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 ...

Application of LEDs in Wastewater Treatment Plants
Wastewater treatment plants are prone to explosive risks due to the presence of volatile, flammable compounds inside the building. The Occupational Safety and Health Administration (OSHA) has highlighted the dangers of such hazardous environments through a federal safety investigation of a Canastota wastewater plant. In 2014, a worker died from third-degree burns after a devastating explosion ...

Survival of Helicobacter pylori in the wastewater treatment process and the receiving river in Michigan, USA
Contaminated water may play a key role in the transmission of Helicobacter pylori, resulting in gastrointestinal diseases in humans. The wastewater treatment process is an important barrier to control the transmission of H. pylori. However, the presence and viability of H. pylori in the treatment process is not well known. In this paper, the real colony morphology of H. pylori was confirmed ...

Evaluation of treatment schemes appropriate for wastewater reuse in Greece
The scope of this paper is to propose wastewater reuse quality criteria and treatment specifications for Greece, taking into consideration reuse priorities and secondary effluent characteristics. The proposed wastewater reclamation criteria and tertiary treatment schemes were evaluated in terms of feasibility and effectiveness through lab-scale experiments. The experimental data were processed by ...

An assessment of the checkpoint bioassay concept for full scale wastewater UV reactor validation
In an effort to help policy makers and manufacturers understand the impact of parameter uncertainties on UV reactor performance, a numerical bioassay model was developed by integrating a UV reactor model based on computational fluid dynamics with a Monte Carlo model developed to account for parameter uncertainty. For the model implemented, it was determined that reactor performance uncertainty ...

Response surface method for the optimisation of micropollutant removal in municipal wastewater treatment plant effluent with the UV/H2O2 advanced oxidation process
Experiments with the ultraviolet (UV)/H2O2 advanced oxidation process (AOP) were conducted to investigate the abatement of micropollutants in wastewater treatment plant effluent. The fluence and the starting concentration of H2O2 in a bench-scale batch reactor were varied according to response surface method (RSM) to examine their influence on the treatment efficiency. It was shown that the ...

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 ...
