Abstract

The contamination of water from dye industries is considered one of the most global urgent concerns as it compromises the esthetic feature of water bodies, inhibits plant growth, and might stimulate toxicity and carcinogenicity. Adsorptive membranes are highly viewed as one of the prospective technologies that have demonstrated competency in wastewater treatment due to their capacity to make wastewater clean enough for reuse. The adsorption mechanism that lies between adsorptive membranes and dye molecules depends on the individual properties and characteristics. Novel hybrid composite membranes with organic/inorganic additives have been considered for adsorptive membranes as they are expected to advance the effectual removal of dyes from wastewater. The impact of organic/inorganic additives on hybrid adsorptive membranes is highlighted based on the bulk polymer properties like mechanical and chemical resistance together with the structural configurations of the membrane. As such, it is important to understand the interaction mechanisms between adsorbents and dyes for effectual removal of dyes from wastewater. Here, we review the governing interaction mechanisms between dye and adsorptive membrane in the membrane separation process together with the modified adsorptive membranes. Despite the fact that adsorptive membranes possess outstanding effectiveness and capability in wastewater treatment for reuse which provides them a great chance to be employed as prospective technologies for dye adsorption; adsorptive membranes are still racked with some drawbacks. Hence, we present different modification methods used in combating these drawbacks which will subsequently improve the performance of adsorptive membranes.
