Ozonation of Drainage water for Drinking and Gardening

Ozonation of Drainage water for Drinking and Farming

 

What is ozone?

 

Ozone (O3), also known as activated oxygen contains three atoms of oxygen rather than the two atoms we normally breathe .Ozone is the best of nature's tools for cleaning the air, a unique and natural phenomenon that helps us in many ways. The ozone layer around the Earth protects us from the harmful UV rays of the Sun. The ozone in our atmosphere also helps clean the air and reduce pollution, and it works actively to create a much healthier environment to work and live in. Ozone is one of the most powerful sterilisers in the world that can be used to destroy bacteria and virus. When bacteria or viruses make contact with ozone, they are destroyed completely by oxidation hence ozone is a colourless gas with powerful oxidizing properties.

 

What is Ozonation?

 

Ozonation is the process of passing impure water through a tube that injects ozone gas (O3) into it and thus sterilizes it and render it fit for drinking. Ozonation is widely used in most parts of Europe and Asia due to its ability to kill bacteria and a greater and more effective scale than Chlorine. Ozonation removes metal oxides found in water such as iron and manganese which are a major cause of water stains and in extreme cases pungent smells. These impurities are then disposed of and the clean purified water is returned into the water supply system.

 

How is ozone produced?

 

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis, If a freed atom collides with another O2, it joins up, forming ozone O3.Ozone is also produced as a result of lightning strikes that usually occur during thunderstorms. Ozone can also be produced artificially, There are basically two methods of producing ozone...ultra-violet and corona discharge. Corona discharge creates ozone by applying high voltage to a metallic grid sandwiched between two dielectrics. The high voltage jumps through the dielectric to a grounded screen and in the process, creates ozone from oxygen present in the chamber. Ultra-violet (UV) light creates ozone when a wavelength at 254 nm (nanometres) hits an oxygen atom. The molecule (O2) splits into two atoms (O), which combine with another oxygen molecule (O2) to form ozone (O3).

 

Why Ozonise?

 

People over-look the fact that these impurities are essential for plant growth and soil structure improvement. Ozonation would create a platform that will allow a portion of drained water to be completely purified and returned to the consumer supply system for drinking and another portion of it to be moved to a mixing tank for minor filtration before being returned to consumer to be used ONLY for gardening. This water will be rich in minerals essential for healthy plant growth allowing consumers to have the benefit of receiving clean drinking water whilst at the same time having a separate water source for their plants.

 

What’s the cost?

 

While setup might be a bit costly due to the need for professionals to see to it that the Ozonation process is carried out safely, on a larger scale it is very cost efficient. Most families avoid having too many plants at home or rather a garden due to the painful rise watering plants puts on the water bill. Using such a purification system will mean there will be a way cheaper water source to be used for gardening. This will promote farming and provide families with food and self-employment opportunities. Aspiring students will have a new interesting course they can venture whilst being guarantee employment in their countries because the jobs have been made available.

 

Quality of drinking water

 

Rain water in most situations is said to be the purest and the smell in the air after a thunderstorm the most refreshing. All of this is caused by Ozonation of atmospheric water vapour by lightening. Imagine this experience being brought right to your home. Ozonation removes a large number of metal oxides and this making water that has gone Ozonation and filtration very pure and (although water is tasteless) tasty to drink.
