Marine bacteria are key to novel wastewater treatment

27 February, 2023

The reuse of treated sewage effluent is a critical strategy to address water scarcity around the world.

Many industries produce highly saline wastewater that cannot be treated by conventional processes, while the use of seawater for toilet flushing could reduce the demand on valuable freshwater resources and energy required for desalination. However, current wastewater treatment technologies are sensitive to high salinity and have very low effectiveness in salt water.

Researchers in Pascal Saikaly’s group have addressed the problem with a novel energy-efficient wastewater treatment technology, known as anaerobic ammonium oxidation (annamox) for high-salinity wastewater treatment and nonpotable water reuse.
