(The process https://padlet.com/alastairmjackson/WaterA3/wish/152962174 2017-02-10 02:35:01 UTC https://padlet.com/alastairmjackson/WaterA3/wish/152962174 What are the different chlorine chemicals used in disinfection during water treatment? https://padlet.com/alastairmjackson/WaterA3/wish/152962188 Chlorine chemicals are very effective against bacteria, viruses and fungi that contaminate water. The 4 following chemicals are used most commonly

NaOCl
Due to its high pH,  sodium hypochlorite increases waters pH

Advantages - Easy transport and storage, highly effective when correctly used.
 
Disadvantages - Corrosive, precautions should be taken in handling, evaporates/disintegrates upon contact with air, light and high temperatures, Short shelf-life.

Ca(ClO)2
Calcium hypochlorite is more stable than sodium hypochlorite

Advantages - Easy transport and storage, more stable than sodium hypochlorite, does not add sodium to the water, highly effective when correctly used.
 
Disadvantages - low solubility, might cause clogging, the final chlorine concentration in water is dependent on the extent of dissolution achieved.

Cl2
This is chlorine in its pure form, which is a very strong oxidizing and disinfecting agent.

Advantages - highly effective disinfectant. Reduces water pH so additional acidification is not necessary, uniform and rapid dissolution in water.
 
Disadvantages - Requires skill and strictest precautions in handling.

ClO2
A powerful oxidant, effectiveness of disinfection does not depend on pH or organic load in the water

Advantages - A powerful oxidant, effectiveness of disinfection does not depend on pH or organic load in the water, no byproducts (such as chloramines) are formed, rapid and uniform dissolution in water.
 
Disadvantages - Requires skill, very strict precautions in handling.

A1. Boil the water. Incase your water contains bacteria boil it so that it will kill the bacteria inside it and you wont be sick

A2. Form a cone out of a strip of bark. according to http://www.wikihow.com/Purify-Water this second method will not fully purify water but it will reduce the amount of microbes in it.

A3. The sun method. This method also relies on the sun and the air but if the place you live has lot's of sunny weather and clean air this method will purify water. In this method you have to put a bowl of water in a place the sun can effect it because eventually the water will evaporate and leave the particles behind.

A4. Also you can put a bowl and put a cup in the bowl then fill it with dirty water. Then wrap the bowl you that when the water tries to evaporate it won't escape causing the dirty particles to go to the top of the bowl and the clean water to stay on the bottom of the bowl.

A5. This method is simple just use a water purifier

A6. You can use a purification tablet which doesn't bring a good taste to your mouth but kills all the bacteria and purifies water really well.
