The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (th ....The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (the fibres from skins) to overcome this problem, and it will also be possible to dry sticky materials using material from the fruit itself, rather than additives such as maltodextrin.Read moreRead less
Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams ....Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams will enhance the health of receiving water bodies and reduce the risk of increased build up of contaminants if wastes are recycled into wastewater treatment plants. New ways to treat such contaminants will be explored, the efficiency and cost evaluated in the broader water cycle and sustainability framework.Read moreRead less
Flotation separation of nanoparticles. This project deals with the separation of fine nanoparticles suspended in water, by attachment to small gas bubbles. It aims to find a way of removing nanoparticles from water, or of separating one species from another. The process could be used for simple solids such as metal oxides, and for biological materials such as large molecules, viruses and small bacteria. The work will be both theoretical and experimental. This ground-breaking project will build u ....Flotation separation of nanoparticles.

Innovative strategy for salt management and water recovery from newsprint mill effluent using membrane processes. Newsprint mills are a major employer in regional Australia. The mills are located in environmentally sensitive areas, consume large quantities of water and return high levels of salt to the environment. To remain competitive the newsprint industry, like all industries in regional Australia must develop new strategies for water recycling and salt management.

Newsprint mills are a major employer in regional Australia. The mills are located in environmentally sensitive areas, consume large quantities of water and return high levels of salt to the environment. To remain competitive the newsprint industry, like all industries in regional Australia must develop new strategies for water recycling and salt management. Successful execution of this project will minimize water consumption in newsprint production, mitigate the effects of increased sodicity in soils irrigated with mill effluent and accelerate the commercial development a hydrophobic microporous membrane for water recycling and salt removal in environmentally sensitive areas of inland Australia.Read moreRead less
