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.

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.
