Phenazone Wastewater Treatment

Phenazone, also known as antipyrine, is a synthetic compound classified as a pyrazole derivative.

It was first synthesized in the late 19th century and quickly gained popularity due to its analgesic and antipyretic properties. Over the years, phenazone found many applications in the medical field, making it an important pharmaceutical product.

However, its presence in water, particularly in wastewater, has raised concerns due to potential environmental and health risks.

This article looks at phenazone, its uses, impact on water, and ways to remove it. We will also introduce the Nyex Rosalox™ system by Arvia Technology as an efficient and eco-friendly water treatment solution.

Phenazone Removal From Water

Phenazone removal from water

Phenazone can be removed through conventional treatment method such GAC or reverse osmosis. However, a more efficient and eco-friendly solution would be our Nyex Rosalox technology. Our system is a combination of adsorption and oxidation and is really effective in Phenazone removal from water.

What we achieved

Our Nyex Rosalox system removed 88% down to 0.00041 µg/L from industrial wastewater.

How it works

What is Phenazone Used for?

Phenazone has been widely used in the medical field for its pain-relieving and fever-reducing properties. It’s used in medications for headaches, toothaches, period pain, and small injuries. Phenazone is also used in ear and eye drops to reduce pain and swelling.

In veterinary medicine, phenazone has been used for similar purposes in animals.

Its extensive applications in healthcare have contributed to a widespread presence in the environment.

However, despite its medical benefits, phenazone poses environmental challenges. Improper disposal and release can contaminate water, harming aquatic life and possibly entering the human food chain.

Phenazone in Water

The presence of phenazone in water can have both short and long-term consequences for the environment.

In the short term, it may lead to immediate toxicity to aquatic organisms, disrupting their natural ecosystems.

Long term continuous exposure to phenazone can result in bioaccumulation, where the compound accumulates in organisms over time. This leads to potential adverse effects on higher trophic levels, including humans.

Studies have shown that phenazone toxicity in water can persist for extended periods, depending on environmental conditions. This persistence can vary from days to months, making phenazone water treatment essential.

Phenazone removal methods

Several phenazone removal methods are currently employed; each has its advantages and disadvantages. Among these methods, oxidation, adsorption, and reverse osmosis stand out as some of the most commonly used phenazone removal options.

Phenazone removal by oxidation

Oxidation processes involve the use of chemical agents or advanced oxidation processes (AOPs) to break down phenazone molecules into non-hazardous byproducts. However, some oxidation methods may generate potentially harmful byproducts, making careful consideration necessary.

Phenazone removal by adsorption

Adsorption techniques, particularly using activated carbon (GAC), can effectively remove phenazone from water. Activated carbon for phenazone removal is effective as it is a highly porous material with a large surface area. This attracts and traps phenazone molecules. However, the spent carbon poses challenges for disposal or regeneration.

Phenazone removal by adsorption

Reverse Osmosis: Reverse osmosis (RO) has been used for removing various contaminants from water, including phenazone. RO employs a semi-permeable membrane to remove dissolved substances, ensuring cleaner water. But reverse osmosis for removing phenazone from water can be energy-intensive and may require careful monitoring to prevent fouling of the membrane.

Does Ozone Remove Phenazone from Water?

Ozone can be used in advanced oxidation processes for the removal of phenazone from water.

During the ozone treatment, the compound undergoes chemical breakdown, leading to the formation of more easily treatable byproducts.

Ozone treatment is effective in degrading phenazone and has been successfully applied in wastewater treatment.

Despite its efficacy, the use of ozone presents some concerns. Ozone itself is a toxic gas and requires careful handling to prevent harmful exposure. Additionally, ozone treatment can be energy-intensive, impacting the overall sustainability of the treatment process.

Does GAC Remove Phenazone from Water?

GAC adsorption techniques have proven to be effective in removing phenazone from wastewater. The highly porous nature of activated carbon allows it to adsorb phenazone molecules effectively. Additionally, GAC is known for its versatility and can be used in various treatment systems.

However, the use of GAC for phenazone removal also presents challenges. The spent carbon, laden with adsorbed contaminants, requires proper handling and disposal.

Furthermore, the adsorption capacity of GAC can diminish over time, necessitating regular replacement or regeneration of the carbon. For more information on GAC, see this article.

Among the various methods available, the Nyex Rosalox™ system by Arvia Technology emerges as a cutting-edge and eco-friendly solution for phenazone removal. This innovative system combines adsorption with an electrochemical oxidation process, providing an efficient and sustainable water treatment option.

The Nyex Rosalox™ system utilizes Arvia’s proprietary Nyex™ media, an advanced adsorbent material with a high affinity for pharmaceutical compounds like phenazone. The electrochemical oxidation process then regenerates the Nyex™, whilst at the same time oxidising the pollutants, ensuring long-lasting and cost-effective treatment.
