9 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Physics principles: waves In terms of physics a wave is a perturbation that propagates through a medium. Ball movement over time describes a wave.

10 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Physics principles: waves Time A a = A·sen(ωt) // ω = 2π·f For one complete oscillation T, the frequence f is the number of oscillations per second, termed as f = T -1 A complete oscillation takes a T time (Period)

11 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Acoustic waves: types Ultrasound AcousticInfrasound 20 Hz 20 kHz Sound is a wave where excited magnitude is pressure (vertical axis is A = P). Ultrasound is a type of acoustic wave where the frequence is higher than 20 kHz (human limit). In the same way as sound, ultrasound needs a medium to propagate (wastewater or sludge).

12 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Ultrasonic waves Successive pressures (+) and (-) cause particles movement and wave propagation. (A) is the amplitude and determines power (P), (P = E/t, E = mω 2 A 2 /2) and intensity I (I = P/S), measured in (W/cm 2 ).

13 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Ultrasonic Cavitation When pressures (+) and (-) take place under frequences about 20 kHz and intensities between 25 and 50 W/cm 2, the medium breaks and produces small bubbles. This phenomenon is known as Ultrasonic Cavitation.

14 DUMO Ultralyzer technology to optimize WWTP process DUMO Ultralyzer technology to optimize WWTP process 2. Ultrasound science Creation and implosion of the cavitation bubbles Ultrasonic cavitation is the process consisting of bubble creation, growth, and collapse by implosion.
