1. Ion Exchange Resins for Removal of Algal Toxins from Surface Water Fuhar Dixit MASc. Chemical And Biological Engineering University of British Columbia

2. Ion Exchange and Harmful Algal Blooms 2 Toxin Organics + Toxin NR 3 Cl Toxin NR 3 - - +- +- + - - - - - - + + - - - - + + - - - - Ion Exchange Process has never been investigated for the removal of algal toxins from surface water

3. Objectives and Methodologies  Examine the efficiency of ion exchange resins for the simultaneous removal of algal toxins and organic matter from natural water sources 3  Kinetic and Isotherm Studies  Resin Dosage Optimization  Contact Time  Kinetic Studies: 200mg/L Fig. Jar Tester and Ion Exchange Resins

4. 4 Results and Engineering Significance Ion Exchange is a potential process for the removal of algal toxins Charge Density and Molecular Weight of Organics influence the toxin uptake Results and Engineering Significance Efficiency and effectiveness of the ion exchange resins for different surface water matrices Efficient contact time Effective resin dose Comparison between surface and lab water studies 4
