Abstract

In the present era of scarcity of water resources, effective treatment of wastewater is a major prerequisite for growing economy. It is critical to develop and implement advanced wastewater treatment technologies with high efficiency and low capital requirement. Among various treatments, recent advanced processes in nano-material sciences have been attracting the attention of scientists. However, limited collective knowledge is available in this context. The present manuscript reviews the potential developments in nanotechnology with respect to wastewater treatment. The article reviewed and discussed utilization of various classes of nano-materials for wastewater treatment processes. This includes four main classes; First, nano-adsorbents such as activated carbon, carbon nanotubes, grapheme, manganese oxide, zinc oxide, titanium oxide, magnesium oxide and ferric oxides that are usually applied for removal of heavy metals from the wastewater. Second, nano-catalysts such as photocatalyst, electrocatalyst, Fenton based catalyst, and chemical oxidant have been shown the potential for removing both organic and inorganic contaminants. Third, nano-membranes have been used for effective removal of dyes, heavy metals and foulants using carbon nanotube membranes, electrospun nanofibers and hybrid nano-membranes. Finally, the integration of nanotechnology with biological processes such as algal membrane bioreactor, anaerobic digestion and microbial fuel cell is discussed with respect to its potential for wastewater purification.

  • Many efficient, environmentally friendly, and economical nanomaterials can be used to treat water and wastewater.

    “Many efficient, environmentally friendly, and economical nanomaterials can be used to treat water and wastewater.”

    From Emerging nanotechnology approaches for sustainable water treatment and heavy metals removal: a comprehensive review (2025) · cites this paper as [52]

    The Introduction and Conclusions describe various nanomaterials used effectively in wastewater treatment, and §4 calls nano-membrane filtration economical. But the Conclusions caution that nanoparticles may pose environmental risks and that most nanomaterials are not yet cost-competitive; the paper does not establish all three qualities for the many materials claimed. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Nanomaterials have distinct physical, chemical, and biological properties, giving them unique capabilities for decontaminating industrial effluents, drinking water, surface water, and ground water.

    “These nanomaterials have distinct physical, chemical, and biological properties, giving them unique capabilities for decontaminating industrial effluents, drinking water, surface water, and ground water.”

    From Emerging nanotechnology approaches for sustainable water treatment and heavy metals removal: a comprehensive review (2025) · cites this paper as [52]

    The Introduction states that nanomaterials have unique functionalities for potential decontamination of all four named water sources. Section 2, “Nano-adsorbents,” discusses physical and chemical properties, but our copy does not establish distinct biological properties of nanomaterials as a basis for those capabilities. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Nano-filtration is widely used in industries for wastewater treatment due to its small pore sizes, cost-effectiveness, excellent effectiveness, and ease of use.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
