Microfiltration of Concentrated Suspensions of a Microparticulate Ion‐Exchanger Through a Ceramic Membrane

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

“…As known molecules of boric acid B(OH) 3 dissociate in aqueous solution to form tetrahydroxyborate ions B(OH) 4 − as confirmed by Raman spectroscopy [18]:…”

“…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].…”
