How Does Water Treatment Using Filtration Work?

Sep 29, 2022

Clean, safe tap water to wash and drink is among our most valuable resources. Suppose you’ve wondered what your water source is. In that case, we describe how water treatment works and why water filtering is an essential component of the process.

The process of water treatment filtration is an elaborate process that eliminates dirt and contaminants from the water before being disinfected and piped back to the home. Most water treatment plants employ an approach similar to the one listed below.

What’s the Objective of Water Filtration Treatment?

Have you ever considered the numerous advantages of drinking water beyond staying hydrated? Water has several health benefits for your body, from digestion to skin care.

Before water gets piped into homes and companies, it passes through a meticulously controlled process involving several filtering levels. The EPA provides 90 chemicals that they contain within the drinking water. Water filtration can remove these hazardous or even fatal contaminants so that the public and you can generally reap the benefits of drinking clean water without becoming sick.

How Do Water Treatment Plants Work?

Here’s a brief overview of how the water treatment process operates at most municipal water treatment facilities.

Coagulation and Flocculation

With a holding tank, the filtration process gets started. Positively charged materials get combined with water. They attach positively charged particles, such as dirt, forming floc, a heavier, new particle called floc. It is also known as coagulation or flocculation.


Larger floc particles sink to the tank’s base and away. This clear, pristine water at the top is ready to transfer to the next phase.


Water gets circulated through various filters with smaller pore sizes. Each filter can remove more dissolving particles that remain inside the water. The filters are composed of grit, such as gravel, sand, and charcoal. They are highly effective and can remove harmful elements. They comprise:

  • Dust
  • Parasites
  • Bacteria
  • Viruses
  • Chemicals


After the water is adequately filtered, it gets cleaned. In this last stage of purification, chemicals such as ammonia or chlorine add to water to eliminate any remaining parasites, bacteria, or viruses. The water is also protected while it travels along the underground pipe network until it reaches your home. Although not frequently employed, it can also use UV light to sterilize water.

Sometimes, treatment facilities include a de-chlorination process following the disinfection stage to lower levels of chlorine found in public water.

If My Water Has Already Been Filtrated, Do I Need an At-Home Water Filter? 

In all likelihood, it is healthy to drink. However, some situations periodically shake people’s trust in water utilities.

A water filter for your home adds an extra layer of security and guarantees that the water you drink with your family is completely safe. You can be sure that every sip of water you drink is as safe and clean as it can be when you install a filtration system in your home’s plumbing. The water filter will eliminate excessive chemicals from the process of treatment. It will ensure that it’s safe if the water treatment facility fails. If you have doubts about the chemicals in your drinking water, a filter could provide tranquility.
