Work Packages

In order to achieve the project objectives the following work packages have been established:

WP1: Pilot tests (CDI, UO) at laboratory-scale using model water

At the University of Karlsruhe tests with CDI and RO-modules will be carried out to determine the optimal process conditions and relevant parameters. Results will provide the basis for the design of the plant and trial test on-site.

WP2: Computer-based system analysis

A computer-based modeling of the CDI process based on theoretical models will be created to simulate the physical processes within the CDI and RO modules to study the influence of all relevant parameters on the total energy consumption and resulting water quality for the piloting in Vietnam.  A comparison of the results of WP1 and the simulation will support evaluation of the model.

WP3: Concept for the autonomous supply with renewable energy

An energy concept is carried out to evaluate the autonomous supply of the system using renewable energy (conventional photovoltaic (PV) + thermoelectric generator (TEG) + wind turbine). The objective of the concept is the identification and evaluation of the feasibility and viability of the modular system and the identification of suitable concepts for providing energy to small and medium scale water purification plants in Vietnam.

WP4: Pilot tests in Vietnam

This work package comprises the implementation of experiments with the pilot plants in Vietnam for the systematic investigation of the energy yield of the combined processes and will be carried out in two different locations:

The in-situ treatment plant will be piloted in the An Giang district for Fe/As containing groundwater as a pretreatment process and in combination with CDI. Furthermore, the CDI/RO combination process will be tested at the seashore on the desalination of seawater.

WP5: Develop of a customized methodology for a multidimensional sustainability evaluation

The sustainability assessment comprises the development of a customized methodology for the individual processes and the overall system, taking into account relevant criteria on ecologic, economic and social aspects.

WP6: Implementation of a comprehensive multi-dimensional sustainability assessment

WP6 is used finally to the holistic sustainability evaluation of methods processing the relevant results from all other work packages. The assessment is made based on the compiled information regarding system-specific parameters and external framework conditions. In this work package, the evaluation methodology of WP5 will be applied and corrected. Finally, the transferability in other fields of application will be applied and documented.
