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.

Calibration Gases and How They Increase Workplace Safety

Guide to Calibration Gases

Accurate measurements of industrial gas levels are crucial for maintaining safety in multiple industries. Malfunctioning gas detectors increase the exposure of health hazards to employees and the public. That’s why workers use calibration gases to verify that gas detecting equipment is working properly. Calibration gases are gaseous components used to contain toxic and flammable gases on a jobsite. Read more about the uses of calibration gases and how they increase safety.

What Is a Calibration Gas Used For?

Calibration gases are a mixture of compressed gases or gas components used to test gas detecting equipment to make sure that it’s working correctly. Calibrating equipment is critical for all measuring instruments and establishes a known response to a chemical component. Finding the right calibration gas for your detector depends on a variety of factors, including:

Type of Gas Detector

Understanding the type of gas detector you’re working with plays a significant role in which calibration gas you use. Most single gas detectors use methane or iso-butane calibration gases, while multi-gas detectors use specialty gases composed of four-gas blends and mixed in specific concentrations.

Purity of the Gases

It’s important to ensure the purity of the gases you’re testing. Working with impure gases could alter the detector’s sensitivity and lead to inaccurate results. Referring to the gas standard assures that the gas you’re using is pure.

Quality of Calibration Gas

Making sure you’re using high-quality calibration gas enhances safety. Poor quality gases could ignite, making them a significant health hazard for your staff. Also, don’t use any gas that’s past its expiration date; expired gas could lead to inaccurate readings.

How To Calibrate Your Gas Detector

OSHA recommends frequently calibrating your gas detector to maintain employee safety. Here are three ways to verify calibration gas safety:

Bump Test

A bump test is a qualitative test that involves passing calibration gas over the instrument’s sensor at a concentration greater than the set points to trigger the alarm. This serves as a functional test and should be performed before using any equipment.

Instrument Calibration

An instrument calibration exposes the equipment to a test gas to verify that the sensors and alarms adequately respond to a manufacturers’ preferred guidelines. If the calibration check results don’t fall into an acceptable range, then a full calibration should be performed.

Full Calibration

A full calibration adjusts the instruments’ reading to match the known concentration of the test gas. It’s a quantitative test that confirms the instrument’s sensors are open to flow and operate within a specified tolerance.

An instrument’s sensors degrade over time and repeated use. Regular calibration allows your equipment to reset and lets you know when to order replacement parts.

Product Spotlight: Acetylene

Acetylene is one gas that may be indispensable to industry. It is used for the production of chemicals, plastics, lighting, and it is critical to the fabrication industry as a welding fuel. Acetylene is a versatile gas and one of the key industrial gas products that CK supplies to our commercial partners. 


Pure acetylene is colorless and odorless but with some impurities it can have a distinctive odor. With oxygen, acetylene burns at very high temperatures which makes it invaluable for cutting, texturing, hardening, flame gouging and thermal spraying of many different kinds of materials. 


Acetylene is produced as a chemical reaction between calcium carbide and water which occurs at normal temperatures. Another process called thermal cracking requires high temperatures. Acetylene is very reactive and can be hazardous if combined with other gasses like oxygen. Because of this, it must be stored and handled with absolute care. 

The Industrial Uses of Acetylene

Welding, Cutting, and Heat Treating

Acetylene creates the hottest flame of any welding fuel. High temperatures mean acetylene is perfect to cut metals and heat treat them as part of many industrial processes. Welding equipment that uses acetylene can be very versatile as they do not require electricity. This allows acetylene based equipment to be used in remote locations where an electrical connection is not possible. 


Calcium carbide was once used to light streetlamps and as an early light source for lighthouses as it produced an intense, bright light. Most early automobiles used this form of lighting before electric headlights were commercially available. Since this form of lighting used a highly-reactive substance, most lighting applications of acetylene moved on to safer solutions but calcium carbide is still used in some cases for mining and underground use. 

Chemical production

Acetylene is used in the synthesis of certain vitamins like vitamin A and D. Also it can be used to create complex chemical compounds that make up perfumes and solvents. 

Polyethylene Plastics

PVC and PVDF plastics are produced from ethylene or methane which in turn come from acetylene. These are sturdy plastics that are used in common household products and as durable and weather-resistant building materials. 

How to Safely Use Acetylene

Our acetylene is dissolved as a solvent which prevents decomposition and allows us to store greater quantities of it under lower pressure. Always use an acetylene canister in an unright position and in well-ventilated areas. Acetylene is lighter than air which means it can be trapped in roof spaces and empty areas that have inadequate ventilation or no extraction. 

The Right Product, Every Time

CK Supply provides acetylene cylinders in a variety of sizes or pressures, for any commercial or industrial purpose. Our aim is to make sure you have the correct materials and chemicals on hand to produce your products, fuel your processes, and get projects done the right way.
