TAIPEI (Taiwan News) – AU Optronics Corp. (AUO) announced Wednesday that its process water full-recycling system, the first of its kind developed in Taiwan, was launched at the Company’s Lungtan site.

“AUO has made a technological breakthrough in process water recycling,” it said.

By going through various recycling phases, process water could be condensed and reduced by 98 percent, and then zero liquid discharge is realized by using high efficiency evaporation equipment, the company said.

AUO also pledged that by year 2020, it will achieve three major water resource goals, namely “Water Reduction, Water Creation & Water Replenishment”. The goals are: TFT-LCD production water intensity will be reduced by 30 percent, 10,000 tons of reclaimed water will be used daily at AUO’s Taichung site, and water neutrality will be achieved at AUO’s Lungtan site. Proactive and forward-looking water resource development strategies will be deployed to ensure sustainable development for the environment.

“Under the increasingly extreme weather conditions, risks caused by water shortage present challenge and crises. However, through technological advancements in green and water resource management, AUO continues to create new values and opportunities on the path to sustainability,” Paul SL Peng said, AUO’s chairman and chief executive officer.

Premier Mao Chi-kuo, while attending the event, also acknowledged AUO’s long-term dedication to the research and development of water-saving technologies, and subsequently the successful launch of the process water full-recycling system. AUO, capable of balancing both business development and environmental protection, sets an example for the sector.

AUO started the research and development of process water recycling in 2010, and had worked with Industrial Technology Research Institute of Taiwan (ITRI) for a year on partial technologies involved. Later, its self-designed system and construction plan was proposed, and initiated the three-year construction of process water full-recycling system in 2013.

“The system officially was launched in year-end, setting a successful example for independent system design and integration achieved by local teams,” AUO said.

The process water full-recycling system at AUO’s Lungtan site uses membrane bioreactor (MBR), reverse osmosis (RO), electrodialysis reversal (EDR), and evaporator (EVP) during the various phases of water recycling and reusing to achieve zero liquid discharge. Meanwhile, by leveraging optimized and integrated design, AUO’s process water full-recycling system could significantly reduce energy use and sludge, which is an advanced and environmentally-friendly water resource recycling solution available in the manufacturing sector.
