Professor Fallowfield is an aquatic microbial ecologist. His research focus is health aspects of water quality, which has been conducted across a range of aquatic environments including drinking water, wastewater and recreational waters. Howard has some 25 year's research experience in the UK and Australia, designing, constructing, operating and evaluating the performance of pilot plants for both drinking water and wastewater treatment. Successful research projects include the design and operation of high rate algal ponds (HRAPs) for the treatment of abattoir wastewater; construction and evaluation of new HRAP designs for the treatment of wastewater from rural communities in South Australia. The application of HRAPs for the treatment of wastewaters and on-site biomass energy production is also a current research project. A further research interest is the remediation of drinking water and groundwater contaminated with inorganic nitrogen, pharmaceuticals and personal care products using biological filters.
In 2017 I was a member of the Environmental Health Team, with Dr Kirstin Ross and Dr Harriet Whiley, presented with the Vice Chancellor's Award for Excellence in Teaching
Within the College of Science and Engineering Prof. Fallowfield is coordinator of Research Higher Degrees associated with environmental sciences and the Health and Environment Group.
My research focusses on exploiting aquatic microbial ecology for the treatment of drinking water and wastewater. I have significant experience in both UK and Australia, designing, constructing, operating and evaluating the performance of lagoon systems (including waste stabilisation ponds and high rate algal ponds - HRAPs) for the treatment of domestic and agri-food wastewaters. Much of the research is conducted at pilot-demonstration scale. Our research on the performance of two HRAPs treating wastewater in a rural South Australian community, following independent validation, lead to regulatory approval and wider adoption of this sustainable technology in South Australia. The HRAP research has recently extended to the integration of treatment and sustainable on-site algal biomass energy production and to the managment of risk associated with treated wastewater reuse for agriculture in the Asia-Pacific region. Understanding the influence of operational and environmental parameters on the mechanisms for the removal of mrobial pathogens in treatment systems is of particular interest.
Integrated anaerobic-aerobic and algal treatment of piggery wastewaters is also a current area of research using a purpose built pilot scale treatment system funded via membership of the High Integrity Australian Pork CRC.
This expertise is recognised internationally through membership of the Scientific Organising Committee for five of the International Water Association's Specialist Group Conference on Wastewater Pond Technologies and as Chair of the Organising Committee for the 9th specialist conference held in Adelaide in 2011. The HRAP research is also supporting the implementation of the WHO Sanitation Planning Manual through contribution to the Global Water Pathogen Project.
My group also conducts research on the performance of constructed wetlands integrated with Managed Aquifer Recharge Schemes. The focus is on the removal of microorganisms, phamaceuticals and personal care products by these integrated systems.
My contribution to teaching reflects my expertise and interest in microbial ecology, particularly of aquatic environments, which have the potential to influence human health. Water quality and the treatment of wastewater, drinking water and stormwater is a specific focus together with the eutrophication of freshwater and the impact and management of cyanobacterial blooms.
I am a member of the International Water Association and its Specialist Group on Wastewater Pond Technologies; the Society for Applied Microbiology and of the High Integrity Australian Pork Co-operative Research Centre. Previous research assessing microbial risks associated with recreational waters was recognised by membership of National Health and Medical Research Council committee which reviewed Guidelines for Managing Risks in Recreational Waters.
I am a reviewer for several international journals including Water Research, Journal of Applied Microbiology, Applied Phycology, Water Science and Technology.
I am a co-editor of the textbook Environmental Health in Australia and New Zealand published by Oxford University Press.
I have authored over 160 articles in peer reviewed journal and conference proceedings. Current research on high rate algal ponds is a collaboration with District Councils and the Local Government Association aimed at adopting the technology for use in rural communities in South Australia, however, the technology would also be appropriate for rural communities nationally and in developing countries. Integrated wastewater treatment technologies are also being investigated to enhance the sustainability and international competitiveness of Australian pork producers through membership of the High Integrity Australian Pork CRC.
