Microfiltration of suspensions of microparticulate boron adsorbent through a ceramic membrane

Cross-flow microfiltration of fermentation broth containing native corn starch

“…The significant advantage of this model is that it accounts for different fouling phenomena governing the membrane blocking at the initial and advanced phases. This model has been successfully used to characterize MF performance of a solution containing bovine serum albumin [29], humic acid [28], microparticulate boron adsorbent [30], extracellular polymeric substances [31] and ultrafiltration of natural organic matter [32]. According to this model, the rate of change of the cake layer resistance is proportional to the rate of change of the cake mass deposited over the membrane surface:…”

Integrated solution for boron removal from seawater using RO process and sorption-membrane filtration hybrid method

“…The more extensive studies on the use of submerged membrane modules were conducted by Schlosser et al [30][31][32]. The authors found that the suspension of the same particles as applied at our study can be concentrated in microfiltration unit up to 24 mass%.…”

Microfiltration of micro-sized suspensions of boron-selective resin with PVDF membranes

“…This reduces the amount of the sorbent required and decreases the operating costs of the water deboronization. It was also reported [18], [19] and [20] that the consumption of chemicals and energy with AMF are much lower compare to fixed-bed ion exchange treatment. Although numerous papers have been published on the AMF process [11], [12], [13], [14], [15], [16], [17], [18] and [19] they focused mainly at efficiency of boron removal with the boron-selective resins from different feeds, however the studies on how membrane pore size, pH and ionic strength of the feed affect the membrane flux and separation of boron-saturated resins are still rare [20] and [21].…”

Ondercova et al [20] and Blahusiak at al. [21] used the tubular ceramic membranes of 0.1 μm pore size to simulate and concentrate suspensions of Dowex XUS resin with the mean particle size of 4.7 μm at suspension concentrations of 0.0015 to 20 wt.%, and different crossflow velocities and operating pressures.…”
