The Combined Effect of Bubble and Photo Catalysis Technology in BTEX Removal from Produced Water

Among the several ways used in wastewater treatment, photocatalysis process is a more novel and alternative that increasingly employed recent years. This work aims to improve performance of photocatalyst by using air bubbles removing BTEX from produced water as an indicator efficiency. The study also shows effect influencing factors (pH residence time) on process. was done rectangular column with dimensions 200 mm width, 30 depth, 1500 height. Commercial titanium oxide (TiO2) coated plate varnish source photocatalyst. experiment carried out under different values gas flow rate (0-3 L/min) evaluate its process, other variables pH (3-11), irradiation time (30-120) min studied. A new method coating adopted alumina adhesive. characteristics results show has hydrophilic properties there no significant change crystal structure TiO2 nanoparticles before after 60 h photocatalytic indicating still effective usage conditions. introduction enhances removal efficiency significantly best effectiveness 93% when = 5 90 90% 3 120 min. reached 86% 7 all at L/min. percentage decreased 9 11, reaching 64% 50%, respectively Copyright © 2022 Authors, Published BCREC Group. open access article CC BY-SA License (https://creativecommons.org/licenses/by-sa/4.0).
