Advanced oxidation technologies for Produced Water Treatment

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, with an initial level of up to 300ppm to less than 50 ppm (limit required by the refinery). More interestingly the oil concentrations were also noted and showed very promising results, dropping from a maximum of 20 ppm down to less than 0.1ppm. Finally in terms of turbidity, tests demonstrated a drop from a maximum value of 4.50 FTU down to a minimum value of 0.20 FTU. 

After several successful re-runs the company decided to seek ESCO International’s expertise to design a full scale advanced oxidation system required to treat a flow rate of  up to 900 m3/h. 

The water treatment facility will treat up to 22,000.00 m3 of water daily, which will be used primarily for recycle and re-use or environmentally safe discharge taking the company a big step in the direction of an environmentally friendly, economical and more sustainable future.

This project demonstrates ESCO’s main focus of providing companies with state-of-the-art water treatment methods suited to their specific needs.
