 Output characterisation
OUTPUT SENTENCE

Reactive layer: a reactive organic bed that, once installed in the surface of infiltration ponds, enhance the biodegradation and sorption of recalcitrant compounds during aquifer recharge
- hydROL: a numerical code to simulate the reactive layers reactions and groundwater flow during aquifer recharge 

 
OUTPUT TYPEconceptual model 
WATER TOPICScarcity and Droughts 
MARKET NEED TAILORED

What policy objectives or what technological solution does the output solve or fulfil?
- Groundwater quality
- The available of groundwater during scarcity periods
- The improvement of recharge water quality

 
OUTPUT DESCRIPTION

An organic reactive layer to be placed in recharge ponds to improve water quality

 
STATE OF DEVELOPMENT

full-scale implementation As it is a demonstrative project, Sant Vicenç dels Horts (Barcelona) was selected as the test site. It is a real recharge system

 
INNOVATIVE ASPECTS AND ADVANTAGES

This technology has been developed in the context of permeable reactive layers to remediate groundwater contamination. This project applies this technology to a managed Aquifer Recharge project where recharge is facilitated through infiltration ponds. The main advantage is that the technology has been widely developed for other purposes. Has low cost of implementation and its performance can be easily detected.

 
INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS

To CETAQUA. Each partner owns the results obtained in their tasks.
Patente pending for the methodology

 
TRANSFERABILITY

Yes, after the a previous site study to analyse the site conditions

 
POTENTIAL USERS/CLIENTS

Operators of managed aquifer recharge facilities (e.g. Water Agencies, water utilities).

 
BUSINNESS CASENo 
 Estimation of risks
INNOVATIVE DISADVANTAGE

The reactive layer has a limited life. The duration of the reactive layer is not yet well understood. The system interpretation requires a good hydrogeology knowledge.

EVALUATION OF RISKS FOR OUTPUT USERS

Low risk on legal aspects but it is related to a technology (MAR) that has legal barriers at least in Spain since it has not been commonly used..
Related to market aspects, it is not complicated to implement as it has low costs and there are similar products.
There are social barriers related to social perception, more exchange of information with local population is here needed.
There are also administrative permissions regarding soil use which might hinder the uptake of this output

ECONOMICAL RISKSNo high economical risks regarding economical aspects
TECHNICAL RISKSLow technical risks
MARKET RISKSThis is a very innovative output, which however has a lack of demand
SOCIAL RISKSNo social acceptance of the technology due to lack of awareness and information on it.
 Steps ahead
NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE'

- To be implemented in more places
- To asses about its effectiveness with more contaminants
- To demonstrate the duration of the technology in different contexts

INVOLVEMENT OF THE OWNER FOR THE NEXT STEPSThere is no other research project on-going with the topic of reactive organic layer, despite more experiences and laboratory work is needed DEMEAU project (FP7) will study the removal of micropollutants through MAR systems, but under natural conditions. At the moment, transfer of results and dissemination will continue.
TYPE OF PARTNER FOR THE NEXT DEVELOPMENTSTo have a successful implementation, the involvement of the following organisations will be needed: - Public administrations (Water Agencies) - Water utilities As they are the end-users of reactive layer technology.
TASKS TO BE PERFORMED

Transfer sessions (specially focussed in the AGBAR group).

COLLABORATION DETAILS

It will be useful to have transfer sessions with other potential clients (water utilities, water agencies), but due to the lack of budget it is not expected.

 Background
PROJECT NAMEEnhancement of Soil Aquifer Treatment to Improve the Quality of Recharge Water in the Llobregat River Delta Aquifer 
PROJECT ACRONYMENSAT 
PROJECT DESCRIPTIONThis project aims at improving the quality of the recharge water at Sant Vicenç dels Horts Managed Aquifer Recharge site by means of the implementation of an organic substrate layer for enhancing Soil Aquifer Treatment (SAT). The project will: • Demonstrate the application of Soil Aquifer Treatment (SAT) during aquifer recharge episodes with reclaimed water or low quality river water. • Develop a modelling tool (a software) for the prediction at the field scale of the impact of an organic substrate in terms of hydraulics and geochemistry during infiltration practices. • Adapt and transfer results obtained (hydrogeochemical model and methodology for the selection, implementation and validation of the tested technology) to aquifer recharge sites in Europe.
