Background

• Watershortage –watercrisis

• Environmental issues

• Energy consumption

• Transmissionlines/distribution networks

• World population 50 % Urban- 50 % Rural

• Wateracces 64 % Urban- 30 % Rural

• High volume centralized treatment-plants

• Leakages

• Growing population increasing waterconsumption

• 80-20 rule watersources vs exploration.

• Effective water usage

• Awareness

• Rainwater harvesting

• Reuse/ Cascading Grey-water treatment

• Terror

• Nature

• Millenium goals

• Health

• Culture

4

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

5

• WHO guidelines for drinkingwater quality

• TS-266

• EU • Waste-water treatment directive

• Drinking water directive

• Dutch water standards ( water law)

6

EUF removal

EUF removal with Nano filtration extended

7

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

History of development

• Dutch watertechnology

• Dutch trade mission september 2006

• Interest ISKI , DSI

• License agreements

Local small scale water-treatment

• Finance by Dutch government (PvW)

– Prove economical feasability

– No technological feasability

– Known technology in unique configuration

– Benefits for both countries

• Start august 2008- may 2009

• Pilot-process test-equipment at ISKI for demo.
