Estudo da cinética de secagem de lodos digeridos provenientes de ETE de indústria de colágeno e gelatina / Study of drying kinetics of digested sludge from a wastewater treatment plant of the collagen and gelatine industry

Abstract: Os lodos de indústria de gelatina apresentam potencial de utilização como biofertilizante, entretanto possuem elevado teor de umidade (98%). Este trabalho objetivou analisar a influência de três diferentes vazões mássicas do ar de secagem (0,3, 0,4 e 0,5 kg.min-1) para uma temperatura fixa de 110ºC na secagem deste lodo em um secador convectivo. Foram utilizados os modelos de Lewis, Page, Henderson e Pabis e Logarítmico para ajuste aos modelos. Os resultados mostraram que, para a menor vazão, o tempo de secage… Show more

“…In this way, the volume of sludge can be significantly reduced and the storage and transportation costs are correspondingly lowered. More importantly, the dewatered sludge is prone to achieve a safe and stable state without odor and pathogenic organisms. , Consequently, developing efficient technology for drying sludges is of great significance to sustainable development and a friendly living environment.…”
