摘要：

Due to many factors such as the global warming and the population growth, sustainable production of fertilizer is an important subject. In that respect, water management has a strong impact when phosphoric acid production is considered. Water consumption greatly varies according to the process chosen and the quality of water available. Water consumption comparison between hemihydrate, dihydrate and the new dihydrate hemihydrate DA-HF process will be presented. From the results shown, some possible paths are presented to reduce the water consumption. (C) 2016 The Authors. Published by Elsevier Ltd.
