1. WORKSHOP Steyr, 2005 Potential New Technologies And Testing Of Mobile Water Treatment Units

2. WORKSHOP Steyr, 2005 Scope of the workshop achieve an overview on suppliers and technologies potential to be used by RC / RC correspond to our standardized Specialized WatSan ERU

3. WORKSHOP Steyr, 2005 Specialized WatSan ERU Water production 120.000 l/day Minimum quality: WHO standards Capability to treat high turbidity Capability to treat high microbiological contamination Simple to operate, easy to maintain

4. WORKSHOP Steyr, 2005 Participating companies SETA www.gruposeta.com Berkefeld www.berkefeld.de Scan-Water www.scan-water.com Josab www.josab.com Kaercher www.kaercher-futuretech.com

5. WORKSHOP Steyr, 2005 Preparation of raw water First day: turbidity Second day: microbiology

6. WORKSHOP Steyr, 2005 SETA 3000 Pretreatment Sand filter Active carbon filter Chlorination

7. WORKSHOP Steyr, 2005 SETA 3000 Compact on a trailer Pretreatment able to handle high turbidity Safe drinking water Consumables: Alum, HTH

8. WORKSHOP Steyr, 2005 Scan-Water Purification unit 4 m3/hr Flocculation / Coagulation unit Sand filter Active carbon filter Chlorination

9. WORKSHOP Steyr, 2005 Scan-Water Purification unit 4 m3/hr Very easy to operate Simple unit With additional pretreatment able to handle turbidity Good price – performance ratio

10. WORKSHOP Steyr, 2005 Josab Aqualite Portable Pro (500 l/hr) No pretreatment Aqualite (zeolite structure) filter UV radiation Post-Chlorination

11. WORKSHOP Steyr, 2005 Josab Aqualite Portable Pro (500 l/hr) Best results for microbiological tests Quick to install Struggles with high turbidity Chlorination possible

12. WORKSHOP Steyr, 2005 Kaercher RO WTC 500 + Filatwist Prefiltration with filter-bag Prefilter Filatwist (up to 4 m3/hr) in development Reverse Osmosis UV radiation Post-Chlorination

13. WORKSHOP Steyr, 2005 Kaercher RO WTC 500 + Filatwist Prefilter Filatwist demonstration unit / in development Prefiltration Filter-bag clogs immediately Reverse Osmosis needs clear water High-tech machinery High costs – Low output

14. WORKSHOP Steyr, 2005 Berkefeld BERU 2000/700 Pretreatment with disc-filter Ultrafiltration Reverse Osmosis (optional) Fully automatic Trailer mounted (optional)

15. WORKSHOP Steyr, 2005 Berkefeld BERU 2000/700 Long time for start up Broke when becoming operational Material defect, no repair possible Risk of control system failure? Trailer not practical option

16. WORKSHOP Steyr, 2005 Overall comments Simple technology suits best High turbidity requires pretreatment Microbiological tests ok for all units Post-chlorination necessary in emergencies Different solutions regarding comfort and material SETA and Scan-Water with best results
