Preparation and characterization of titanium dioxide produced from Ti-salt flocculated sludge in wastewater treatment.

초록

Titanium tetrachloride and titanium sulfate have recently been investigated as alternative coagulants for the removal of different pollutants from contaminated water or wastewater. The removal ratio of oranic compounds in wastewater was comparable to the commonly used Al- and Fe-salt coagulants while the settling of sludge was faster, which made the subsequent separation process easier.
