Abstract

This study assesses the efficacy of natural clays as a cost-effective and ecologically sound method for the removal of tetracycline from water. A notable advancement in the field of antibiotic removal is the utilization of honeycomb monoliths in lieu of traditional powder-based materials. The objective of this approach is to facilitate easier handling and to mitigate the production of sludge. The findings illustrate that, among the five clay types studied, the kerolitic montmorillonite is particularly effective in removing tetracycline from water, achieving levels of approximately 100 mg/g. This effectiveness is remarkably consistent across a range of pH levels (both acidic and basic), temperatures (4–60 °C), and even flow rates when employing the honeycomb design (50–2800 mL/min). These results substantiate the efficacy of this approach as a robust and promising strategy for wastewater treatment. In light of the fact that the principal mechanism of action for these clays is adsorption, the study also addresses ancillary concerns such as filter cleaning for reuse and the complete elimination of tetracycline.

利用粘土蜂窝状单体去除水中的四环素抗生素

本研究评估了天然粘土作为一种具有成本效益且无害生态的方法去除水中四环素的功效。抗生素去除领域的一个显著进步是利用蜂窝状单体取代了传统的粉末状材料。这种方法的目的是便于处理和减少污泥的产生。研究结果表明，在所研究的五种粘土类型中，角闪石蒙脱石对去除水中的四环素特别有效，可达到约 100 毫克/克的水平。在不同的 pH 值（酸性和碱性）、温度（4-60 °C），甚至采用蜂窝设计时的流速（50-2800 mL/min）下，这种效果都非常一致。这些结果证明了这种方法的有效性，是一种稳健而有前途的废水处理策略。鉴于这些粘土的主要作用机理是吸附，该研究还解决了一些辅助问题，如过滤器的清洁再利用和完全消除四环素。

期刊介绍： The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
