The DUMO Ultralyzer system aims to increase the efficiency and generate high performance in the treatment of sludge generated in wastewater treatment plants.
Ultrasound is a pressure wave that propagates through a medium.
The successive pressures (+) and (-) cause the particles to move and propagate the wave.
The wave amplitude (A) determines the power (P), (P = E/t, E = mω2A2 / 2) and especially the intensity I (P/S), which is measured in (W / cm2).
When the (+) and (-) pressure sequence takes place at 20 kHz and 25 W / cm2, ultrasonic cavitation occurs, which causes the liquid to fracture, forming microscopic bubbles filled with plasma.
Ultrasonic cavitation is the creation, growth and collapse by implosion of these microscopic bubbles.
The cavitation bubbles reach up to 5000° C temperature and 500 atmospheres pressure.
Effect of cavitation on biomass.
These extreme conditions produce from flocculent disintegration to cellular disintegration (lysis), and are the foundation of DUMO Ultralyzer.
Under these conditions, we will get:
The hydrolysis of the BOD hardly biodegradable generates the following:

BULKING & FOAMING
The disintegrated secondary sludge and recirculated to the denitrification zone, is a magnificent source of rapidly biodegradable carbonaceous matter.
