Water contamination being ubiquitous problem across the world. A significant strata of population worldwide are still struggling to get drinkable water. This demand to develop technologies to provide clean water at affordable price is unveiling the need of rigorous research in this area. There are several technologies available for removal of persistent as well as emerging pollutants from water. Nanotechnology-based technology are providing the promising solution because of its extraordinary characteristics like large surface area, low cost maintenance and reuse, etc. During the past decade, there is an advancement in the field of nanotechnology and diligent efforts of researchers in achieving milestones in developing nanosorbents, nanostructured catalytic membranes, efficient photo catalysts, bioactive nanoparticles and new filtration regime. This article gives an overview of nanotechnology applications in water purification in India with an attempt to ponder indigenous technologies for implementation. A bibliometric approach is applied to bring the indigenous technologies available. In addition, we discuss some challenges associated with the development of convincing material and building water processing plants for purification of the wastewater.
水污染是世界范围内普遍存在的问题。全球仍有相当一部分人口在努力获取饮用水。这种开发技术以提供负担得起的清洁水的需求，揭示了在这一领域进行严格研究的必要性。有几种技术可用于去除水中的持久性和新兴污染物。基于纳米技术的技术因其具有大表面积、低成本维护和再利用等非凡特性，提供了有希望的解决方案。在过去的十年中，纳米技术领域取得了进展，研究人员在开发纳米吸附剂、纳米结构催化膜、高效光催化剂、生物活性纳米颗粒和新型过滤机制方面取得了里程碑式的进展。本文概述了印度纳米技术在水净化中的应用，并试图思考本土技术的实施。应用文献计量学方法来获得现有的本土技术。此外，我们还讨论了与开发令人信服的材料和建造水处理厂以净化废水相关的一些挑战。
