Small scale autonomous treatment • • • • • • • • • • • • •
Treatment for small communities (<1000 m3/day) No operator required 99.999 % reduction in microorganism and colloidals Low energy consumption ( use of solar energy) No logistics Steady ,autonomous treatment process Fast responding process Reliable and fail-safe Very low use of chemicals or no use of chemicals Minimum 2 mnth service (only change of consumables) Portable systems mounted in a container Remote control operation Competitive costs/m3 4

Application areas • • • • •
End of line use. Drinking water production Upgrading services Rain water harvesting Small communities – Villages, compounds, agglomorations, hotels, shopping malls, etc
• • • • • • •
Reuse of domestic water Effective use of water Exploring smaller sources ( networking) Modulair capacity building Reduced bureaucratic procedures Fast disaster response Re-use (grey-water) – Flushing, Washing, Irrigation, Infiltration, Awareness, Safe-Storage, Industrial use etc 7
