Small scale photoelectrocatalytic system for advanced drinking water treatment (PhD research project)

The focus is to design a PEC reactor for removal of organic Contaminants of Emerging Concern (CECs) from drinking water for small scale systems, particularly suitable for remote areas…

Details

The aim of this research is to develop a small scale Photoelectrocatalytic (PEC) system. The research will target removal of emerging contaminants with potential application to direct potable reuse schemes. The goal of this study is to provide safe drinking water, especially in areas where no advanced treatment systems are in place and for rainwater systems. The work is aligned with the Australian Drinking Water Guidelines, which encourages investigative studies for validation of processes and design of equipment, as well as the continuous improvements and applied research and development to be directed towards investigating improvements, new processes, emerging water quality issues and new analytical methods; validation of operational effectiveness of new products and processes; increasing the understanding of the relationship between public health outcomes and water quality. This is aligned with several of the UN Sustainable Development Goals (SDG30), including providing safe drinking water and good health and wellbeing.

PEC systems for drinking water treatment are found in lab-scale, operating in batch mode and are not yet commercially available. Major areas for development include developing design criteria; improve electrodes stability; optimize energy consumption; reduce capital investment; and investigate intermediate products formation. The development of an effective treatment system requires a comprehensive understanding of the process principles and mechanisms, as well as the optimization of components’ features and operating conditions.

The project will take an engineering approach for the PEC reactor design starting from the investigation of state of art (in terms of components) and operational conditions of existing systems; set a baseline for the system design; perform preliminary calculations and purpose system geometrical concepts; search for material and manufacturing techniques availability; validate calculations and prepare engineering drawings for PEC reactor development. The design concept combines minimum mass-transfer limitations, maximum photon capture and minimal resistance between electrodes.

Advances in the light sources will allow the use of a high-power LED-UV at required wavelengths, minimizing the energy consumption when compared to vapor lamps. Tests with target compounds will assess the system’s performance by analysing contaminant removal rates results, optimization of operational parameters, validation of design and investigation of intermediate products formation.
