Removal of sodium dodecyl benzene sulfonate and phenol from water by a combined PAC adsorption and cross‐flow microfiltration process

Highly mesoporous K2CO3 and KOH/activated carbon for SDBS removal from water samples: Batch and fixed-bed column adsorption process

“…These results are supportable due to the mesopores percentage in Table 4. Because the AC prepared by K 2 CO 3 with impregnation ratio of 0.75 wt% has the highest percentage of mesopores, which, due of the relatively high molecular weight of SDBS (349 g/mol) and slow transfer rate of SDBS to AC powder and granule (Juang et al, 2004), the dominance of the mesopores, gives more space available for adsorption of SDBS to the pores of the adsorbent. As mentioned before, the excessive use of K 2 CO 3 and KOH as AAs results too much cavity and lead to cracks formation, due to an increased production of species of K, K 2 O, CO and CO 2 , and their removal in the washing step becoming difficult, therefore decreasing the specific surface area and adsorption capacity.…”

Improvement of wine crossflow microfiltration by a new hybrid process

“…adsorption and membrane separation, alone (Konieczny & Klomfas, 2002;Mavrova, Erwea, Blocher, & Chmiel, 2003;Roux, Krieg, Yeates, & Breytenbach, 2005). A hybrid process can be applied to fields such as gas separation, biosorption and the removal of heavy metal from wastewater (Juang, Lee, & Chen, 2004;Kwang-Sup, Joo-Heon, Dong-Ho, Seok-Joong, & Soon-Dong, 2004;Reddad, Gerente, Andres, Thibault, & Cloirec, 2003;Zhang, Li, Benjamin, & Chang, 2003). The main advantage of this type of hybrid process is a high yield combined with high separation efficiency.…”

Removal of soluble organics from water by a hybrid process of clay adsorption and membrane filtration

“…For the removal of trace levels of dissolved organics such as methanol, ethanol, carbon tetrachloride, and phenols from water, the membrane processes are efficient only when the membranes have a smaller MWCO such as RO and NF. However, the removal can be alternatively achieved using the membranes with a large MWCO such as UF and MF when they are combined with an adsorption process [2][3][4][5][6][7]. The basic idea is that the organics can be retained by membranes after the organics are fully adsorbed on the common powder adsorbents.…”

“…This may result from the reduced organic loading to the adsorption of humic substances on PAC. Juang et al [4] have removed sodium dodecyl benzene sulfonate and phenol from water by a combined PAC adsorption and cross-flow MF process. More than 90% of the organics was removed when the PAC dose was beyond 0.8 g/L.…”
