How a Water Treatment Plant Works?

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 a Water Treatment Plant Works?

A water treatment plant is an essential part of many cities and towns, ensuring that the public has access to clean, safe drinking water. The process of treating water involves a variety of steps, each of which is designed to remove impurities and contaminants from the water. Understanding the different stages of water treatment can help to understand the process and appreciate the importance of drinking clean water.

The first step in water treatment is coagulation and flocculation. This process begins with the addition of chemicals, such as alum and polymers, to the water. These chemicals act as coagulants, which cause suspended particles in the water to stick together and form clusters, or flocs. As the flocs increase in size, they settle to the bottom of the water tank, which is known as sedimentation.

The settled flocs are then removed from the water by a process called clarification. Clarification involves using sedimentation tanks, which allow the flocs to settle out of the water. A skimmer removes the flocs from the surface of the water, while a scraper removes the flocs from the bottom of the tank. The clarified water is then sent to the next stage of the treatment process.
