Wastewater treatment fermenter

ULTRAWAVES' high-power ultrasonic technology makes it possible to cause disintegration of biomass by cavitation, whose released forces can destroy any robust surface. Of all the plant technologies available on the market for disintegration by ultrasonic, the high-performance ultrasonic systems from ULTRAWAVES are the only ones that are capable of creating hard cavitation. Hard cavitation is the only means of achieving the breakdown of biomass agglomerates and an intensification of the fermentation process. Ultrasonic is sound with frequencies beyond the range of audible sound, i.e. from 20 kHz to the megahertz range. In aqueous media, ultrasonic waves cause periodic compression (pressure) and expansion (tension, negative pressure) of the sonicated medium. High-intensity ultrasonic is necessary to tear apart water molecules during the rarefaction phase, which results in the formation of microscopically small voids in the liquid. These voids become bubbles filled with water vapor or gas. They grow in extension phases and shrink in compression phases, until they implode. This event is called cavitation, a process under extreme (adiabatic) conditions. On a microscale, pressures of 500 bar and a temperature of 5,000 °C are produced. Particularly large cavitation bubbles are produced within the frequency range from 20 to 100 kHz; when these bubbles collapse, they cause extreme mechanical shear forces. These forces produced by ultrasonic are capable of destroying even the most robust surfaces.
