“…Most WWTPs utilizes various method in the conventional treatment systems for the removal of PPCPs such as coagulation, flocculation, and sedimentation of raw sewage, activated sludge, membrane bioreactor, sequential batch reactor up-flow anaerobic sludge blanket processes [ 100 , 101 ]. Some treatment methods are, however, more efficient and effective in removing pharmaceuticals compounds of interest, compared to another.…”

The presence of emerging contaminants such as pharmaceutical and personal care products in many aqueous matrices have been reported. One of such matrix is streams of wastewater, including wastewater treatment plants inflows and outflows and wastewater flow by-passing wastewater treatment plants. Their persistence arises from their resistant to breakdown, hence they may remain in the environment over long time, with a potential to cause adverse effects including endocrine disruption, gene toxicity, the imposition of sex organs, antibiotic resistance and many others in some aquatic organisms exposed to arrays of residues of pharmaceutical and personal care products. Among the treatment techniques, advanced oxidation processes have been reported to be a better technique through which these PPCPs can be degraded in the WWTPs. Heterogeneous photocatalysis using various photocatalyst immobilized on solid support such as activated carbon, graphene and carbon nanotubes in AOPs have been shown to be a viable and efficient method of PPCPs degradation. This is because, the performance of most WWTPs is limited since they were not designed to degrade toxic and recalcitrant PPCPs. This review highlight the occurrence, concentration of PPCPs in wastewater and the removal efficiency of heterogeneous photocatalysis of TiO2 immobilized on solid supports.

Nowadays, the water contamination which is due to pharmaceuticals is increasing and alarming. The pharmaceuticals in water are very hazardous and toxic not only for the human life but also for environment. One of the promising methods of removing pharmaceuticals from the contaminated water is adsorption. Agricultural and industrial wastes or by-products can be used as low-cost adsorbents for pharmaceuticals removal. Low-cost adsorbents provide particular economic and environmental advantages. This paper presents an overview of utilizing of the waste-based adsorbents (mainly spent coffee grounds) for the removal of pharmaceuticals from water.

“…Los productos farmacéuticos y de cuidado personal representan lo que se ha denominado actualmente como contaminantes emergentes. Este tipo de sustancias no son monitoreadas de forma rutinaria en las plantas de tratamiento de aguas residuales, además, debido a sus características pueden ocasionar efectos adversos en el ambiente a largo plazo [1]. Como parte de los productos farmacéuticos de uso común en humanos y animales, se pueden mencionar los antibióticos, este tipo de sustancias son de particular interés por su potencialidad para promover resistencia en los microrganismos existentes en los cuerpos de aguas, que son los receptores de aguas residuales [2], [3].…”

Esta investigación se llevó a cabo para evaluar la reducción de la concentración de cefalexina (CEF), en solución acuosa por medio de electrocoagulación (EC) con electrodos de grafito como alternativa de eliminación de este contaminante en las aguas residuales. En primer lugar, se ajustó la conductividad eléctrica del agua con NaCl, lo que permitió la formación de especies de cloro activo (HOCl y OCl-). Se emplearon electrodos de grafito debido a sus características frente al desgaste del ánodo, que ocurre con los sistemas en los cuales se emplean ánodos metálicos. Se analizó el efecto del pH inicial de la solución (7 y 8) y la intensidad de corriente aplicada (1 A y 1,5 A). Para evaluar el efecto de estas variables, se implementó un diseño experimental de tipo central compuesto y la metodología de superficie de respuesta. Adicionalmente, se determinó las condiciones de las variables de estudio las cuales permiten alcanzar la mayor efectividad del proceso. Se determinó que a un nivel de pH 7 y una intensidad de 1,5 A se alcanza una remoción del 75,5 % en la concentración de cefalexina. Para un pH 8 se observa una considerable disminución del porcentaje de reducción de concentración de cefalexina, esta situación implica que la variable que presenta mayor influencia sobre la variable de respuesta es el pH de la solución acuosa.
