Titanium compounds are very perspective reagents for water treatment because of their many outbreaking benefits compared to traditional coagulants – smaller dosage, lesser pH-dependency, they are biologically inert, work at low water temperature. But they have some technological issues, preventing them from wide use. One of the ways to overcome this issues shown in this article. Results of use of nanoencapsulation of Ti(IV) salts into solvable cells shown. This way allows to overcome problem with too quick hydrolysis and evenly distribution of coagulant in treated water. Also titanium coagulant was practically compared to traditional coagulant to show benefits of titanium-based coagulants
