Abstract

Biological treatment of saline wastewater by standard activated-sludge cultures typically results in low chemical oxygen demand (COD) removal efficiencies as a result of plasmolysis of cells caused by high salt content (>1%). Removal of salt from wastewater before biological treatment by reverse osmosis or ion exchange would be quite costly. However, inclusion of salt-tolerant organisms in an activated-sludge culture to improve treatment efficiency is a practical approach developed and presented in this article.
