Application of ozone generator in sewage sludge:

The importance of wastewater treatment has become more pronounced in the past century due to population growth and greater need for water resources as well as wastewater treatment and disinfection. (Pathogens) It is considered to be used to prevent the spread of waterborne diseases in the environment. Ozone in wastewater treatment uses new methods of disinfection that are superior to previous methods of wastewater chlorination. Ozone is a very powerful oxidizing agent that passes through high-voltage alternating current between 6 and 20 kW through oxygen. The electrode, which is separated by a non-conducting dielectric and discharged immediately, is produced, ozone being produced at the same site because it is highly unstable and decomposes within seconds after production.

Features of a disinfectant:

Disinfectant should not remove toxic residues (such as carcinogens) after disinfection.
Have the power to infiltrate and destroy infectious agents under normal circumstances.
Not harmful to humans and the environment.
It is safe and sound and easy to maintain and transport.
Cost-effective with practical and applied costs.

Depending on the characteristics of a good disinfectant, the mechanism of ozone disinfection involves the following steps:

1. Direct oxidation or destruction of the cell wall so that the cell components leak out.

2. Preparation of the inlet gas of the system or the feed gas

3. Ozone Caller

4. Mechanism of elimination of excess ozone

5. Damage to nucleus or nucleic acid (DNA, RNA)

6. Cell reaction with radicals released from ozone decomposition.

7. Depolymerization reaction breakdown of carbon-nitrogen bonds.

Benefits of using ozone (ozone generator) in wastewater treatment:

- Ozone is produced and consumed at the project site, so ozone does not actually cost to transport and maintain.

-Azen is a powerful and effective disinfectant with higher oxidizing power than chlorine (3000 times), chlorine dioxide, chloroamines and hydroxyl radicals.

- All wastewater contains parasitic vesicles that cause pathogenicity, the size of these microscopic particles being too small to be visible to the naked eye, which causes ozonation to kill all parasitic cysts.

- After ozonation, the amount of coagulants used decreases, which in turn increases the speed and quality of the filtration process.

- Organic micro-contaminants are found in the effluent alongside the organic matter, but their concentration is much lower (about 0.1mg / L to 100mg / L), which is partially depleted by OH ozone.

In general, types of wastewater, both domestic, industrial and hospital, can be treated by ozonation. The operating conditions and dosage used for ozonation depend on the type of wastewater and the type of industry.

Based on this finding, new types of microorganisms, such as parasitic eggs and worms, are emerging, and more types of contaminants appear. Increasing the quality level required for wastewater and wastewater has led experts to pay particular attention to the ozonation process.

The use of ozone generators for the treatment of drinking water and various industrial and urban wastewater is increasing day by day. Due to its advantages, ozonation has been able to replace conventional purification processes in many cases such as disinfection and oxidation of organic compounds. This new process has increased the efficiency of the old purification methods in many other cases, such as suspended solids.

The processes carried out by the research department focused on the wastewater of the food processing plants and the water obtained from the washing of the relevant lines. The results indicated a reduction in the microbial load of the odor aftertreatment, in addition, this set of effective measures to replace The old ways have come with this new technology and have achieved interesting and desirable results.
