Water Treatment Plant operators have a critical role to play in our daily life as water is one of the most essential basic elements to life on earth. The other one is air. We drink water to survive. Almost 2/3rd of our planet is covered with water making it the only living planet in the entire universe till date. That is why it is called the blue planet. Explorations are being made to the Moon and Mars in search of water so one day we can colonize them.

Before the Industrial revolution in all the countries at different points of time, beginning with England, we used to have pure and clean water to drink from lakes and rivers. The rapid industrialization led to the growth of modern cities which are grossly overpopulated and dirty. The lack of sufficient clean water has led to the degradation of life in these cities. The industries have poured millions of tons of pollutants into the water resources like rivers and reservoirs which are lifeline to these cities, making it undrinkable.

The government along with the water treatment plant operators has taken various steps to ensure sufficient and clean water for people in these cities. The creation of water reservoirs and means to deliver drinkable water to the people in their homes is one of the most important tasks undertaken in cities.

This article will help us understand the whole process and the role of water treatment plant operators.

The Water Treatment Plant Process

Water Treatment Plant Operator 2023- Welcome to the Water world

The raw water from the water reservoir is delivered to the head works of the water treatment plants. The operation of the water treatment plant process in power plant consists of five major unit processes to make the water safe for drinking. These five major unit processes are given below.

  1. Chemical Coagulation
  1. Flocculation
  1. Sedimentation
  1. Filtration
  1. Disinfection 

Step 1. Chemical Coagulation

An oxidant Chlorine dioxide that is used to break down organic matter such as decaying leaves and other plant material is added to the raw water. Then a chemical coagulant Aluminium Sulphate is used as a primary coagulant. A polymer is also added to the water as a coagulation aid. These coagulants are added at the rapid mix unit. The coagulants cause very fine particles to clump together into larger particles which can be removed later in the treatment process by settling,skimming,draining and filtering.

Step 2. Flocculation 

The coagulated water then flows to the next major unit process known as Flocculation. This process is a slow process that causes the small, coagulated particles to form floc. The floc formed creates a surface in which the particulates in the water adsorb to the surface of the floc thus forming larger settleable particle for ease off removal by sedimentation and filtration.

Step 3. Sedimentation 

The flocculated water then flows to the next major unit process, the Sedimentation process. This process removes suspended solids or particles that are heavier than water and reduces particulate load on the filters. This process removes ninety percent of the solids in the water. The clearer water on the surface is collected in the launder tubes that direct the water to the filter to remove the remaining ten percent of solids.

Step 4. Disinfection 

The settled water then flows from the Pre-Sedimentation building to the filtration facility after adding chlorine to the water to begin the disinfection process. This process is designed to kill or inactivate most microorganisms in water like bacteria, viruses or intestinal parasites that causes diseases like gastroenteritis, typhoid, cholera etc.

Step 5. Filtration 

Now the water flows into the filtration facility and onto the last of the major unit processes used to treat drinking water.Filtration is the process of passing water through material such as bed of coal, sand or other granular substance to remove impurities that are not removed during sedimentation process.The water treatment plant uses rapid rate multi-media gravity filter beds.When the filters start to get full of particles, the water treatment plant operators clean them using a procedure called backwashing. The backwash water is sent to the backwash recovery pond, and after the settling process, the backwash water is returned to the raw water settling pond for re-use.
