What is ozone layer and what are its advantages?
The major function of the ozone layer is to stop the harmful radiations coming from the sun as well as from stars. Ozone captures those radiations which are of low wavelength. It also stops the harmful ultraviolet rays. These radiations are very harmful for living beings.
What is the disadvantage of ozone?
Ozone is very reactive and corrosive, thus requiring corrosion-resistant material, such as stainless steel. Ozonation is not economical for poor quality (poorly treated) wastewater. Ozone is extremely irritating and possibly toxic, so off-gases from the contactor must be destroyed to prevent worker exposure.
What is the main function of the ozone layer?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
What are 3 disadvantages of using ozone to treat water?
Ozone Water Treatment Disadvantages
- Solubility and Activity. If the dose of ozone is too low, some of the germs and especially those that can form cysts may survive.
- Reactivity. Ozone’s reactivity is what makes it such a great disinfectant.
- Expense.
- Residuals and Byproducts.
What is the advantage of using ozone instead of chlorine as disinfectant?
Ozone is now used as an oxidant and disinfectant in water treatment plants worldwide. Ozone is extremely faster and more powerful than chlorine in removing organic and inorganic matter, bacteria, viruses, pesticides, turbidity, odour, taste and color from potable water production.
How can students protect the ozone layer?
How can we protect the ozone layer?
- Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process.
- Minimize the use of cars.
- Do not use cleaning products that are harmful to the environment and to us.
- Buy local products.
Is ozone good for us?
Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
