“…Regardless of the production cycle, it was observed that the concentrations of Ca, Cl, Cr, Fe, K, Mg, S, Si, and Sr in TW (Table 2) were significantly higher than SW and DW, which also exceeded the WHO limits. Huge quantity of different salts, i.e., salts of ammonium, chloride, chromium, and sulfide (Amir et al 2008) is commonly used during the tanning process, which generates trace elements of different concentration in TW. Therefore, an increase in the concentration of Ca, Cl, Cr, Fe, K, Mg, S, Si, and Sr was observed in all TW samples.…”

“…Various chemical analysis techniques such as Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), and synchronous-scan fluorescence (SF) spectra have been used to investigate the composition and changes of DOM during composting (Zbytniewski and Buszewski, 2005;Amir et al, 2008;He et al, 2011). However, the results obtained from the traditional FTIR, NMR, or SF spectra methods may be incorrect because the individual spectral features of FTIR, NMR, or SF often overlap (Yu et al, 2011).…”

“…Assim, várias técnicas de compostagem podem ser utilizadas, dependendo da quantidade de lodo e resíduos a serem tratadas. A compostagem como um método para a gestão de resíduos sólidos de curtume é capaz de evitar muitos dos riscos ambientais e produzir um composto estável, apropriado para a fertilização do solo (Tahiri e De La Guardia, 2009;Amir et al, 2008).…”
