advanced oxidation process advantages and disadvantages, types of advanced oxidation process, advantages and disadvantages of oxidation

Introduction

Many pollutants are difficult to reduce by physical, chemical, or biological means alone, in many water and wastewater treatment applications. Pharmaceutical drug contamination, in drinking water and aquatic environments, has become a growing concern in recent years. Pesticides are carried into freshwater supplies by farm runoff. Personal care products are typically washed down the drain, into the system to which they are connected.

Some pollutants are large, while some are so small. Such contaminants are classified as micropollutants. Because of their size, they are difficult to remove from water and wastewater using certain methods. A powerful oxidation process is required for more efficient removal, and this process is known as the advanced oxidation process(AOP).

What are the Benefits of Advanced Oxidation Process?

The AOP generates potent oxidizing agents in the form of hydroxide (OH-), but more specifically, its neutral variant, the hydroxyl radical (OH). Ozone (O3), hydrogen peroxide (H2O2), and ultraviolet light (UV) are frequently used in various combinations, to produce enough OH to degrade organic, and some inorganic pollutants.

Because these radicals are non-selective, they attack almost all organic materials. These contaminants form intermediates, after being broken down by the OH radical. These intermediates react with oxidants, and mineralize to form stable compounds.

Benefits of advanced oxidation process

Following are some of the perks of using this process:

·         Rapid response times

The OH molecule has some of the fastest reaction rates of all oxidants used to treat water and wastewater, due to its high oxidation potentials and non-selective nature. Retention times are much shorter than in other conventional treatment processes, due to the rapid reactions.

·         The smallest possible footprint

Advanced oxidation process units require little land area, to process the system's required flow rate due to the OH radical's oxidation power.

·         New hazardous substances not initiated into water

One issue with chlorine disinfection is the formation of highly toxic by-products (DPBs) following treatment. To avoid these by-products, an additional de-chlorination step is frequently required, before the treated water can be used. Combining OH molecules can result in the formation of water.

The main issues would be bromate formation and excess peroxide, which can both be addressed in a well-designed advanced oxidation process system.

·         Organic mineralization

AOP has the ability to convert organic materials in water into stable inorganic compounds, such as water, carbon dioxide, and salts.

·         Treatment of nearly all organic materials and removal of some heavy metals

Because of OH's highly reactive nature, these molecules will attack almost any organic material without discrimination, allowing them to remove a diverse range of contaminants, including a few heavy metals, in a single reactor vessel.

·         Can be used for disinfection

The oxidation power of AOP systems, especially when combined with UV disinfection, allows them to act as a disinfection step for pathogens, which may be present in the water.

·         As opposed to chemical or biological processes, there is no sludge production

Water and wastewater are not treated by transferring pollutants to a different phase, inan oxidation process. Other treatment processes produce solids like sludge, which must be filtered and handled separately.

·         It does not separate waste for subsequent processing

Because membranes only separate clean water from pollutant compounds, they result in higher concentrations of waste contaminants. Meanwhile, AOP reacts directly with pollutants, converting them to innocuous compounds. As a result of this process, their concentrations in the effluent are reduced.

Conclusion

Advanced oxidation has been around for a while. As a result, while this process has more than proven its worth, it is still being optimized. It is a powerful treatment process with numerous advantages.
