Ukaigwe, Sandra A

The current drive for energy neutrality, drastic reduction in energy costs and increasingly stringent wastewater discharge rules has led to the quest for the development of more energy efficient and effective wastewater treatment technologies. MABR is one of these developing technologies. MABR is...

Brace, Noah

The true value of water has not yet been captured in municipal water planning and management, despite the increasing availability of technologies designed to create value from wastewater. Adapting system processes for water reclamation, energy generation, and production of other outputs (such as...

Cellulose nanocrystals (CNCs) are nanoparticles with high aspect ratios and excellent surface tunability and are processed from renewable bioresource. CNCs possess unique surface and colloidal properties which makes it an efficient depletion inducer for flocculating colloidal sized bacteria from...

Ammonium-N and phosphate-P-rich anaerobic digester sludge liquor recovered during sewage sludge dewatering contributes more than 30% of the total nitrogen loading when returned to the municipal wastewater plant. Hence, side stream treatment could offer an economic alternative given its relatively...

The demand for fresh water is steadily increasing as a result of the increasing human populations and activities. On the other hand, water sources are limited, especially as the global warming continues to change the quantities and distribution of water all over the world. Therefore, focusing the...
