 Output characterisation
OUTPUT SENTENCE

Biological oxidation unit of arsenite contaminated groundwater

 
OUTPUT TYPEidea/theory 
WATER TOPICQuality of natural systems 
KEYWORDSQuality of natural systems, Consumption, Industrial pollution 
KEYWORDS TYPEidea/theory, methodology, prototype, 
MARKET NEED TAILORED

Meeting drinking water limit

 
OUTPUT DESCRIPTION

Developed an experimental design of biological water treatment unit

 
STATE OF DEVELOPMENT

Transfer possible on other territories, other scale, (tested on industrial or mine waters)

 
INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS

Low acceptability by the end-users (policy maker, public authorities)

 
TRANSFERABILITY

Alternative to classical physico-chemical treatments : no need of nutrients, use of indigenous microflora potential to oxidize arsenic

 
POTENTIAL USERS/CLIENTS

SME, big industrial plants

 
 Estimation of risks
INNOVATIVE DISADVANTAGE

not yet published, Small scale Pilot, ?

ECONOMICAL RISKSNo great economical risks, robust and cheap process
TECHNICAL RISKSUse of endogenous biological microflora, possibility to reduce the risks by using material coated with an arsenic oxidizing bacteria
MARKET RISKSAvailability to find arsenic contaminated groundwater
SOCIAL RISKSRisk of user rejection. The team has conduced an Opinion survey on the bioprocess to better know its acceptability by the end-users; ?Acceptability criteria: ?low cost (not increase the water pricing) ?easy to use ?to better know the efficiency of the bio
 Steps ahead
NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE'

Implementation on rural water treatment station to improve its efficiency over time (> 6 months) Large scale demonstration; To prove that the bioprocess is innocuous for the health; Awareness and consultation of the stakeholders on the social acceptability

TYPE OF PARTNER FOR THE NEXT DEVELOPMENTSSME/Company
TASKS TO BE PERFORMED

Implementation of an industrialised pilot
