Project Description

INNOVEOX – Training of a new generation of researchers in Innovative Electrochemical Oxidation processes for the removal and analysis of micro-pollutants in water streams

It has been demonstrated that organic chemical pollutants are still putting half of the European freshwater system at risk. The INNOVEOX R&D training network was built to address and provide a solution for this considerable challenge: to boost innovative electrochemical wastewater treatment techniques to effectively degrade highly hazardous organic micro-pollutants, reducing environmental pollution and improving the European quality of life and health. By setting up a training frame to educate the next generation of highly-qualified ESRs in one of the most promising fields in micro-pollutant degradation, this will enable to generate important innovations, necessary to create a new level of EU excellence and reinforce EU R&D capacity in the field.

Research project: In a typical plasma based Advanced Oxidation Process (AOP) the degradation efficiency of the process is often limited by the mass transport of highly reactive chemical species from the plasma to the liquid phase. Recently, a large number of plasma reactor configurations have been reported and show an enormous variation in the efficiency of micro-pollutant degradation. Typically, one of the most efficient group of reactors involve spraying the contaminated liquid directly through the plasma region; this is attributed to the direct-contact and large-surface area between the aerosolised liquid and plasma. In this project, the ESR will explore the liquid spray reactor configuration and aim to maximise the degradation efficiency by enhancing the plasma stability and fluid-dynamics properties of the design. Spraying liquid through a plasma has the potential to disrupt the discharge and reduce the efficiency. To overcome this, the ESR will construct a spray-type reactor and investigate its key parameters, such as flow rate, aerosol size and plasma volume to establish the most stable operating conditions. Using a Particle Imaging Velocimetry (PIV) system, the ESR will quantify the velocity profiles of aerosols passing through the reactor, measurements that will be supported by computational fluid dynamics modelling. The characterisation activity will be used to iteratively enhance of the reactor design in terms of mass transport. Ultimately, the optimised reactor configuration will be compared against alternative reactor configurations already available in Liverpool.

In addition to their individual scientific projects, all fellows will benefit from further continuing education, which includes internships and secondments, a variety of training modules as well as transferable skills courses and active participation in workshops and conferences.

Conditions of international mobility of researchers: Researchers are required to undertake trans-national mobility (i.e. move from one country to another) when taking up the appointment. At the time of selection by the host organisation, researchers must not have resided or carried out their main activity (work, studies, etc.) in the country of their host organisation for more than 12 months in the 3 years immediately prior to their recruitment. Short stays, such as holidays, are not taken into account.

On-line Recruitment Procedure: All applications proceed through the on-line recruitment portal on the innoveox.eu website. Candidates provide all requested information including a detailed CV (Europass format obligatory). During the registration, applicants will need to prove that they are eligible, according to the ESR definition, mobility criteria, and English language proficiency. The deadline for the on-line registration is 6 October 2019. The Innoveox Recruitment Committee selects between 20 and maximum 30 candidates for the Recruitment Event which will take place in Leuven (21 November 2019).

Funding Notes

The successful candidates will receive an attractive salary in accordance with the MSCA regulations for Early Stage Researchers. The exact (net) salary will be confirmed upon appointment and is dependent on local tax regulations and on the country correction factor (to allow for the difference in cost of living in different EU Member States). The salary includes a living allowance, a mobility allowance and a family allowance (if married). The guaranteed PhD funding is for 36 months.
