Coagulation process for treatment of algal turbid water using Titanium-based coagulants

Project Member(s): Shon, H., Tijing, L., Phuntsho, S.

Funding or Partner Organisation: Korean Institute of Industrial Technology

Start year: 2015

Summary: In this project, Ti-based coagulants (i.e. TiCl4 and PTC) for water treatment through optimising a simple and effective protocol will be used to remove algae. Accordingly, the specific aims of this project are: (1) To identify the Ti-based flocculation properties and mechanisms for algal turbid water (2) To examine the formation, breakage and regrowth of algal flocs formed with Ti-based coagulants and compare the results with commonly used iron- and aluminium coagulants (3) To study and validate the complex soluble hydrolysed titanium species for water treatment (4) To design and standardise an effective post-treatment protocol to produce well-defined polytitanium coagulant
