1. What treatment? Neutralization and partial desalination - essential for protection of the environment and human health and, Complete desalination - drinking water needed during the next four years

2. Limestone handling and dosing system

3. Full-scale neutralization plants Iluka Resources, Hamilton Namakwa Sands, Lutzville

4. Fe(II)-removal with sequence batch operation

5. Treatment at Grootvlei water (108 Ml/d) Grootvlei Mine where contains 100 mg/l iron(II) and 350 mg/l alkalinity. Currently this water is treated at a cost of R3.7 million/month, using lime and oxygen. 100mg/l need to be oxidised in a more cost-effective way.

6. Desalination Need 400 Ml/d by 2014 in Gauteng Coal mining sector already produce 35 Ml/d drinking water from mine water in Mpumalanga

7. CSIR ABC Desalination process (Alkali-Barium-Calcium) Lime and/or CaS pre-treatment Barium treatment for SO4 removal Sludge processing

8. Western Utilities Corporation pilot plant to evaluate ABC process

9. TUT MBO process (magnesium-barium-oxide) Metal removal with Mg(OH) 2 SO 4 and Mg removal with Ba(OH) 2 Sludge processing

10. Soshanguve pilot plant for freeze desalination Refrigeration unit Heat exchangers Ice filter

11. Ice production Official launch – 25 October 2011 at 13:00 as Soshanguve Campus of TUT
