The UNSW Centre for Transformational Environmental Technologies (CTET) is an R&D Centre established in December 2017, focusing on the development and commercialisation of innovative environmental technologies. Co-funded by UNSW Sydney and the Yixing Industrial Park for Environmental Science and Technology (ES&TP), the Centre is located in the Jiangsu Innovation Centre of Industrial Technology for Environmental Protection Equipment in Yixing, Wuxi, Jiangsu, China.

Expertise in Environmental Technologies

The Centre currently has more than 20 staff from various cultural background and with a variety of expertise in different areas of environmental technologies including water, air and soil. The Centre offers a suite of advanced water and wastewater treatment technologies and services ranging from low-energy desalination, degradation of toxic organics, low-energy low fouling membrane modules, digital twins of water treatment equipment and Water 4.0 technologies, to performance evaluation, design and optimisation of water and wastewater treatment systems.

The Centre also houses a wide range of state-of-the-art facilities, enabling the development of cutting-edge technologies and commercialisation.

Reactor

Water and Wastewater Treatment

The CTET team has extensive experience in the design and optimisation of both membrane and electrochemical technologies for the treatment of waters and wastewaters. These include membrane capacitive deionisation (MCDI) for desalination of brackish waters and reverse osmosis (RO) for desalination of more saline streams. The team also has wide experience in many aspects of membrane bioreactor (MBR) treatment of wastewaters including optimising coagulant addition, fouling management and energy use minimisation. Innovation in design and operation of advanced oxidation processes (AOP) such as electrochemically-assisted Fenton (E-Fenton) and catalytic ozonation are other areas in which the CTET team are leaders.

Resource Recovery

Recovery of valuable resources from wastewaters and waste solids represents a critical area in need of innovation. CTET, in close collaboration with UNSW Sydney researchers, is involved in early-stage research on use of flow capacitive deionisation (FCDI) for recovery of nitrogen and phosphorus from wastewaters and redox flow battery (RFB) systems for recovery of rare earth elements from wastes. While in the early stages of development, the CTET team are focussed on scale-up of these innovative technologies.
Hydrogen

Air Quality, Human Health and Treatment

Inhalation of airborne contaminants is of concern to all, whether in polluted urban environments or exposed to toxic particulates in the work environment. The CTET team, supported by researchers at UNSW, are developing improved methods to assess the toxicity of respirable particulates high in crystalline silica and bioavailable iron. The CTET team is also developing catalysts for use in household air treatment devices that will ensure the removal of both chemical and biological contaminants.

Contaminated Site Characterisation and Management

Land contamination as a result of both agricultural and industrial activities is a major issue that is being addressed by CTET with support from UNSW Sydney researchers. In particular, R&D on understanding the rate and extent of generation of acidity as a consequence of disturbance of sulfidic soils and sediments as a result of agricultural and mining activities is underway. The CTET team is also examining methods of enhancing the natural attenuation of legacy contaminants present in subsurface environments as a consequence of previous poor industry and waste management practices.

Digital Water Technologies

CTET is very involved in developing AI-based technologies for application in the environmental area. Examples include the development of Digital Twins of our water and wastewater treatment technologies which, when coupled to augmented reality/virtual reality (AR/VR) devices, provide interactive methods to facilitate training of personnel and the development of Smart Twins that incorporate computational fluid dynamics (CFD) and chemical kinetic models. We are also developing machine learning to assist in the design and operation of membrane bioreactors and reverse osmosis plants, particularly in relation to managing fouling and minimising energy consumption. Through our close links with UNSW researchers, we are also using deep learning coupled to X-ray microtomography for 3D mineral characterisation with this information critical to our R&D on acid mine drainage and natural hydrogen generation.

Diagnosis of failure of water treatment plants

Diagnosis of Failure of Water Treatment Plants

Membranes are increasingly applied in a variety of industries, including water and wastewater treatment, food and beverage production and gas refinement, where high throughput and reliable separation are required. Membrane autopsies are an important tool for determining causes of fouling events in membrane systems. When conducting an autopsy it is usually on the premise that the fouling management process has failed and the aim of the autopsy is to identify the root cause of the fouling event and provide some recommendation on how to correct or manage it.
