“…A aglutinação dessas partículas desestabilizadas pelos hidróxidos metálicos proporcionou então, a formação dos flocos. Simultaneamente, as microbolhas de gás oxigênio geradas no ânodo e de gás hidrogênio geradas no cátodo, formadas pela hidrólise da água, ascenderam à superfície por eletroflotação, carregando por arraste, os flocos formados, promovendo assim, a remoção dos poluentes (CAN, 2014;XU et al, 2015) …”

“…It has been proved that pretreatment (such as adsorption, coagulation or peroxidation) can remarkably reduce improve membrane performance by achieving larger permeate flux in combined water treatment systems, in which coagulation has been proved to be more effective than the other pretreatments in reduction of membrane fouling [10]. Breakthroughs have been made by previous researches in all aspect of C-UF system, including influence of coagulants/flocculants by Xu et al and Zhao et al [11,12]; optimization of operating conditions in application of C-UF in drinking water treatment and pilot-scale hybrid municipal wastewater reclamation [13,14]. Therefore, coagulation-ultrafiltration hybrid process (C-UF) is becoming more and more popular in high quality water treatment processes for its high removal efficiency of NOM.…”

“…The study shows that the flow reduction for conventional coagulation/ultrafiltration systems using aluminium coagulation is 52% approx., while the addition of polydimethyldiallylammonium chloride reduces this flow loss to 34% for ultrafiltration membranes with a MWCO of 100kDa [12]. …”

“…Xu et al (2015) [12] conducted a study with synthetic waters on the impact of organic coagulant aid on purification performance and membrane fouling in a coagulation/ultrafiltration hybrid process. conducted a study with natural waters from a river in Brazil using coagulation/flocculation/ultrafiltration systems with ceramic membranes, observing that surface water coagulated with aluminium sulfate produced less membrane fouling than natural waters or those coagulated with chitosan [15].…”
