How Gases Help Produce Clean Water

How Gas Is Used for Water Purification

May is National Water Safety Month, making it the perfect time to learn the importance of proper water safety and how industrial gases can make water treatment processes more efficient and viable.

Having safe water means using a treatment plant to process and purify wastewater into something potable. It’s a complicated process with many alternatives, but it’s essential. Let’s explore the topic one step at a time.

How To Create Clean Water and Why Fresh Water Matters

There’s more to water purification than drinking water. Controlling water quality involves lakes, streams, wastewater, stormwater, natural disasters, and much more. Protecting the water supply is a water treatment plant’s fundamental purpose. Water agencies constantly monitor and ensure water quality with tests, benchmarks, and various purification methods.

Contaminated water contains fungus, minerals, metals, bacteria, and other substances that make people sick if untreated. Water agencies remove pollutants through a detailed mechanical and chemical process. The water treatment process has several basic steps:


The treatment plant filters chemical compounds into the water traveling through the facility to remove dirt particles and other substances. The chemicals act as a magnet, attracting the particles in the water.


The captured particles sink to the bottom of the sedimentation tank and remain there, allowing the treated water to advance to the next stage.


The filtration process further purifies the water. Filtration is a biological process that runs water through tanks to capture charcoal, gravel, sand, bacteria, and other particles. These purification methods are chemical-free to prevent side effects.


Chlorine is applied to kill any lingering microorganisms. By the end, you have a full supply of purified water.


The treated water is released into the pipes that run through businesses and households.

Alternative Water Purification Methods

Oxygen and carbon dioxide are essential components in water treatment. These elements help purify wastewater, drinking water, and the water from lakes and streams. New carbon dioxide water treatment strategies eliminate contaminants that most traditional methods can’t address completely.

The CO2 Purification Process

Some water treatment plants substitute carbon dioxide for chlorine during the disinfection phase of the water purification process. Carbon dioxide does a better job of cleaning water and is less expensive than the sedimentation, filtration, and disinfection stages of the basic treatment procedure.

In this purification method, carbon dioxide is dissolved in water, charging and separating impurities from the clean water supply. The chemical gradient the process creates helps filter out 99.9% of all pollutants and contaminants. The CO2 purification process is energy efficient and easily replicated. Treatment plants concerned about water purification costs should consider a CO2 alternative.

The Oxygen Water Purification Method

High-purity oxygen is used in the aeration process, a water purification method that provides the same benefits as a chemical process without adding chemicals to the clean water supply.

Bacteria break down wastewater pollutants into CO2 and water. Bacteria alone take too long to develop and remove organic matter. If left in a water tank, they produce hydrogen sulfide, which eventually becomes methane. Oxygen introduced during the coagulation phase helps bacteria multiply.

The bacteria created by aeration consume animal residue, soils, sand, gravel, and more. Once completed, the particles sink to the bottom of the sedimentation tank, and the clean water passes through. Together with the CO2 purification process, aeration is an effective alternative to traditional water treatment procedures. Both introduce cost and process efficiencies, providing safe water for people to consume.
