surrounding surfaces, leading to wear and erosion of machinery components.

Cavitation can divided into two main types: inertial (or transient) cavitation, in which bubbles rapidly collapse and produce shock waves, and non-inertial cavitation, in which bubbles oscillate without complete collapse due to external energy inputs like acoustic fields. The rapid formation and collapse of these bubbles can result in localized high temperatures and pressures, which may also lead to chemical reactions beneficial for applications such as water treatment.

In the context of wastewater treatment, hydrodynamic cavitation has been recognized for its potential to degrade organic pollutants effectively. The extreme conditions produced during cavitation facilitate the generation of reactive radicals, such as hydroxyl radicals (OH⋅OH⋅), which play a crucial role in oxidizing contaminants. Studies have shown that this method can significantly reduce levels of harmful substances in water while offering advantages such as lower operational costs compared to traditional advanced oxidation processes (AOPs).Hydrodynamic Cavitation as a low-cost AOP for wastewater treatment

Types of Cavitation in Water Treatment:

Cavitation in water treatment can be divided into two primary types: hydrodynamic cavitation and acoustic cavitation. Each type utilizes different mechanisms to break down pollutants and inactivate microbial cells.

Hydrodynamic Cavitation

Hydrodynamic cavitation involves the use of pressure changes within a liquid to induce the formation and collapse of vapor bubbles. This process typically occurs in devices such as venturi tubes or orifice plates, where the liquid experiences rapid changes in pressure. When the pressure drops below the vapor pressure, bubbles form and subsequently collapse when they enter higher pressure zones. The collapse of these bubbles releases significant energy, generating extreme conditions that can reach temperatures of up to 4600 K and pressures around 1500 bar. These conditions facilitate the degradation of organic substances and bacteria in wastewater, making hydrodynamic cavitation an effective and economical method for water treatment without producing harmful disinfection Hydrodynamic cavitation is a low-cost AOP for wastewater treatment.

Acoustic Cavitation

Acoustic cavitation, on the other hand, utilizes ultrasonic waves to create cavitating conditions in a liquid. In this process, high-frequency sound waves induce pressure fluctuations that lead to the formation of bubbles. As these bubbles grow and collapse, they generate localized high temperatures and reactive species, which can effectively inactivate microorganisms and degrade pollutants. Acoustic cavitation is particularly useful for disinfection purposes due to its ability to target specific contaminants at lower energy levels compared to hydrodynamic methods. However, it often involves higher operational costs and is generally more suited for smaller-scale applications Cavitation-Based Processes for Water and Wastewater Treatment.
