Oxidative degradation of COD in Petrochemical facility using Ozone-based advanced oxidation
The aim of this study was to investigate the use of ozone-based advanced oxidation processes for the oxidative destruction of COD in a petrochemical facility. Several AOP experiments were carried out in order to select and optimise the successful treatment option. A LABO3-AOP pilot unit was used where filtered wastewater (COD 1250 ppm) was circulated throughout the AOP reactor and ozone & ...

Chemical and toxicological evaluation of transformation products during advanced oxidation processes
The entry of pharmaceuticals into the water cycle from sewage treatment plants is of growing concern because environmental effects are evident at trace levels. Ozonation, UV- and UV/H2O2-treatment were tested as an additional step in waste water treatment because they have been proven to be effective in eliminating aqueous organic contaminants. The pharmaceuticals carbamazepine, ciprofloxacin, ...

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 ...

Oxidative destruction of foaming agent, COD and TOC in wastewater using advanced oxidation technologies
In recent years, improvement in ozone based advanced oxidation process design and efficiency resulted in lower capital and operating costs. An investigation into alternatives for hard COD, TOC and foaming agent oxidative destruction which is economically attractive and do not generate sludge, lead to the evaluation of our ozone based advanced oxidation processes (AOP). The results of this pilot ...

Full Scale advanced oxidation process for TOC removal and cost reduction by reclaiming water
For many commercial and industrial operations, looking at ways to reduce water and wastewater monthly bill costs, water reclaim is essential. A major water treatment challenge encountered in the search for new water sources is the reduction of total organic carbon (TOC) and Chemical Oxygen Demand (COD) at one or more locations. Properly designed advanced oxidation processes have demonstrated ...

An advanced oxidation process using ionized gas for wastewater treatment
This study on removing non-degradable materials in wastewater focused primarily on advanced oxidation methods such as ozone, ozone/UV and ozone/H2O2. Wastewater treatment using an ionized gas from plasma has been actively progressing. The ionized gas involves reactive species such as O2+, O2− cluster, O radical and OH radical. Since the ionized gas method has such outstanding characteristics as ...

Degradation and changes in toxicity and biodegradability of tetracycline during ozone/ultraviolet-based advanced oxidation
Advanced oxidation processes (AOPs) composed of O3, H2O2 and ultraviolet (UV) were applied to degrade tetracycline (TC). Degradation efficiency was evaluated in terms of changes in absorbance (ABS) and total organic carbon (TOC). The change in biotoxicity was monitored with Escherichia coli and Vibrio fischeri. The improvement in biodegradability during oxidation was demonstrated through 5-day ...

Biological wastewater treatment followed by physicochemical treatment for the removal of fluorinated surfactants
Perfluorinated surfactants (PFS) have become compounds of high concern during the last decade. While “conventional surfactants” are degraded to a great extent in the biological wastewater treatment process, partly or perfluorinated surfactants are not only stable against biodegradation but also against oxidizing agents, they even resist OH-radical attacks. Our objectives were to eliminate the ...

HF Pure Water VS. The Coffee Borer Beetle
Recently, HF Pure Water successfully installed a Chlorine Removal System at a small coffee farm on the big island of Hawaii. Like many coffee farms in the area and around the world, the coffee bean crop had been devastated by the Coffee Borer Beetle. An all-out effort was needed to rid the farm’s crops of this beetle as many small farms has had their entire crop destroyed, resulting in ...
