“…Soft, powdered ACs have fewer particles after recycling as it becomes fragmented, whereas harder ACs could be reused several times because the rigid component is well preserved. Granular, powdered and activated carbon fibers are also used for water treatment (Rafique et al 2015(Rafique et al , 2018Rafique and Lee 2014). Compared to granular activated carbon, activated carbon fiber (ACF) and powdered activated carbon is rather soft and difficult to regenerate.…”

Presence of various types of micro-pollutants in domestic, industrial and municipal wastewater and landfill leachates are hazardous for living organisms. Thus, industries need to follow stringent requirements for discharging the chemicals in aquatic system. Organic pollutants, including dyes, hormones, phenols, pharmaceuticals, aromatic compounds, dyes, herbicides, pesticides, bromine containing retardants, industrial by-products, domestic products, sterilisers, and antiseptics, are referred as xenobiotic organic compounds (XOCs). Traditional treatment techniques used for organic pollutant removal is not sufficient. The porous carbonaceous structure of granular (GAC) and powdered (PAC) activate carbon can adsorb targeted pollutants from water. The surface area of activated carbon can be varied from (500-1500 m 2 g −1 ). The first part of the chapter illustrated the basic mechanism for adsorptive removal of contaminants over powdered and granular activated carbon (PAC or GAC). Now a days, adsorption onto activated carbon is integrated with biological process for treating industrial effluents. Adsorption integrated with biological treatment of waste water can be carried out using powdered activated carbon membrane bioreactor (PAC-MBR) and biological activated carbon reactor

Surfactant micelle-assisted removal of ions and organic solutes from aqueous media by micellar enhanced ultrafiltration (MEUF), which is a membrane separation technique, is discussed in detail. Following general information about micellar structure, counterion binding, substrate solubilization, and medium effect functions of micelles which enable separation of cationic or anionic ions and organic molecules from aqueous media by MEUF are explained in a comprehensive manner. Some of the recent studies on removing pollutants from wastewater effluents of industrial plants by MEUF, and their results have been summarized to inform about the factors affecting the removal efficiency of this technique. Methods for recovery of surfactant and contaminants from retentate or permeate solutions are also given. Selective separation of metal ions of the same charge from multicomponent solutions is another topic of this chapter. In this context, the last part of the chapter provides an overview on every aspects of ligand modified MEUF (LM-MEUF) process. This report comprises a comprehensive review of MEUF and LM-MEUF studies in the literature.

“…They used 20 kDa PS membrane and obtained the rejection of more than 99% [53]. Rafique and Lee reported average Cd 2+ removal (74.6%) using PAN membrane [54]. In another study, Rafique et al obtained higher Ni 2+ rejection (83.0%) using membrane MWCO of 300 kDa than that of 100 kDa (72.3%) [55].…”

The pollution of the aquatic ecosystems with heavy metal ions has become a global problem in recent years. Heavy metals normally occur in nature and are essential to life at trace levels. However, they can be toxic when their concentrations exceed the upper permissible limits. Heavy metal contaminated habitats have the ability to bioaccumulate in aquatic ecosystems, which, in turn, may enter into the food chain and lead to health problems. Therefore, it is necessary to remove these heavy metals from aquatic ecosystems. Several technologies are already in operation, but these conventional technologies involve high operational costs and may produce harmful impacts on aquatic ecosystems. Micellar enhanced ultrafiltration (MEUF) is an alternative technique to remove the trace concentrations of heavy metals from aquatic ecosystems. The uniqueness of MEUF is that it requires less energy due to low membrane cost and working pressure. Although various researchers have been carried out the MEUF study on the removal of heavy metal ions, few review papers indicate the factors on MEUF technique. That is the reason why this article focuses on reviewing of different parameters such as membranes, surfactants, operating conditions in the MEUF technique. In this technique, heavy metal ions’ removal even at lower concentrations has reached over 99%, which is evidently demonstrated in the presented review. The use of water-soluble ligands in combination with MEUF is a hybrid process to remove selectively and enhance the recovery of heavy metals. As understood in this study, an investigation is needed to treat highly concentrated solutions and real wastewater.
