We are going to be explaining the basics of the science term; separation and our part in it; filtration. We will explain filtration in a little bit, but we will give you the brief details of separation. Separation is a term that means the parting of two different atoms or particles. Think of it as when water escapes ice, the water is separating.
Definition: The process of removing something unwanted from a liquid such as water using a filter.
As you can see, the water particles are moving from the ice particles. This is called separation. That is just a brief description of separation.
Filtration and Its Process
(In a Water Treatment Plant)
1. Coagulation/Flocculation – This process is where liquid aluminium sulfate and polymer are added to the water.
2. Sedimentation – This stage uses gravity to pull any impurities to the bottom of the sedimentation basins carrying the water.
3. Filtration – This is the process of separating the particles from the original substance. When you filtrate, the particles change.
4. Disinfection – Chlorine is added to the water to remove any dangerous bacteria or viruses.
5. Sludge Drying – Sludge drying is the process of moving the now separated particles and drying them to see the purified particles.
6. pH Correction – This stage adjusts the pH level to prevent erosion in the distribution centre.
Real World Applications
This is a simple home-made version of a filter. Each material catches any impurities like the rocks catch larger impurities, and the fine sand finds microscopic impurities.
This displays how the kidneys remove any waste material from our blood, essentially being our body’s own filtration device.
Facts You Didn’t Know!
– One of the earliest recorded methods of filtration was by using a filter made out of charcoal or sand
– Chlorine is a chemical first used by an English physician named John Snow.
– It was first put into Londons drinking water supply in the mid 19th century, to help combat cholera outbreaks that ravaged the citizens of London
– The U.S. uses 77% of freshwater in the world
– 8 million people die annually from drinking unsanitary water
In conclusion, we need filters for everyday use. Without ’em, we would have no coffee. Without ’em, we would have no safe drinking water. And without ’em, the human race would not survive for very long!
