!±8± Water purification process and the declaration of water treatment

The American public water treatment process, but has all the epidemics such as cholera, typhoid and other water-borne diseases over. It can be difficult to explain water purification. And 'no longer a problem for the high school class size to an article written as visual aids are often easier to understand. But we will try to cover some basic facts to help you understand where you fit in

There are differences in process water treatment for the various programsStructures, depending on the quality of the source, there is a lake or a river, and environmental factors and pollutants found in the area. But it is the easiest way to explain, water treatment, as a series of "stages", each with a specific purpose.

The first step is a filter wire mesh, which prevents large objects from entering the tank installation. Things like the fish, the limbs and leaves are left here. The fabric should be cleaned regularly to maintain a constantflow.

As a general rule, then a coagulant is added, which stick together and cause dirt particles sink to the bottom of the tank, making them easier to remove. Because the process water treatment continues, a variety of chemical treatments are used.

For example, calcium binds with certain impurities, so that they can be filtered. Chlorine is often added at this point, to serve as a disinfectant. Today it is not wise to try to explain water purification, not to mention the benefitsAdvantages and disadvantages of chlorination.

In short, chemicals such as chlorine are added to kill bacteria and other organisms. In case of emergency such as a hurricane or other interruption of the service follows, chlorine bleach can be used for domestic use, to clarify and disinfect water suspected. This is a fairly effective disinfectant, are just some microbes resistant to this stage of the process water treatment.

The most obvious disadvantage of this method involves the disinfection and tasteSmell. Activated carbon filters in the house able to remove the remaining chemicals and improve taste, are at the same time reducing the smell. Other disadvantages are not to be attributed to many years or to other causes. Studies have shown that drinking too many chronic health problems and life-threatening today's chlorinated water have to do. But back to our attempt to explain water purification.

The water purification process that usually follows the chemical disinfection is the sandFiltration. It works to remove some of the smallest particles of sand and killed organisms during disinfection. Depending on the environment, there may be additional steps in the process of water treatment, but even here, there is usually tested and stored for the consumer.

The test is performed to determine if there are dangerous levels of pesticides, herbicides, heavy metals, disinfection or chlorine itself. The "safe" are set by the Environmental ProtectionAgency, but are not really for everyone. When you explain water purification, you must remember that the system is not infallible, and neither the subsequent examination. What can you do?

In order to protect ground water, avoid the use of pesticides and other synthetic chemicals around the house. Never dump hazardous materials into drains or on the outside ground.

To protect your family from faulty evidence, dirt and chlorine is harmful impacton their health, you should have an "end user" or home filtration system. This will complete the last step of the process water treatment.
