Abstract: In this work, column kinetics of Cr(VI) adsorption on autohydrolyzed (160-240 oC, 0-50 min) Scots pine (Pinus sylvestris L.) sawdust were simulated, in order to optimize the potential use of this material for wastewater cleaning. The effect of the autohydrolysis time and temperature on the microstructure and the crystallinity of pine sawdust was investigated be means of SEM, FTIR, XRD and BET. The Modified dose response (MDR) adsorption column capacity q0 increased from 0.6376 to 23.71 mg.g-1, indicating that autohydrolysis treatment at 240 oC for 50 min optimizes the adsorption behavior of the material.

Abstract: The study is focused on providing solutions for the management of water and energetic resources in parkland irrigation networks with the aim of minimizing consumptions originated by their use. An evaluation methodology based on indicators is proposed to assess energetic performance of the system. In the case the system is not managed properly from the energy point of view, an optimization irrigation scheduling by means of genetic algorithms is proposed to improve energy uses. The assessment protocol has been used in the irrigation network of the Universistat Politècnica de València gardens. Results showed that applying this methodology up to a potential saving of 26.8% in energy consumption could be achieved.
