The Faculty of Physical and Chemical Engineering successfully organized a mini international workshop on advanced water treatment technologies

On the 1st November, the Faculty of Physical and Chemical Engineering (FPCE) organized a mini international workshop on green technologies for water treatment and air pollution mitigation. The workshop was chaired by Assoc. Prof. Cao Hai Thuong, vice-dean of the FPCE and Dr. Vu Dinh Thao, head of the Environmental Engineering School. Attending the workshop were Prof. Long Nghiem from University of Technology Sydney, Assoc. Prof. Nghiem Trung Dung from Hanoi University of Science and Technology, Dr. Tran Thi Thu Lan from Institute of Environmental Engineering, Vietnam Academy of Science and Technology and lecturers of the FPCE.

At the workshop, Prof. Long Nghiem had an informative and interesting presentation on advanced and green water treatment technologies destined for the 4th generation revolution. These technologies are based on various membrane processes that simultaneously enable the treatment of wastewaters, recovery of nutrient and minerals from wastewater, and production of green energy. According to Prof. Long Nghiem, given the opportunities of the 4th generation revolution, wastewater is no longer wastewater, but great sources of valuable nutrients, minerals, and energy. With their distinct separation characterizations, the membrane processes can separate fresh water, extract nutrients and minerals from wastewater, and turn their chemical potential into green energy. The future wastewater treatment plants equipped with the modern membrane processes will be not only for wastewater treatment, but also to produce fertilizers, minerals, and energy.

During his presentation, Prof. Long Nghiem also introduced one of his recently launched water treatment projects in Hanoi. This project is funded by the Australian government via the Aus4Innovation program, and aimed at providing a smart, robust, and cost-effective technology to treat ground and surface water heavily contaminated with ammonia and arsenic for drinking water. Within the intended framework of the project, a smart, integrated water treatment system with the capacity of 10 m3 of drinking water per day will be constructed and trialed at Tien Phong Primary School at Thuong Tin, Hanoi. This system combines conventional pre-treatment methods with a catalytic advanced oxidation process for improved ammonia and arsenic removal, thus enabling the effective treatment of the heavily polluted ground and surface water at Tien Phong Primary School. The water treatment system is also equipped with smart sensors and Internet of things (IoT), rendering it a typical water treatment technology of the Industry 4.0. Given its advanced technology, the water treatment system is expected to provide high quality drinking water to not only teachers and pupils of the Tien Phong Primary School, but also the neighboring communities.
Following Prof. Long Nghiem, Assoc. Prof. Nghiem Trung Dung delivered a short talk on air quality and air pollution of Hanoi. Recently, air pollution has been a burning issue for Vietnam in general, and Hanoi in particular. Assoc. Prof. Dung’s talk shed light on the degraded air quality in Hanoi, the causes of air pollution, and viability of air pollution management and control strategies. Particularly, Assoc. Prof. Dung pointed out the major cause of the worsening air quality in Hanoi, attributing the recent burning air pollution issue to the overuse of personal transportation means such as cars and motorbikes. To conclude his talk, Assoc. Prof. Dung strongly recommended and urged people in big cities like Hanoi and Ho Chi Minh to use more public transport to mitigate air pollution.
The workshop ended up with open discussions on current and future research collaboration among the FPCE (Le Quy Don Technical University), the Center for Water Treatment Technology (University of Technology Sydney), School of Environmental Science and Technology (Hanoi University of Science and Technology), and Institute of Environmental Engineering (Vietnam Academy of Science and Technology). The workshop, as concluded by Assoc. Prof. Cao Hai Thuong, was a significant event for the lecturers and staff of Physico-Chemical Engineering Faculty to build up and facilitate their research momentum, particularly in the context of the 4th generation revolution.
