For many commercial and industrial operations, looking at ways to reduce water and wastewater monthly bill costs and ensure compliance with both current and future regulations, water reclaim is essential.

A major water treatment challenge encountered in the search for new water sources is the reduction of TOC and COD at one or more locations.

The purpose of this study is to show the importance of AOP process design and optimization and the significant implic

Introduction

An investigation into alternatives for refractory COD removal in industrial waste waters which is economically attractive and do not produce sludge lead to an evaluation of ozone based advanced oxidation processes.

The results of this ozone based AOP pilot study indicate that refractory COD from pre-treated refinery wastewater effluent can effectively be destroyed and is a viable alternative to traditional chemical

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 waste water (COD 1250 ppm) was circulated throughout the AOP reactor and ozone & H2O2 injected at various dose rates using Venturi-type injectors. Treated samples we

Both the public and local regulatory authorities are highly sensitive to odour nuisance.

Odour problems originate from the use of chemicals and solvents in industries such as foundries, electronics, chemicals, petrochemicals and pharmaceuticals but also from sewage treatment plants, food production, tanning, animal rendering. 

ESCO International, a company specialising in Ozone, UV and Advanced Oxidation Processes with the primary objective of resolving water issues on a global scale, has entered the final stages of a multi-million pound project with a large Oil & Gas company based in Russia. Following extensive site trials using a custom-designed industrial AOP pilot system, optimised results proved impressive for the company requirements.AOP pilot tests demonstrated significant drops in COD concentration, wit
