Water supply around the globe is struggling to meet the rapidly increasing demand by the population, drastic changes in climate and degrading water quality. Even though, many large-scale methods are employed for wastewater treatment they display several negative impacts owing to the presence of pollutants. Technological innovation is required for integrated water management with different groups of nanomaterials for the removal of toxic metal ions, microbial disease, organic and inorganic solutes. The method of manipulating atoms on a nanoscale is nanotechnology. Nanomembranes are used in nanotechnology to soften water and eliminate physical, chemical and biological pollutants. The present review concentrates on various nanotechnological approaches in wastewater remedy, mechanisms involved to promote implementation, benefits and limitations in comparison with current processes, properties, barriers and commercialization research needs. Also the review identifies opportunities for further exploiting the exclusive features for green water management by following the advances in nanotechnology.
全球的水资源供应正努力满足人口的快速增长、气候变化的剧烈变化和水质恶化的需求。尽管已经采用了许多大规模的方法来处理废水,但由于污染物的存在,它们显示出了一些负面影响。为了进行综合水资源管理,需要采用不同的纳米材料组来去除有毒金属离子、微生物疾病、有机和无机溶质。对原子进行纳米级操纵的方法是纳米技术。纳米膜在纳米技术中被用于软化水和去除物理、化学和生物污染物。本综述集中讨论了废水处理中各种纳米技术方法,涉及的机制以促进实施,与现有工艺相比的好处和限制,以及性质、障碍和商业化研究需求。该综述还确定了通过跟踪纳米技术的进步,进一步利用绿色水资源管理的独特功能的机会。
