Wastewater treatment challenges faced by the petrochemical and refinery industry, and opportunities for water reuse

Refinery wastewater treatment and reuse

0 A tremendous amount of material has been written about wastewater treatment and reuse in recent years. This is partly due to the constantly changing technology in the field. Controversy surrounding the promulgation of regulations by the Environmental Protection Agency (EPA), and subsequent revisions, have added to the confusion. The purpose of this article is to attempt to tie this mass of in...

Integrated Membrane Processes (EDR-RO) for Water Reuse in the Petrochemical Industry

The objective of this work was to apply a hybrid process, including electrodialysis reversal (EDR) and reverse osmosis (RO) to the treatment of petrochemical wastewater in order to obtain process water for reuse. A water balance was carried out to defne the main water consumers and the process step that could receive the produced water. Additionally, toxicity assays wer...

Water reuse in Africa: challenges and opportunities

Population and urban growth is one of the major challenges facing Africa. Rapid urbanization poses major infrastructure, economic, environmental and social problems. Total water supply and sanitation coverage is extremely low particularly in sub-Saharan Africa (SSA) and cities are becoming to a large extent informal. Untreated urban wastewater is polluting water sources throughout SSA changing ...

Integrated Fixed-Film/ Activated Sludge (IFAS) for Refinery and Petrochemical Wastewater Treatment Plant Upgrades

Integrated Fixed-Film/Activated Sludge (IFAS) technologies have been gaining wide popularity as an innovative and efficient treatment process for achieving nitrification in refining and petro-chemical wastewater treatment plants. IFAS technologies are sometimes referred to as Hybrid systems as the process combines the benefits of fixed film systems into the suspended growth activated sludge pro...
