December has came. We are at the end of 2017 and the new year is just around the corner. The third quarter in Nagasaki University has ended and the fourth one has already began. The weather is cold as usual, but we are used to it now, I guess. Last week, we joined the observation trip to Mamizu Pia and Yamanota Purification Treatment Plant. There are so many things I could learn from there, especially about their modern technologies, which is far more advance than in my country. In Mamizupia, they use ultrafiltration and reverse osmosis technologies to desalinate seawater in order to get the fresh one while Yamanota plant uses ceramic membranes. Both systems are very well organized and operated. The plant staff invited us to try the treated water and half of us could not distinguish it from the tap water. It is demonstrated how far Japan has gone in terms of wastewater treatment. I am looking forward to learning from them. ^_^
