Ozone is an unstable gas comprising of three oxygen atoms, the gas will readily degrade back to oxygen, and during this transition a free oxygen atom, or free radical is form. The free oxygen radical is highly reactive and short lived, under normal conditions it will only survive for milliseconds.
Ozonation Process
The formation of oxygen into ozone occurs with the use of energy. This process is carried out by an electric discharge field as in the CD-type ozone generators (corona discharge simulation of the lightning), or by ultraviolet radiation as in UV-type ozone generators (simulation of the ultraviolet rays from the sun). In addition to these commercial methods, ozone may also be made through electrolytic and chemical reactions. In general, an ozonation system includes passing dry, clean air through a high voltage electric discharge, i.e., corona discharge, which creates and ozone concentration of approximately 1% or 10,000 mg/L. In treating small quantities of waste, the UV ozonators are the most common, while large-scale systems use either corona discharge or other bulk ozone-producing methods.
The raw water is then passed through a venturi throat which creates a vacuum and pulls the ozone gas into the water or the air is then bubbled up through the water being treated. Since the ozone will react with metals to create insoluble metal oxides, post filtration is required.
Water-tank self-cleaning ozone water disinfector
Operating Principle
First, place the circulation tank of self-cleaning sterilizer to the lower middle part of the water tank so as to guarantee the even circulation of the tank water. When the water level reaches the designed top limit, the electric control cabinet starts up the high-voltage power and the strongly-oxidized gas generated by the immersible pump flows through the pipeline to the aeration section to aerate-disinfect the water, and at the same time, the immersible pump sends the disinfected water back into the water tank to circulate the stagnant water. Thus water circulation continues until thorough disinfection is completed and the water quality is guaranteed. Before delivered off the factory, the time for this product has been setted,no need resetting for the user.

1. Water-tank ozone self-cleaning disinfector
2. Water-tank micro-electrolysis self-cleaning disinfector
Working principle for the water-tank micro-electrolysis self-cleaning disinfector:
The water-tank self-cleaning disinfector starts up electro-chemical reaction to excite the chlorine ions dissolved into the water to generate the following oxidized substances: HCLO, CLO2, O3, O and Cl2, etc. The above oxidized matters will then be diffused and circulated so as to dispose the water tank, all the water inside and the water tank walls, damage the bacteria and alga microbiological cells and ultimately achieve the goal of disinfection and killing algae.
