Bottled Water Research Paper
WATER
1. Nearly 80% of the surface of earth is water. 2. 97% of all water on earth is sea water. 3. Chemically, it us 2 atoms of Hydrogen and 1 atom of oxygen. We and Water :
1. The human body is made up of about 70% water. 2. Every system in our body needs water. 3. Water makes up 83% of our blood. 4. Water helps us digest food. 5. Water transports body wastes. 6. Water keeps our temperature correct. 7. Each day we must replace 2.4 ltrs. of water. Drinking replaces only a part of it.
The rest of the water is taken by the body from food.
Water Treatment Plant
Follow a drop of water from the source through the treatment process. Water may be treated differently in different communities …show more content…
Bottled water can have minimal (or no) processing - as in natural spring or mineral water, or it can be completely filtered and demineralized to nearly pure water and then have minerals added back in to make it taste better.
The advantages of Bottled Water include:
An emergency source of water in the event your primary water source fails or becomes contaminated. A convenient source of usually safe water for drinking outside of the home. Bottled water, since it does not contain chlorine, and may contain a mix of minerals to enhance flavor, may taste better than untreated tap water. Most bottled water will contain fewer contaminants than untreated tap water.
DISINFECTION METHODS :
Chlorination
1. Contact time reqired is 30-50 minutes. So cannot be used in online system. 2. Residual chlorine may give rise to trihalomethanes. Which are carcinogenic and may affect liver and kidneys. 3. May give rise to a bad smell and odour to …show more content…
Ultra Violet light of the UV-C spectrum destroys the DNA structure of bacteria and viruses. 2. The most widely used UV lamps for water disifection is a low-pressure inert gas djscharge tube loaded with mercury vapour are stimulated by the effect of the electric current and generate the charectersitic spectrum. Activated Alumina:
Activated Alumina is a granulated form of aluminum oxide. In this process, water containing the contaminant is passed through a cartridge or canister of activated alumina which adsorbs the contaminant. The cartridge of activated alumina must be replaced periodically. Activated alumina devices can accumulate bacteria, so treated water may have higher bacteria counts than raw water.
The advantages of Activated Alumina filters include: 1. An effective way to reduce levels of fluoride, arsenic, and selenium
The disadvantages of Activated Alumina filters include: 1. The use of other treatment methods would be necessary to reduce levels of other contaminants of health concern.
