“…Additionally, biological systems can be more effective in terms of removing organic matter in wastewater from the pharmaceutical industry when compared to studies where coagulation is used, and the removal of COD was only 49 % [35,36]. Other authors apply for treatment of pharmaceutical industry wastewater a combination into electrocoagulation, electro-Fenton, and photocatalytic oxidation, where the effective remotion was observed 64 % total organic carbon and 70.2 % COD [37]; for remotion of 99 % COD in wastewater pharmaceutical industry combination between micro-electrolysis and Fenton oxidation-coagulation, this study needed 90 days to almost remove COD wholly [38]. In the future, a possible combination of physicochemical technologies with a biological treatment could reduce the time of COD remotion and additionally remove Emerging Pollutants in wastewater.…”

The impact of non-domestic wastewater (nDWW) on water bodies every day is increased, considering the different pollutants that are entering and these are not regulated, also that the effects of these are not known in the ecosystems. In the case of the pharmaceutical industry, the various products they generate can contribute from non-steroidal anti-inflammatory analgesics (NSAIDs), antihypertensives, hormones, antibiotics, among others; they are being detected in surface waters and it is necessary to create strategies to improve treatment systems and thus reduce their effects on water systems. In this work, the native microorganisms from nDWW of the pharmaceutical industry were used to evaluate their ability to influence the removal of organic matter, working in mixed culture, where it was evidenced that in a 24 hours they could remove 45.82 % of the organic matter measured by the chemical oxygen demand (COD) and at 48 hours 90.59 % removal. The above shows that the use of microorganisms can contribute to the reduction of COD and pollutants in an effective, environmentally friendly and, more efficient way than conventional methods. Besides, the qualities of tolerance to four NSAIDs by 16 morphotypes are evidenced, and how they can be profiled in the future to be potentialized and reach the mineralization of these emerging pharmaceutical pollutants.

“…PWW, chiefly chemical pharmaceutical wastewater, has now converted into most hard-to-manage and risky categories of wastewater [39]. Pharmaceutical wastewater possesses small amount of biochemical oxygen demand (BOD) and greater concentration of chemical oxygen demand (COD) in pharmaceutical wastewater [8].…”

“…In a study, the pharmaceutical treatment was evaluated by grouping of photocatalytic oxidation (PcO), electroFenton (EF), and electrocoagulation (EC) procedures. Furthermore, the effect of procedure order and reaction duration, current concentration for EF and EC procedures utilizing iron plate electrodes and lastly photocatalytic action of various catalysts for PcO procedure were inspected in order to remove total organic carbon [8].…”

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.

“…Además, los procesos de elaboración de estas sustancias son llevados a cabo por lotes, situación que da como resultado aguas residuales de composición compleja y fuertes fluctuaciones en la concentración de contaminantes (Ling et al, 2020). La baja biodegradabilidad de estos productos hace que las aguas residuales que los contienen presenten bajos valores de DBO y altos valores de DQO, lo cual representa un inconveniente para el tratamiento biológico de dichas aguas, puesto que los compuestos químicos recalcitrantes pueden restringir la actividad de los microorganismos (Başaran-Dindaş et al, 2020). De esta manera, las aguas residuales generadas por las empresas farmacéuticas tienden a ser refractarias a la mayoría de las técnicas de tratamiento físico, químico y biológico convencionales.…”

El presente trabajo fue realizado con el fin de mejorar el desempeño de un sistema de ozonización utilizado para el tratamiento de aguas residuales en una industria farmacéutica. Con el objeto de mejorar la mineralización de la materia orgánica, se aplicó como catalizador sulfato ferroso al sistema de reacción. Seguido de esto, se ajustó el pH del agua entre 8,5 y 10 para que el proceso se lleve a cabo en condiciones alcalinas. Finalmente, se inyectó O3 a través de un tubo Venturi con el fin de mejorar el intercambio de masa entre el gas y el agua. Los datos preliminares de operación del sistema de tratamiento señalan que este alcanza remociones de demanda química de oxígeno (DQO) menores a 10 %. Los ensayos fueron realizados a escala real y las variables de calidad del agua fueron analizadas a diferentes tiempos de reacción. Se determinó que para una dosis de ozono igual a 10 g/h y 10 mg/L de Fe2+ y un pH inicial del agua igual a 9 se requieren de 4,5 horas a fin de lograr una reducción de 30,73 % de DQO y 36,85 % de carbón orgánico total (COT). Los resultados realizados con un pH inicial superior a 9,5 señalan que la efectividad del proceso se reduce, hecho que puede ser ocasionado por la rápida formación de Fe(OH)3 insoluble, con lo cual disminuye la disponibilidad del catalizador para la formación de radicales OH* en el agua.
