“…5). These results are comparable to previous results found to nanofiltration membranes (Alborzfar et al, 1998), with the advantage of using microfiltration and a gravitational system, much more cheaper than a nanofiltration system using pumps. Fig.…”

“…Both methods gave good results; however, NF membranes have several advantages from the point of view of health aspects and lower investment costs. Removal of natural organic matter (NOM) and disinfection by-product (DBP) precursors were also studied [9][10][11][12][13][14][15][16]. Jacangelo et al [11] reported that both RO and NF are used in the US for removal of NOM.…”

“…NF has been widely used in aqueous systems such as water treatment for removal of organic matter [5][6][7], recovery of lactic acid from fermentation broth [8], and concentration of aqueous solutions containing antibiotics [9][10][11][12]. Typically, the nominal molecular weight cut-off of NF membranes ranges from 200 to 1,000.…”

In this study, nanofiltration with NF200 membrane was employed to remove KCl from ion-exchanged solutions containing potassium clavulanate. The pore radius of NF200 membrane was estimated to be around 0.39 nm. The effects of operating pressure on separation performance were investigated in a range of 100-400 psig. The influences of cross-flow velocity (0.14-0.70 cm/s), temperature (4-25 degrees C), and feed composition were also investigated. In all experiments, clavulanate rejection showed high levels from 0.91 to 0.99, while chloride rejection ranged from 0.06 to 0.54. In a case at an operating pressure of 50 psig and 25 degrees C, as much as 94% of clavulanate was retained while 94% of chloride was removed, indicating that NF200 membrane was a suitable choice for selectively removing KCl. NF200 membrane also showed a stable performance in the operational stability test with an ion-exchanged solution obtained by treating actual fermentation broth.
