The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa ) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.

“…En estos procesos se pueden obtener resultados mejorados de la generación de radicales •OH por medio de la adición de UV (47-48), Peróxido de hidrogeno (H 2 O 2 ) (21-48), catalizadores (8-49), entre otros. El acoplamiento entre los procesos basados en ozono y los biológicos ha sido estudiado en su mayoría empleando un proceso basado en ozono como postratamiento, aprovechando las instalaciones comunes de tratamientos biológicos para lixiviados en los rellenos sanitarios (41)(42)(43)(44)(45)(46)(47)(48)(49)(50).…”

El tratamiento de lixiviados de rellenos sanitarios requiere de procesos que permitan la remoción eficaz de los diferentes contaminantes presentes en este tipo de residuos líquidos. Para el tratamiento de este tipo de residuos se han empleado una gran diversidad de procesos biológicos, los cuales aprovechan la capacidad de transformar los diferentes componentes del medio liquido en biomasa, sin embargo, estos procesos poseen limitaciones debido a las características intrínsecas del lixiviado. En los últimos años se ha impulsado la integración de los procesos biológicos con los Procesos Avanzados de Oxidación, lo cual permitiría reducir significativamente las características toxicas de estos residuos para así cumplir con las condiciones legales para ser vertidos al ambiente sin que se produzcan daños. En la presente revisión se investigan los trabajos recientes (2015 a 2021) referentes al tratamiento biológico y con procesos Avanzados de Oxidación (basados en ozono, procesos electroquímicos y fotocatálisis). Estos procesos se analizan en combinación, para describir las condiciones óptimas en las que se reducen las cargas contaminantes de los lixiviados de rellenos sanitarios. Finalmente es posible identificar que los procesos de tratamiento en estudio son tecnologías que pueden ser acopladas, registrando mayor eficacia y menor generación de subproductos de desecho o lodos.

“…Some conventional treatments applied to these wastes include biological processes, such as aerobic–anaerobic ones, and membrane technology. On the other hand, it is possible to apply chemical treatments such as coagulation-flocculation or mixtures of physical-chemical treatments for higher efficiency [ 8 , 9 , 10 , 11 ].…”

In the present study, nine fabrics have been tested for brackish water treatment with the aim of industrial application under the concept of zero liquid discharge (ZLD). Moisture content was determined, where it was observed that the lignocellulosic fabrics had a moisture content ranging from 2.5 to 8.5%. The wetting contact angle showed that the flax with polylactic acid (LPLA) was the most hydrophobic. The determination of the liquid absorption capacity showed that, of the synthetic fabrics, the one with the highest absorption, both in distilled water and in brackish water, was the polyester (PES) fabric with an absorption of 816% compared to its initial weight. In the natural fabrics, the highest absorption capacity was shown by the wet-laid without treatment (WL-WT) fabric for both distilled water and brackish water, although it required several cycles of operation to maintain this stable absorption. Exposure to brackish water improved the absorption capacity of all samples. Mechanical and thermal characterization showed that the synthetic fabrics were more resistant than the natural fabrics, although they may compete in terms of applicability. The capillarity study showed that the most hydrophilic fabrics completed the test the fastest. Finally, the composting degradation test showed that those fabrics with polylactic acid (PLA) content degraded faster in the first 14 days and thereafter the degradation of the lignocellulosic content showed a slower degradation until 112 days. The Bam fabric did not degrade during the course of the experiment.
