“…2(d), when AS used alone, zeta potential improved as the aluminum dosage increased and the maximum value was −4.9 mV, which indicated that charge neutralization played a role in the coagulation process. Since the synthetic test water was alkaline (pH 8.18-8.45), significant precipitation of amorphous hydroxide could occur, and charge neutralization was achieved by adsorbed precipitation [28,29]. When Pa was added, zeta potential drastically increased.…”

“…Para minimizar os efeitos negativos do aspecto da água no decorrer dos processos, algumas indústrias de processamento de maçãs adotam sistemas convencionais de filtração e de desinfecção, usando cloro ativo. Contudo, esses sistemas de filtração são ineficientes para a remoção de material coloidal e de matéria orgânica natural, como substâncias húmicas (MATILAINEN; VEPSÄLÄINEN; SILLANPÄÄ, 2010; SÄRKKÄ; VEPSÄLÄINEN; SILLANPÄÄ, 2015), que reagem quimicamente com o cloro ativo podendo levar a formação de substâncias cancerígenas (CHENG et al, 2003;SÄRKKÄ;SILLANPÄÄ, 2015;WANG et al, 2016;WENG et al, 2006;XIAO et al, 2014).…”
