Various ways in which water under goes in order for it to be treated

Water treatment is any process of making water safe for drinking or water recreation and many other uses, including being safely returned to the environment  and reduces their concentration so that the water becomes fit for its desired end-use. It involves removing of contaminants to produce water that is pure water for human consumption.

The processes involved removing the contaminants include ;

  • Physical processes such as settling and filtration.
  • Chemical processes  such as disinfection and coagulation.
  • Biological processes  such as slow sand filtration.


In biological processes, Slow sand filters may be used where there is sufficient land and space, as the water must be passed very slowly through the filter. filters rely on  their action rather than physical filtration. They are  constructed using graded layers of sand, with the coarsest sand, along with some gravel, at the bottom and finest sand at the top.

 In chemical processing,disinfection After the water has been filtered, a disinfectant may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses which may use of chlorine or chloramine.Disinfection is accomplished both by filtering out harmful micro-organisms and also by adding disinfectant chemicals.

industrial wastewater treatment covers the mechanisms and processes used to treat wastewater that is produced by  industrial or commercial activities. After treatment, the treated industrial wastewater may be reused to a sanitary sewer or to a surface water in the environment.Many industries have a need to treat water so as to obtain very high quality water for demanding purposes. Here are some links where i found my research.

Agnes great job,Anyway water treatment is removing of contaminants,also i understand that sticks,stones are part of unwanted material in water treatment.I find that Ion Exchange is the process by which hardness in water is removed. Particles due to the hardness in water and debris are positively charged. When the water runs through Aquino's resin system, which has millions of negative charges, the water which flows past allows for calcium, rock, iron and magnesium to be brushed off and out of the water.With your research i would like to know  more on the following question on water treatment; HOW DOES AN AQUIN WATER TREATMENT SYSTEM REMOVE HARDNESS?HOW MUCH SODIUM WILL BE IN MY AQUION WATER?I find this important for you hope it will help:

Nice time in your research,

Hey Agnes,

What a nice topic and very informative,i think by learning water treatment you can prevent some of waterborne diseases.when i think of water treatment what comes in my mind is, are the chemical treatment cause some disease?

Here are some website;

I am forward on you next research to learn more on water treatment.Good luck.
