“…Adsorption is easy to perform, has a high metal-binding capacity, and is functional at a wide pH range [4]. In line with that, the use of these magnetic adsorbents for water purification gives a significant advantage over other adsorbents, such as their low cost and ease of separation of suspending adsorbents to be used again to reduce cost, as well as the ease to synthesize [5].…”

The escalating demand for laundry services, particularly in university districts, has raised concerns about its impact on biodiversity. The situation becomes even more critical when wastewater is discharged into drainage systems without adequate treatment. This study aimed to enhance laundry wastewater treatment by employing ceramic composite beads using ceramic sanitary ware waste and chitosan. The investigation began by characterizing laundry wastewater to identify its specific attributes. Subsequently, the study quantified the removal of zinc as a metal during the laundry wastewater treatment process. Laundry wastewater characteristics were assessed using various parameters, including pH, chemical oxygen demand (COD), total suspended solids (TSS), and turbidity. The result revealed that the treatment of laundry wastewater with ceramic composite beads adsorbent successfully achieved over 50 % reduction in zinc concentration. These findings showed that the ceramic composite bead exhibited an efficiency for metal removal from the laundry wastewater for safe disposal.

“…Recently, the β-cyclodextrin-ethylenediaminetetraacetic acid-chitosan (β-CD-EDTA-CS) polymer was combined with a multifunctional nanohybrid using cross-linking (amindation reaction) (Verma et al, 2022). In another study, nanohybrid beads were produced when graphene oxide (GO) and chitosan (Ch) were modified with iron oxide (Fe 2 O 3 ) nanoparticles (NPs) (Fe 3 O 4 -GO/Ch) via a simple chemical modification (Mishra & Tripathi, 2022). A hydrothermal method is used to synthesize Fe 3 O 4 NPs and with Hummer's method graphene oxide was produced using ferric chloride as the iron precursor.…”

To deal with emergencies like water shortages and water pollution, scientists have worked on making materials and technologies that function well enough. The current technologies are not ‘100%’ efficient at providing potable water. Therefore, it is essential to come up with new and better ways to purify water. Nanotechnology offers inventive water treatment techniques. Nanomaterials are fabricated with useful properties for adsorption, catalysis, sensing, and optoelectronics applications, such as reactivity, high-aspect ratio, controlled pore volume as well as electrostatic, hydrophilic, and hydrophobic interactions. Anions, metal ions, microorganisms, and organic compounds can be eliminated using nanoparticles (NPs). Minimal NP concentrations are required for water treatment, making their application cost-effective. Biopolymeric materials have a number of advantages over their synthetic counterparts due to their easy biodegradability and low impact on the environment. Because of their minimum toxicity, improved adsorption capability, excellent biodegradability, significant photocatalytic potential and biocompatibility, nanobiohybrids have a significant role in the field of water and wastewater treatment. This chapter summarizes various production methods of diversified nanobiohybrids synthesized in recent years, with a particular focus on nanobiocomposites.
