Background data on solar heat-assisted stripping-absorption system for ammonia recovery from food waste digestate

The data presented in this paper are related to the research article "Ammonia recovery from food waste digestate using solar heat-assisted stripping-absorption" [1]. The raw and filtered data are associated to daily monitoring of NH₄ concentration of food waste digestate, pH of digestate and absorption solution and temperature of food waste digestate throughout experiments at different conditions. In addition, data of temperature monitoring in different points of solar-heat assisted stripping-absorption device are presented. The data could help further studies aiming to improve this system. The detailed data of these experiments could help to improve the performance and to reduce costs of nitrogen recovery from digestate using stripping-absorption technology.
