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...

Cryptosporidium, a waterborne protozoan pathogen that can cause gastrointestinal illness, is often found in surface waters that are used to supply drinking water. Filtration is a major barrier against Cryptosporidium in drinking water treatment processes. However, interactions between oocysts and...
