What are the different types of water treatment?
by its very nature is always pure, because the binding between the atoms of hydrogen and oxygen is extremely strong. The problem is that almost all the world's water supply must share space with organic material, chemicals, minerals and pollutants. The result is often a non -duty solution, probably containing deadly bacteria, viruses and other diseases. Fortunately, humanity has developed a number of water treatment methods that make our water supply much safer for consumption. Not all of these water treatment methods work on a large scale, but all cause people are not treated untreated water. The untreated water collected from the natural source can be undisturbed in the container, allowing a fixed device to settle from the solution and fall to the bottom. After enough time, the highest water level can be pulled out for consumption.
This water treatment has several main disadvantages. The settling process may take several days or weeks to be effective and there is no requestProtection against bacteria or other organic materials that may not deal with. If the water source is relatively clean, for example, a mountain stream in a remote area, the water deposit method may be adequate.
A more thorough and faster form of water treatment is a boiling method. The water should first be filtered by a substance to remove larger contaminants and then placed in a clean metal container. Virtually every bacterium or other dangerous forms of life will not survive the boiling process, although experts suggest boiling boiling for a few minutes to ensure success.
As soon as the water cools down, it should be safer to drink. One disadvantage method of boiling water treatment is the possibility that the inorganic solids of May still remain. Cooking a large amount of water can also be very time consuming.
One form of water treatment that works on a large scale is chemical disinfection. WatersAnd it can be drinking, if not particularly taste, adding iodine or chlorine tablets. Chemicals destroy many bacteria and other organic contaminants found in natural water supply. Pills with water treatment carried by tourists and campers usually contain a form of iodine, although some people with iodine allergies can use chlorine -based tablets. The treatment of chemical water is also a preferred method of pool operators because chlorine kills a number of contaminants brought through faecal matter.
For homeowners who were afraid of their public water reserves, another form of water treatment was more and more popular. Filtration through activated coal or paper filters is a low -cost water treatment method used in many private houses. The water supply flows through a small filter at the end of the faucet or a more sophisticated system in the basement or kitchen.
The principle of the filter method is that heavy metals, organic contaminants and many bacteria are simply too big to do itto go through the filter network. The water molecules that pass are much cleaner and provide a better tasting product. However, the filters must be changed regularly to be effective. Bacteria can grow on filters clogged with organic material.
For those who may want an even more discriminatory water treatment method, there is reverse osmosis. Many water treatment companies and bottled water manufacturers use reverse osmosis along with other methods such as filtration or ozonation. Reverse osmosis requires the use of semi -permeable material with extremely small holes. The untreated water is forced by this membrane that prevents the smallest forms of bacteria and chemical pollutants in the passage. The tsamote water molecules actually change to pass through the membrane. The resulting water supply is said to be "wetter" because the individual water molecules have fewer sides and are more easily absorbed by the body.
Other forms of water treatment may include ozonation, ionization and ultra exposureAfial light. The treatment of ultraviolet light will destroy the DNA of all harmful bacteria present in the water, but the costs of installation and operating such a system of water treatment in the house can be unbearable.
