SOZ-HS ozone generators for brackish water These models can be used for disinfection or oxidation for high salinity/brackish water. Because ozone is a strong oxidizing agent, it can be effectively used for bleaching, color and odor control, disinfection, reducing ammonia concentration, oxidation of organic matter or toxic compounds, and many other applications. Conventional disinfectants, like chlorine, leave residuals in the water and can cause the formation of DBPs, which is not always desirable in environmentally sensitive areas and industries. On the other hand, ozone quickly degrades to oxygen, leaving no trace in the effluent. That is why it’s widely used in agriculture, hydroponics, fisheries, and sewage treatment prior to discharging into surface water.

Working principle: System consists of oxygen generator, ozone generator, highvoltage power supply,

air dryer, control panel, and other

components. Built-in oxygen concentrator with zeolite media imported from the US provides an excellent source of oxygen for ozone generator. Equipment is based on the latest modern technologies and innovations. Rational design ensures stable operation and high output. Automatic pressure control and air-storage tank protect

Portable water ozonator Overview This device can be used for water disinfection with ozone. It kills bacteria, viruses, and other pathogens, producing safe and clean water.

Ozone injection systems There are two key components needed for effective ozone disinfection. First is the ozone generator, providing stable and reliable ozone flowrate. Second element is the mixing system or injection system. Effective mixing is required to ensure sufficient ozone concentration in the water, needed to kill pathogens or oxidize harmful compounds. It is vitally important to have highly efficient injection system, otherwise the capacity of your ozone generator will not be used completely and target disinfection goal might not be achieved.

Mixing methods Operating instructions

3) Set up the timer choosing from 5, 10 or 15 minutes treatment time;

1) Bubble diffuser Principle - counter current, cocurrent or both contactor design. Continuous or intermittent operation. Advantages: low power consumption, no moving parts, simple operation, good zone transfer rates. Disadvantages: fouling of the diffusing pores, deep contact basin, additional air compressor.

4) Turn on the power switch to start the device;

2) Venturi injector

5) The device will automatically stop when the disinfection is over;

Principle - negative pressure injection through a conical device. High pressure pump us often used for the sidestream to increase pressure difference. Advantages: no moving parts, high ozone transfer rates, compact size. Disadvantages: higher energy usage, complex operation and high cost. Our Venturi injectors are made of a strong PVDF plastic to ensure long service life and reliable operation.

1) Preparation: check the connections, clean outlet ports and airstone if needed; 2) Put the dispersion stone into the water;

6) Unplug the connection piping; put everything inside and close the box.

Hybrid mixing system design is shown on the diagram below. System consist of 3) Jet mixing chamber (SLW) Principle - combines the efficiency of vacuum venturi injector with simplicity of static mixers. Injector is used to add ozone to the water, then static mixers further split gas bubbles to increase the contact area and to improve mixing efficiency. Allows achieving more than 90% ozone transfer efficiency. When combined with high-capacity SOZ-6G ozone generator, can achieve more than 0.8 - 1.0 mg/L ozone concentrations. For SLW systems we use only ozone resistant materials: main chamber is made of 304/316 stainless steel, other parts, including inner components are made of PVDF or ABS. This approach increases system life time and minimizes the maintenance.

AOW - automatic air dryer Ambient air always contains a certain amount of water and dust particles in it. In humid and/or polluted regions, this gets even more important. After passing through the high-pressure compressor it also becomes polluted with oil mist. Such an air will lower the efficiency of ozone generation, and significantly reduce system service life. To avoid these risks, air dryer can be used to obtain a high-quality pure air. Our AOW series air dryers use a zeolite bed to adsorb water and oil, and to filter out small dust particles. Automatic discharge system provide hassle-free cleaning of the system and ensures stable and reliable operation.
