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

WORKSHOP Steyr, 2005Kaercher 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

WORKSHOP Steyr, 2005

Berkefeld BERU 2000/700

• Pretreatment with disc-filter• Ultrafiltration• Reverse Osmosis (optional)• Fully automatic• Trailer mounted (optional)

WORKSHOP Steyr, 2005Berkefeld 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

WORKSHOP Steyr, 2005Overall 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
