Water Treatment: Vital for Human Survival

Only in fresh water in lakes, rivers and may reach ground water for human consumption to be used, but not all of these sources are still safe due to the fact that it could result in higher concentrations could be microbes in these sources , so some diseases of the digestive system as hepatitis and cholera. Not only that industrial / agricultural waste pesticide residue how to make the water unsafe because of its toxicity , the proliferation of various side effects such as skin irritation , bone disease , among many other beverage. With all these factors into consideration , the people have a great need for drinking water. Therefore, the treatment of water is essential to safe drinking water to 100 % to ensure for all .

 

Water treatment is the process of reducing ( or , if possible, eliminate ) the harmful substances in the water and the addition of certain chemicals that the cleanliness during its distribution would ensure . Facilities for public water supply treatment often surface water sources such as lakes or rivers and through six key steps to make it drinkable. These steps are : Screening ( removing large debris from the water ) Sedimentation (removal of small particles , such as sand and dirt) , precipitation (removal of molecules / ions side) , filtration (to remove small particles have failed to remove sediment ) adsorption ( removal of organic compounds with activated carbon in powder form or CAP) and disinfection ( elimination of microorganisms in the administration of certain chemicals such as chlorine and chloramine ) .

 

As mentioned above, the method of the water treatment contains not only the removal of potentially harmful substances in the water. This process also supports adding some useful substances that act beneficial in different ways. For example, fluoride is regularly treated to the teeth to all the strong drinks water . Proper administration of fluoride in water reduces cavities in children (and adults ) in many cities around the world .

 

Finally, the process water is a cycle , once the water has been used , there are two ways to recover the supply of fresh water by natural evaporation (an example is the human sweat, which eventually evaporates rain ) or agencies for dealing with waste water ( otherwise known as sewage treatment plants ) .

 

The process of wastewater treatment used almost the same processing steps of the water , but his goal is the treated water into the center once it is . Considered safe enough especially in the case of lakes / rivers where swimming and fishing occurs

 

In essence, the constant supply of clean drinking water is of the utmost importance , which is why water treatment is essential to meet this demand. Also to ensure that contaminated water remains until it reaches homes , good internal plumbing is a must.
