Viet NamNews reports that some 150 scientists gathered in Hà Nội to discuss how to develop environmentally friendly, economically viable and energy efficient processes to treat and preserve the world’s limited water resources.

The three-day conference on Green Technologies for Sustainable Water 2017 (GTSW) was organized by five universities – the University of Technology Sydney, University of Wollongong, Tianjin Polytechnic University, Việt Nam’s University of Science and Việt Nam-Japan University (VJU).

Speaking at the opening ceremony, VJU rector Furuta Motoo said the development of environment-friendly technologies for water resource utilization and management is of vital importance in the context of population growth. With global water resources being gradually depleted, especially for countries strongly affected by climate change like Việt Nam, demand risks exceeding supply.

“There is an urgent need to exploit and develop appropriate green technologies that promote design, production and supply chain because the major cause of the world’s water shortage and continued environmental deterioration is the unsustainable, unregulated pattern of consumption and production,” said Executive chair of the GTSW 2017 conference, Ngô Hữu Hào.

The limitations on the amount of fresh water from natural sources forced the water industry to expand supplementary sources, such as rainwater, storm water, desalinated water or recycled water, which in most cases need extensive treatment to ensure human health and environmental safety, he added.

Professor Ashok Pandey from India’s Centre of Innovative and Applied Bioprocessing, one of the 150 scientists participating in the conference, presented microalgae-based research, which he said has extensively progressed for the production of value added products and biofuels.

“Coupling mass cultivation of microalgae along with industrial waste waters, seawater with industrial waste carbon sources seems to be beneficial for minimizing the use of fresh water, reducing carbon, nutrient cost and producing algal biomass as resources for biofuels and other high commercial value metabolities,” he said.
