4 Misconceptions of AOP for Wastewater Treatment

Advanced Oxidation is a rather complex wastewater treatment process. The general concept of how the process works can be difficult to grasp at first, and the number of possible oxidation methods can seem daunting. Therefore, you turn to the internet for information, and try to analyze together all the information you find using various online resources. However, everything doesn’t always fit right, and you come up with ideas that may not be quite true.

If you happen to have any misconceptions, perhaps one of them will be discussed below. If it is not, check out the contact information at the end of this article to discuss this process with a well-informed expert.

Before we discuss the common misconceptions of the advanced oxidation process. We will discuss some of the basics of the advanced oxidation (AOP) process again for a quick reference.

AOP Solution Recap

Advanced oxidation is an oxidation process that centers around the creation of the very powerful hydroxyl radical (•OH). These highly reactive oxidization molecules are created from the degredation of certain compounds that also double as secondary oxidizers.

There are three oxidants in particular that are very effective: ozone, hydrogen peroxide, and ultraviolet light. They are used in various combinations with one another — ozone can also be used by itself — to produce the •OH molecule.

Ozone degrades in a complex process when exposed to high concentrations of hydroxide ions or hydrogen peroxide. A UV light can be used as a catalyst to break down ozone and hydrogen peroxide by using massless photons to break atomic bonds.

The light can also aid in adding an element of disinfection to the AOP system as well as oxidation.

Once the radicals are produced, they break the pollutant compounds into intermediates which are further broken down by the remaining radicals and original oxidants. In the end, the contaminants are mostly broken down into simple inorganic compounds like water, carbon dioxide, and salts.

AOP systems are mostly used in tertiary treatments, as they are sensitive to suspended solids and other compounds (known as hydroxyl scavengers). These scavengers reduce the oxidation efficiency by blocking UV radiation and reacting with the •OH radical over the target compounds.

Now that we’ve briefly reviewed the basics of AOP process, let’s move on to four misconceptions of this particular process....
