“…The main features of these methods are given in Table 1. The zeta potential can be determined by standard electrokinetic methods such as streaming potential (SP) (10)(11)(12)(13)(14) and electroosmosis measurements (EO) (10,12,(15)(16)(17)(18)(19). Between these two methods, the more widely used procedure is the streaming potential, which has the advantage of being determined during the filtration process.…”

“…The interaction between an electrolyte solution and a charged membrane forms an electrical double layer. The widely used practical and convenient technique to measure the membrane surface charge is the streaming potential (SP) [19][20][21][22][23].…”

“…The SP is generated across the flow path of an electrolyte solution and membrane surface when hydraulic pressure is applied [22]. It can be measured by two different methods, i.e., flow through the pores of a membrane [19][20][21][22]24] or across the membrane surface [23,25].…”

“…It can be measured by two different methods, i.e., flow through the pores of a membrane [19][20][21][22]24] or across the membrane surface [23,25]. Pontié et al [22] discussed the variation of SP across different UF membranes at fixed ionic strength but with variable pressure (0-1.8 bar) and concluded that variations of Áf (electrical potential difference) versus ÁP (transmembrane pressure) are linear with a negative slope (f decreases when P increases). In another study, Pontié et al [24] reported that negatively charged species adsorbed on the membrane increase the surface charge density of the membrane and therefore the SP decreases.…”

A B S T R A C TThe aims of this study were to investigate the fouling mechanisms of model organic compounds (MOCs) on two ultrafiltration membranes [composite regenerated cellulose (YM100) and polyethersulfone (PES)] and the relationship between fouling and membrane characteristics, flux decline, and the streaming potential (SP). Two alginic acids (polymer and dimmer, AA), abietic acid (AbA), colominic acid (CA), and N-acetylneuraminic acid (NA) were selected as MOCs to test their membrane fouling potential through flux decline and SP. The fouling caused by the two AAs, which contained many polysaccharides, was the highest among MOCs, but this fouling was external (solute deposition on the membrane surface) and reversible as polysaccharides did not strongly adsorb onto the YM100 and PES membranes. CA also caused external fouling of the two membranes; however, AbA caused internal (solute adsorption on the pores wall of membrane) and irreversible fouling of the PES membrane. NA, which contained amino sugars, exhibited very low fouling of both membranes. The hydrophilic YM100 membrane experienced less fouling than the hydrophobic PES membrane with all MOCs. The measurement of the SP using a modified dead-end filtration cell was employed to evaluate the flux decline due to MOCs.

“…[16][17][18] Ionic surfactants are often used to charge the discharged filter in a water filtration system to remove the charged particles or ions. Pontiè et al 19 showed that the surface charges on a membrane could be increased by adding ionic or neutral surfactants. Kang and Shah 20 demonstrated that a polypropylene membrane pretreated with dimethyl dioctadecylammonium bromide has a positively charged surface, which removes negatively charged particles.…”

A study of the electrostatic enhancement of collection efficiency of filters pretreated with ionic surfactants has been carried out in controlled conditions with monodisperse aerosols. Cationic surfactant (dimethyl dioctadecylammonium bromide [DDAB]) and anionic surfactant (sodium oleate [SO]) were used to pretreat polypropylene fibrous filters as the positively and negatively charged filters, respectively. The effects of aerosol size, aerosol charge state, face velocity, aerosol type, and relative humidity (RH) were considered to elucidate their influence on the aerosol penetration. Results indicate that penetration through surfactant-pretreated filters was lower than that through untreated filters, and pretreatment of the filter with surfactant was observed not to affect the structure of the filter. The electrofieldmeter direct-measured the very clear electric field of filter when treating ionic surfactants. The results proved that pretreatment with surfactant caused filters to become charged. Comparing penetration through surfactant-pretreated filters with that through untreated filters with neutral aerosol, the penetration reduction factor of the surfactant-pretreated filters was in the range 1.3-2.2. Comparing aerosol penetration through the surfactant-pretreated filters with singly charged aerosol with that through untreated filters with uncharged aerosol indicates that the former decreases by a factor of 1.8 -48.8. The surface fiber charges of the DDAB-and SO-pretreated filters were calculated to be 2.02 ϫ 1 Ϫ10 C/m and Ϫ1.53 ϫ 10 Ϫ10 C/m. Moreover, the aerosol penetrations through the surfactant-pretreated filters increased with the face velocity. Surfactant-pretreated filters performed better against solid aerosol than against liquid aerosol. RH has no effect on aerosol penetration through the surfactant-pretreated filters. Regression equations for Coulombic and dielectrophoretic single-fiber efficiencies in terms of the dimensionless parameters could be fitted by the experimental measurements of surfactantpretreated filters in this work.
