How does water become clean enough to drink ?
Once water is received from the source it needs to be treated before we can use it. In the previous sections of this module, you learned about microorganisms that need to be filtered out of drinking water. Now well take a look at how a typical water treatment plant purifies our drinking water. The four processes commonly used to treat water are screening, coagulation and settling, filtration, and disinfection.
When water is taken from the source (Like a lake or river), wood, fish, and plants may still be present. These things arescreened out as the water is drawn into the plant. If the source happens to be groundwater, the screening process isnt as vital since the layers of the earth that the water travels through act as a natural screen, removing large contaminants.
When the water reaches the plant it is coagulated and settled. In this process, water is mixed with aluminum sulfate (alum) and chlorine. The alum forms sticky globs, which attract bacteria and other impurities. The chlorine kills germs and improves taste and odor. The water and the globs then flow into a sedimentation basin where the globs “settle” to the bottom and are removed.
Next, the water flows through special filters made of layers of sand and gravel. The gravel layer of the filters is about 1 foot deep and the sand layer is about 2 ½ feet deep! This filtering removes any remaining particles left in the water.
During disinfection, disinfecting chemicals are added and chlorine is used again. This process kills any surviving germs and keeps the water clean over time. In some water treatment systems that use ground water, this is the only method needed to treat the water!
Ever wonder why soap makes your hands clean?
Soap is a very useful substance that allows us to more effectively clean our hands. To understand how soap cleans our hands, you must first understand the chemistry behind water, dirt and grease. Water is a polar molecule. This means that water molecules (hydrogen and 2 oxygen) tend to separate into positive and negative ends. Now some substances, such as dirt and salt, are water soluble. This means they are able to easily dissolve in water, because their molecules have either positively or negatively charged parts (ions) that are attracted to the charges of the polar water molecules (they are hydrophilic). This allows them to become separated in the water and dissolve. Other substances, such as grease and oil, are not water soluble. This means they are not able to dissolve in water because their molecules do not contain positive and negative parts (ions), and so they are not attracted to the water molecules (they are hydrophobic). This means they do not become separated when they come in contact with water, and so they are not able to dissolve in water.
