How to kill the bacteria present in water by bleaching powder method ? 

The normal water may be contimaneted by many harmfull bacteric which is not good for our health also it may affect oue health at very serious level 

So for the consumption of water it is required to make the drinking water free from all kinds of bacteria so that we can overcome with the harmfull desiease happens with the consumption of contimenated water 

So today we will discuss the bleachig powder method as a disinfectant of water 

Bleaching powder which is also known as calcium hypochlorate 

It contains about 30 % available chlorine it reacts with water to produce hypochlorous acid which is a powerfull disinfectant due to its property of liberation of nacent oxygen 

Also it has the potential to sterilize much water at a time around 1 kg of bleaching powder is sufficient to sterilize one million liters of water. 

The necent oxygen which produce in this reaction destroys the pathogens by oxidation the anion of the reaction repture the cell membrane of the paythogenic bacteria present in the water also the chlorine it self has the potential of powerfull anti-microbial activity. 

Disadvantages :- 

Bleaching powder method has a very good potential to strilize a large amount of water at a time but instead of this it has some disadvantages with them which we will be discuss below 

• By the use of bleaching poweder it introduces calcium ion in water which is responsible for the hardness and Ph of the water 

• Excess use of bleaching powder in water produces disagreeable odour and bad taste and cause irritation therefor a calculated amount of bleachin powder is added to the water 

• Due to the continuous decomposition during storage its chlorine content goes on changing. that's why before addition of bleaching powder its chlorine content should be analyze properly 

That's all you need to take care while using the chlorination method for the sterilization of water 

I hope the above mentioned information help to go through the bleaching powder method and helps you to identify the reason of different taste and odour of the water when you consume that kind of water next time 

One thing you should keep remember that the odour and taste of water may be affected by many other reasons also 

Thankyou
