Hao, Xiaodi (author), Wu, Daoqi (author), Li, Ji (author), Liu, Ranbin (author), van Loosdrecht, Mark C.M. (author)Entropy is a concept defined by the second law of thermodynamics. Applying this concept to the world we live in, entropy production must be minimized and negentropy (negative entropy production) should be accelerated, in order to produce a healthy and stable ecological system. The present wastewater treatment, however, contributes to entropy...journal article 2022
