A tool for the on-site and on-line measurement of macro parameters and trace metals in all water types

Will bring to the prototype a tool for monitoring water quality based on voltammetric analysis by boron doped diamond electrodes (fe, cu, zn, as, ag, pb, ni) and ion selective electrodes (nh4, no3, cl, k, ca, na) for all water types.

The AQUASENSE project develops an on-site tool which can analyse up to 15 macro parameters (order of magnitude mg/l) and trace metals based on ion selective electrodes and boron-doped diamond electrodes. These combined electrode techniques will be optimised to suit analyses for all types of water with a wide range in chemical composition (from drinking water to wastewater) and temperature (4 - 40 degrees Celsius). The tool can be used as a field device, or for remote stand-alone monitoring. Use of this tool will lead to better implementation and policing of water related legislation, and therefore to a better quality of life. The AQUASENSE project aims to develop a new tool for the simultaneous analysis of macro parameters (water level, electrical conductivity, temperature, depth, dissolved oxygen, pH, Eh, NH4+, NO3-, Na+, Ca2+, K+, Cl, F- and H2S) and trace metals (Fe, Mn, Cu, Pb, Zn, Cr, Ni, As, Ag, and Cd). This will enable the AQUASENSE partners to gain a market advantage in monitoring, compliance, and rapid response. The project has the following verifiable deliverable: - To develop and test boron doped diamond electrodes (BDDEs) for the analysis and monitoring of trace metals (Fe, Mn, Cu, Pb, Zn, Cr, Ni, As, Ag, and Cd) in all types of water. - To customise and test new ion selective electrodes (ISEs) for the analysis and monitoring of macro parameters (pH, Eh, Nh4+, NO3-, Na+, Ca2+, K+, Cl-, F- and H2S) in all water types. - The BDDEs and ISEs must generate precise and accurate results at depths down to 100 metres and over a large temperature range (1-40 degrees Celsius). - To develop and build a monitoring tool that contains both the ISEs and BDDEs with a diameter smaller than 64 mm so that it fits in most European water wells. - To incorporate a gamma detector for independent K determination in one prototype. - To create data archives for the measured sites over the project duration for an optimised application of multi-parameter devices for practical situations. - To develop a fast and robust calibration procedure. - An artificial neural network correcting for interferences, T dependence, ionic strength. - To develop and test integrated software for processing, modelling and quantifying the analytical data, with automated calibration and data transmission when needed. - To run extensive field trials on test sites of the AQUASENSE partners. Each site will be chosen to reflect the various water types. This innovative EUREKA project is divided into two research (definition) phases and one development (implementation) phase. The first inception phase is needed to collect all relevant data from literature sources, and to establish the technical specifications needed in the tool. This will open an exchange of information and provide a kick-start to the next and main research phase where all the hardware and software components needed to make the prototypes will be designed and tested. The main focus is on the research into development, testing and construction of the AQUASENSE tool consisting of sensors for determination of physical and macro parameters and trace metals. This will include new hardware such as BDDEs and ISEs. Dedicated software will provide the data acquisition, transformation and interpretation. The second phase of research has been divided into five tasks, and has the important go/no go point of whether to construct the prototypes at month 24. Discussions with end-users will also shape the technical specifications of the tools to be built. The implementation phase will focus on validating the prototype through complete surveys at a number of sites provided by the AQUASENSE partners, who will also perform the surveys. There will be a number of long term monitoring studies (6 months) to test the stability of the device. There must be a full interpretation of data, and verification by other methods on-site, so that a proper evaluation of the technologies can be made. During the final task of the project, the technical requirements of potential users will have been assessed, and this will form the basis of market introduction. The important point is to advertise the technologies to potential users through direct marketing: A business plan will guide the development and exploitation of the technologies, looking for capital investment to allow production of the tools to proceed unhindered. The port project market introduction includes: - Market survey in Europe and Asia. - Dissemination of results from case history studies in this project. - Search for investment capital for production of units, Sales of licenses for hardware. Keywords: ISE (Ion-Selective Electrode) sensor tool, water analyses, voltammetric methods.
