Water treatment plants can use a process called ultrafiltration in addition to or instead of traditional filtration. During ultrafiltration, the water goes through a filter membrane with very small pores. This filter only lets through water and other small molecules (such as salts and tiny, charged molecules).
How Do Water Treatment Plants Work?
Water treatment plants are essential for providing safe and clean drinking water in communities. These plants use various processes to remove unwanted substances, like bacteria, sediment, and minerals, from water sources.
This process helps to protect the public’s health and keep our environment clean. In this article, we will discuss how water treatment plants work.
Water treatment plants begin by taking in water from a variety of sources, such as rivers, lakes, wells, and aquifers. The water is then filtered to remove large particles like sediment, leaves, and other debris.
This is often done through a process called sedimentation, which uses gravity to separate the particles from the water.
The next step is coagulation and flocculation, which involve adding chemicals to the water to bind together smaller particles. This causes them to form larger clusters called “flocs” which are easier to filter out.
After this, the water is sent through a series of sand filters, which trap even smaller particles. The water is then treated with chlorine, ozone, or ultraviolet light to kill any bacteria.
Chlorine is the most commonly used disinfectant, as it is effective at killing bacteria and viruses and relatively inexpensive. Ozone and UV
