“…Specifically, the objective function (Ф) was expressed as: (17) where h, l and n respectively represent the number of experimental data recorded in each experiment, the number of the reacting species, and the number of experiment used in the optimization procedure. The percentage standard deviation on the i th species was calculated as follows: (18) where represents the average measured concentration of the i th species and p the number of the unknown parameters to be estimated. In this case, p = 1, since k HO/BP was the only unknown parameter.…”

RESUMO:O presente trabalho avaliou as condições de reúso dos efluentes finais de dois sistemas de tratamento biológico de esgotos: um reator UASB e um sistema de lodo ativado frente aos padrões recomendados da Organização Mundial de Saúde (OMS) e os critérios de qualidade de água para irrigação. As variáveis avaliadas foram pH; CE; Ca 2+ ; Mg 2+ ; Na + ; Cl -; NTK; Fósforo total; DQO; Turbidez; SST; amônia; coliformes termotolerantes e ovos de helmintos; RAS; e salinidade. Os resultados demonstraram que os sistemas só cumprem parcialmente os requisitos para reúso agrícola. O sistema UASB apresentou SST e turbidez como limitantes na irrigação localizada, concentração de coliformes apenas para irrigação restrita em subsuperfície, NTK acima de 30 mg.L -1 e a contagem > 1,0 ovo.L -1 de helmintos que inviabiliza o reúso. O sistema UCT apresentou menos limitações de acordo com os parâmetros avaliados, com inviabilidade de reúso direto principalmente devido à turbidez, coliformes e ovos de helmintos.

“…Such plantations are becoming feasible through modern desalination (Khawaji et al, 2008;Fritzmann et al, 2007), wastewater (Hamilton et al, 2007;Oron et al, 1999), and irrigation techniques (e.g., see Spreer et al 2007). Valuable and hardy shrubs such as Jatropha curcas (jatropha) or Simmondsia chinensis (jojoba) can withstand heat and drought, and be irrigated with waste-or brackish water (Rajaona et al, 2012;Abou Kheira and Atta, 2009;Benzioni, 1995).…”

Abstract.A 10 × 10 km irrigated biomass plantation was simulated in an arid region of Israel to simulate diurnal energy balances during the summer of 2012 (JJA). The goal is to examine daytime horizontal flux gradients between plantation and desert. Simulations were carried out within the coupled WRF-NOAH atmosphere/land surface model. MODIS land surface data was adjusted by prescribing tailored land surface and soil/plant parameters, and by adding a controllable sub-surface irrigation scheme to NOAH. Two model cases studies were compared -Impact and Control. Impact simulates the irrigated plantation. Control simulates the existing land surface, where the predominant land surface is bare desert soil. Central to the study is parameter validation against land surface observations from a desert site and from a 400 ha Simmondsia chinensis (jojoba) plantation. Control was validated with desert observations, and Impact with Jojoba observations. Model evapotranspiration was validated with two Penman-Monteith estimates based on the observations. Control simulates daytime desert conditions with a maximum deviation for surface 2 m air temperatures (T 2) of 0. and are at least 100-110 W m −2 higher than the surrounding desert. This surplus is driven by reduced albedo and high surface resistance, and demonstrates that high evaporation rates may not occur over Jojoba if irrigation is optimized. Furthermore, increased daytime T 2 over plantations highlight the need for hourly as well as daily mean statistics. Daily mean statistics alone may imply an overall cooling effect due to surplus nocturnal cooling, when in fact a daytime warming effect is observed.
