The procedure of recycling of water is a process that mystifies most of the average consumers. Many wonder just what is done to water that is dirty and polluted that can make it safe to be consumed or used again, after it has been used once already. The detailed procedure of recycling of water is a bit complicated, but the process takes place within a few steps that can be easily understood.
The first step in the procedure of recycling of water is the screening of the water. Once the water comes through the sewer system, any large objects will be filtered from the water. This is done using bar screens in most places. The water must also be clarified, before any other treatment begins. This is done by slowing the movement f the water through the system so that any small particles can settle to the bottom and fatty materials can rise to the top for removal.
Next, the procedure of recycling of water calls for the use of microorganisms to break down other materials that might be suspended in the water. The water will be aerated during this step to help the microorganisms to thrive. These microorganisms will consume the materials, then turn them into solids that will settle to the bottom. These solids can then be removed from the water, prior to the next step in the process. The water will then go through another clarification process in which these solids are removed, along with the majority of the microorganisms.
The final step in the procedure of recycling of water is the chlorination of the water. Chlorine will be added to the water to kill any leftover microorganisms that were not removed during clarification. The chlorine may then be removed by using sulfur dioxide, prior to returning the water to the ecosystem. This is done to keep marine wildlife from being harmed by the chlorine.
There have been same improvements to the procedure of recycling of water, in recent years. There has been a movement toward using ultraviolet radiation to replace the chlorination step. This provides an even safer final product to be released into the environment. While this is not yet widespread, many newer water recycling plants are using this technology.
This is just a basic overview of the procedure of recycling of water. The details may vary depending on the geographical area and the recycling plant, itself. While the process is complex, with many steps, this has been proven to be the most effective way for recycling waste water and returning it to the ecosystem to go back through the atmosphere and be reused safely at a later time.
