Pilot for remineralization of water
Remineralization/neutralisation of drinking water through injection of lime milk suspension.
|KEYWORDS||lime milk suspension, water treatment, drinking water|
|MARKET NEED TAILORED|
End of neutralite exploitation in Britanny, implying extra costs in neutralization/remineralization, new solutions were needed in order to contain upkeep costs.
This output is a prototype on a small scale drinking water plant (for 170 people), dedicated to remineralization and neutralisation of waters, for small local authorities not having a big budget.
|STATE OF DEVELOPMENT|
A 1 m3/h prototype has been successfully tested as a pilot, using recycled parts. A mobile unit is currently in development and construction with new parts, in order to test in real life conditions up to 10 m3/h.
|INNOVATIVE ASPECTS AND ADVANTAGES|
No extra costs linked to neutralite usage
Investment in the beginning is twice cheaper, compared to a classical neutralization/remineralization.
Micronized lime milk suspension wasn't tested before on small plants, and was usually injected at the beginning of the process, not at the end.
|INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS|
Office International de l'eau at the moment. Information should be made public at the end of 2014.
Any small/medium drinking water plant with acidic or soft properties for the treated water, up to 10 m3/h at most for financial reasons.
Any water utilities or local authorities managing their own plants
|Estimation of risks|
Upkeep costs are rather high. The installation is twice cheaper considering investment costs, compared to classical remineralization units, but this advantage gets weared thin after 10-12 years of intensive use.
|EVALUATION OF RISKS FOR OUTPUT USERS|
Investment is low, upkeep costs can get out of hand if not watched carefully.
Filters for the particles of lime milk can be clogged occasionnally.
There are a few neutralisation processes already existing, but remineralization wasn't existing on small/medium drinking water plants.
|ECONOMICAL RISKS||No risk on investment, low risk on running operations|
|TECHNICAL RISKS||Low risk|
|MARKET RISKS||Low risk|
|SOCIAL RISKS||No risk|
|NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE'|
Pilot tests on real life conditions
|INVOLVEMENT OF THE OWNER FOR THE NEXT STEPS||Research for potential users in order to run tests|
|TYPE OF PARTNER FOR THE NEXT DEVELOPMENTS||SME for CO2 injection|
|TASKS TO BE PERFORMED|
Completion of pilot unit
Tests of pilot unit in real life conditions
|Estimation of ressources|
|RESOURCES FOR NEXT STEPS|
Financial support for tests on hands.
|FORESEEN COSTS FOR NEXT STEPS|
Up to 20 000 € for real life conditions tests on a small drinking water plant.
