Why Is Scalable Advanced Oxidation Important To Industry?

Advanced oxidation has been around for quite some time and has proven its usefulness in water and wastewater treatment applications. Optimizing its use is continuously being studied, but there are already existing technologies that make it scalable for industrial and commercial use.

This article discusses the benefits of advanced oxidation in various applications and its advantages over other water and wastewater treatment processes. I will also talk about the importance of scalability of AOP treatment processes to industries and why advanced oxidation is the choice of many for treating tertiary water and wastewater. 

How Industries Benefit From Advanced Oxidation Technologies

Listed below are the advantages of the advanced oxidation process that can be highly beneficial for industrial and commercial use: 

Rapid reaction rates

The (hydroxyl) OH molecule has one of the fastest reaction rates among oxidants used in water and wastewater treatment processes. It has a high oxidation potential and has a non-selective nature, making it very versatile in a wide range of applications. Additionally, faster reaction rates translate to lower retention times, meaning water and wastewater can be treated quicker compared to conventional treatment processes such as chlorine or ozone.

Smaller land area requirement

Because of the fast reaction rate of advanced oxidation solutions, a smaller land area is needed to output the required flow rate of the system, including within tertiary industrial applications.

No new hazardous substances 

A big issue with chlorine disinfection is the production of toxic byproducts after treatment. To reduce but not eliminate these byproducts from affecting the water supply, filtration to remove any organic compounds is required. This results in additional costs that may not be economical in large-scale applications.

While advanced oxidation processes also have byproducts, they’re easier to deal with. Bromate and excess peroxide can be removed through a well-designed advanced oxidation system. Advanced oxidation can also convert through oxidation organic components in the water into stable inorganic compounds like salt and carbon dioxide.

Versatile application

The highly reactive hydroxyl (OH) radicals in AOP solutions can deal with most organic materials in the water. They can remove the most common contaminants in the reactor vessel, including a few of the trace heavy metals often found in water supplies.

Disinfects the water

Advanced oxidation can be combined with UV disinfection to kill any pathogens that survive in the water. This saves time and cost because the process eliminates the need to add another step in water and wastewater treatment.

Deals directly with contaminants

The advanced oxidation process doesn’t treat water and wastewater by separating pollutants to have them treated in another phase. Other treatment processes create byproducts like sludge that need to be dealt with separately, further increasing the cost of operations.

Treatment solutions using membranes only produce concentrated waste contaminants that have to be dealt with separately since they merely filter pollutants from the water supply. On the other hand, advanced oxidation technology reacts with the organic pollutants and inorganic contaminants to reduce them to harmless compounds that are easier to manage. Overall, AOP decreases the concentration of the contaminants in the effluent.

The hydroxyl radicals in AOP solutions are non-selective. After the contaminants are broken down, they form intermediates that also react with oxidants and mineralize into more manageable compounds. 

Other Industries That Can Benefit From Scaling Advanced Oxidation Systems

Several industries can benefit from advanced oxidation technology

The production of pharmaceutical drugs results in byproducts that can contaminate drinking water and aquatic environments. Pesticide runoffs from farms get mixed into the freshwater supply. Personal care products are washed down the drain and go to wastewater systems that they are linked to. Landfill leachate that contains a toxic cocktail of chemicals can leak into groundwater sources. 

Compounds of emerging concerns, specifically the byproducts from industries that deal with pesticides, pharmaceuticals, and personal care products, are recognized as potentially dangerous to natural water supplies. These contaminants have been detected in aquatic environments for years, but their numbers continue to rise at an alarming level as industries proliferate. 

These contaminants and micropollutants are difficult to remove using conventional water and wastewater treatment processes. A more efficient tertiary treatment method is necessary and this is where the advanced oxidation process (AOP) can help. 

The hydroxyl radical and reactive oxygen compounds in advanced oxidation technology are more powerful than almost all other oxidants found in other treatment processes. Its oxidation potential is twice that of chlorine as a disinfectant. It can reduce contaminant concentrations from hundreds of parts per million (ppm) to just a few parts per billion (ppb). Ozone, ultraviolet light, and hydrogen peroxide are the components often combined to create sufficient quantities of hydroxyl radicals for managing organic contaminants and inorganic pollutants in water supplies. 

Why Advanced Oxidation Is The Best Solution

Numerous pollutants are tough to get rid of by biological, chemical, or physical means alone. Unfortunately, traditional treatment systems cannot completely remove these contaminants. The byproducts can have a long-term impact on the environment and the ecosystem in the affected areas. 

A study shows that advanced oxidation offers a high removal percentage of these contaminants. Advanced oxidation solutions are effective in decontaminating water and wastewater sources of compounds that aren’t eliminated with conventional treatment & purification processes. AOPs are often added as a tertiary step to further treatment processes and reinforce existing filtration systems. This ultimately prevents the integration of emerging contaminants into the environment. 

Augmenting existing treatment processes can be costly, regardless of the industry. The main problems with existing water and wastewater treatment systems are related to energy consumption, the complexity of chemical processes, and environmental footprint. All these are related to the cost of operations, which is the biggest factor in determining the scalability and efficiency of chemical treatment procedures.

Additionally, changing quality requirements can make it challenging to keep the cost of operations constant. The technologies, processes, and regulations will change over time, and these will impact the water quality needed by your facility. Oftentimes, the solution is to install additional equipment or augment facilities and processes to meet discharge regulations. 

Advanced oxidation technologies are already being used at full scale for drinking water treatment and tertiary wastewater processing. Genclean Treatment Solutions, a division of Genesis Water Technologies is a trusted company offering scalable liquid AOP technology that can be applied to industrial, commercial, and municipal treatment applications. 

How Can Advanced Oxidation Deal WIth Scalability Challenges

The main problem with the AOP process is the operating cost, but it can be resolved using several means

Firstly, the integration of renewable energy is recommended. AOPs activated by UV not only can benefit from sun irradiation but also from the production of energy through solar power. 

A study shows that adding a co-catalyst to AOP systems can reduce the amount of hydrogen peroxide and ferrous catalyst needed while preventing the formation of sludge. It’s an inexpensive way to catalyze reactions and reduce the development of byproducts that can be hard to deal with. Since there’s an increasing global need for clean water supplies, it’s critical to have a cost-effective solution like this to decontaminate polluted water sources. 

While AOPs have a wide range of applicability, the treatment target should be specific and selective to reduce cost and optimize disinfection capacity. With this understanding, valuable elements like oxidants and catalysts will not be wasted without purpose.

Lastly, AOPs are best used in combination with traditional treatment technologies. AOPs alone cannot replace existing water and wastewater treatments from an economic standpoint. It is more cost-effective and feasible to integrate it into existing disinfection processes.
