In the present study, a combined approach of ozone-based advanced oxidation and adsorption by activated char was employed for the treatment of a pharmaceutical industrial effluent. Ozone is a selective oxidant, but the addition of H 2 O 2 generated in situ hydroxyl radicals, which is a non-selective stronger oxidant than ozone. The effluent obtained from the pharmaceutical industry mainly contained anti-cancer drugs, anti-psychotic drugs, and some pain killers. The peroxone process had 75–88.5% chemical oxygen demand (COD) reduction efficiency at pH 5–11 in 3 h. Adsorption by activated char further reduced the COD to 85.4–92.7% for pH 5–11 in 2.5 h. All other water quality parameters were significantly decreased (>73% removal) during ozonation. The primary operational parameters (system pH and H 2 O 2 concentration) were also varied, and their effects were analyzed. The pseudo-first-order rate constants for ozonation were calculated, and they were found to be in the range of 1.42 × 10 –4 to 3.35 × 10 –4 s –1 for pH 5–11. The kinetic parameters for adsorption were calculated for the pseudo-first-order, pseudo-second-order, and Elovich models. The fit of the pseudo-first-order kinetic model to the experimental data was the best.

“…Pharmaceutical trade industries generate a massive variety of constituents by utilizing inorganic and organic combinations as raw sources thus increase in enormous size of poisonous and multifaceted organic liquescent wastes contained greater intensities of mixed solids. Large and reduced power wastewater creeks initiated from industrial unit frequently comprises various kinds of contaminants, counting organic combinations [13]. Furthermore, numerous kinds of wastewater feature from the pharmaceutical industries vary critically, many categories of pharmaceutical wastewater are resilient to biodegradation, have greater nitrogen in ammonia amounts, color depth and toxicity; and are hard to handle [56].…”

“…Furthermore, different groupings of traditional wastewater treatment procedures have been applied, for instance chemical and physical approaches (advanced oxidation routes, chemical treatments, adsorption, filtration, and coagulation) besides joined biological courses for the handling of pharmaceutical wastewater. Ultimately, all these systems have different COD elimination capacities, contingent to the kind and organic capacity of the wastewater [13].…”

In recent years, the pharmaceutical field has significantly achieved magnificent progress owing to the necessities of human health and life; however, it also led to drastic environmental issues. The existence of pharmaceuticals in water bodies, which could cause adverse effects on human beings and environment, rose up distress worldwide. The pharmaceutical components found in water bodies have mainly two origins: manufacturing procedures in pharmaceutical industry and common usage of pharmaceutics. The essence of pharmaceutical wastewater (PWW) is intricate, including large amount of organic matter, high salt, microbial toxicity, and non-biodegradable. In sight of water scarcity means, it is essential to figure out and expand techniques for pharmaceutics derived wastewater in water management. Nevertheless, numerous treatment methods have been established to serve pharmaceutical wastewater including biological treatments, membrane technologies, hybrid technologies, advanced oxidation processes, absorption methods, etc. Recently, metal organic frameworks (MOFs), metallic ions clusters linked with organic bridging linkers, have been utilized in number of uses such as storage, separation, sensing, catalysis, adsorption, and many others. The viability of MOFs toward wastewater treatment (WWT) for various pollutants is fundamentally because of the extreme porosity, discrete pore structure, and superficial modification. This chapter highlights the origin and treatment of pharmaceutical wastewaters via the utilization of MOFs and their hybrid systems. A brief perception of the future work in the field has also been discussed.

“…As presented in the previous sections, the technical performance of the application of ionizing radiation technology in wastewater treatment is effective in disinfection and reduces the bio-refractory nature of several persistence organic pollutants. Several studies proved the economical feasibility of the e-beam and γ irradiation technologies [21,32,41,48,51,[54][55][56][57][58][59][60][61][62][63]. For e-beam technology, the capital costs include the accelerator price, building shield, conveyer, cooling and ventilation systems, and monitoring system [57].…”
