THE CELL DESTRUCTION UNIT - HOW IT WORKS

The CDU uses a series of intricate stators and rotors with varying channels and chambers to produce high sheer and extreme pressure fluctuations. These pressure fluctuations produce cavitation in the chambers. When pressures are reduced to below the vapour pressure of the liquid, small bubbles form and collapse. Extremely high temperatures and pressure gradients are produced in the vicinity of the collapsing bubbles.

These violent forces and a wide range of sound frequencies are transmitted throughout the liquid body as shock waves that disseminate four times faster than the speed of sound in air. The combined physical actions break organic matter encasing pathogens, denaturing and rupturing cell walls to destroy bacteria, viruses, parasites and EDCs.

A small amount of oxidant (ozone) is incorporated into the liquid mass by gas-liquid interface to further assist in the destruction of chemical compounds such as phenols and cyanides. Due to the CDU™ ability to effectively mix and disperse the oxidant being used, the microscopic size ozone bubbles are kept in suspension for the life of the ozone. This has proven effective in reducing turbidity by oxidizing dissolved organic matter present in colloidal forms and colours to restore the natural clarity of the effluent.
