System and method for water disinfection

A system for liquid disinfection, comprising:

• one or more pipes through which a liquid contaminated by microorganisms is supplied to a cavitation pump;
• a gas generator configured to generate a gas mixture comprising a plurality of gases and to pump the gas mixture into one or more of the pipes, wherein the gas mixture mixes with the liquid within one or more of the pipes;
• a cavitation pump configured to provide cavitation by an impeller of the pump under a pressure of substantially 0.0981 MPa-5.394 MPa and to cause a formation in the liquid of ultra-fine bubbles via the impeller slicing larger bubbles into the ultra-fine bubbles, to dissolve a portion of the gas mixture within the liquid via the cavitation, and to pump the liquid, the ultra-fine bubbles within the liquid, and the remaining undissolved gas mixture into a line atomizer;
• and
• the line atomizer configured to dissolve a further portion of the gas mixture into the liquid by churning and mixing the liquid, the ultra-fine bubbles, and the gas mixture under the pressure of substantially 0.0981 MPa-5.394 MPa, wherein the dissolved gases reduce a concentration of microorganisms within the liquid.
