Chlorinating Water to Make sure It Is Safe To Drink






     In order for most water to be safe to consume it must be free from infection causing bacteria. One of the classical means of removing this difficulty is by chlorination or the adding of chlorine. The chlorination of potable water systems acts as one way to help disinfect a communities drinking water supply or that of private or public wells.

Ensuring safe water for drinking is an interest for most cities. The disinfection of this vital resource is crucial in decreasing the amount of illnesses that can proliferate through a district, which can bring about sickness and death. Through chlorination and alternative disinfection processes these numbers can be lowered. Many counties impose regulations that expect chlorination of their water supplies as well as other standards be met before this resource can be regarded safe for consumption.

Chlorination is performed by utilizing a few distinct forms of chlorine. It can be a gas, a liquid or a solid. The liquid and solid forms are by and large the easiest to use and the most stable. Liquid bleach is sold for washing clothes but can also be added in minute doses (a few drops) to drinking water to help purify it. Municipalities may use the gas form of chlorine for chlorination which is ordinarily not advisable for personal use.

When chlorine is introduced to H2O it combines with the small particles, animals, microorganisms and other compounds that in essence will use or use up the chlorine. During chlorination it is necessary to have ample chlorine to combine with these microorganisms and also have some chlorine that does not combine or remains free in order to have persistent disinfection. Adding the proper quantity of chlorine makes sure that a good amount of chlorination is maintained for continual disinfection.

A further concern in chlorination is the amount of time the chlorine has to act on the small particles. If they are not combined long enough the chlorine does not have enough time to kill the bacteria. There are several methods used during chlorination, including holding tanks and longer supply coils that can help increase the amount of contact time. Further factors such as temperature and the amount of alkalinity in the water can also alter the chlorination time.

If there is not enough time for the particles to combine an alternate is to use super-chlorination which adds approximately ten times the amount of chlorine to the supply. This would be followed by a reverse chlorination procedure that uses carbon filters to eradicate excess chlorine. Shock chlorination is an one time process that can be used when springs are new or have been refurbished, or when a borehole has been contaminated.

Chlorine levels in mains supplies should be monitored to prevent over chlorination. Too much chlorine could be hazardous or can leave a nasty taste to water, although not enough may not kill all the bacteria. The right level of chlorine in chlorination is essential for maintaining reserves that are safe to drink and that taste pleasing.

Chlorination of drinking water systems has helped solve the problem of having a drinking supply that is safe. When used in the right measurements for the proper amount of time chlorination can eradicate harmful microorganisms that lead to sickness and infection. Many deaths have been avoided and much ailment has been averted through the introduction of chlorination to water.
