ANN models for predicting wastewater treatment efficacy of biomaterial adsorbents.

Endocrine disrupting chemicals are a group of contaminants that have severe effects on humans and animals when exposed, like cancer and alterations to the nervous and reproductive systems.

Mining wastewater treatment (MWWT) methods have played a vital role in sustainable water management in recent years.

Preparation of bentonite clay–coconut husk composite (BECH) via microwave-assisted carbonization, the activation of BECH with HCl (BECH-H) and KOH (BECH-K) and the adsorption of ciprofloxacin, tetracycline, and bisphenol A from aqueous solutions.

The RAVEN STREAM online tool aims to help sewage treatment plants (STPs) identify and manage industrial chemicals used upstream that, if spilled, could cause a toxic shock to the STP microorganisms utilized in the wastewater treatment process.

Nitrogen-doped g-C₃N₄/CoS nanocomposites have been synthesized using a facile polycondensation-hydrothermal method and showed improved photocatalytic activity for the degradation of MB dye and industrial real samples with good photostability.

Planetary ball milling assisted piezocatalysis for water cleaning application.

Photocatalytic H₂O₂ generation under visible light irradiation over magnetic resorcinol–formaldehyde is coupled with UVC activation for on-site water purification.

A porous GO@Zn–Hap@CA adsorbent of high roughness offers ultra-high and rapid adsorption of Cr(VI) and Pb(II) ions from aqueous environments.

The present work unveils the reusable photocatalytic action of strontium oxide (SrO) nanoparticles synthesized using Albizia julibrissin plant extract via the co-precipitation method.

A MIL88-A/PS/solar system is a highly efficient and cost effective AOP for a full and rapid degradation of SMX antibiotic in a water matrix.

A virtuous biowaste cycle replicated in three industrial sites (Italy, Greece and Cyprus) yielding value added products (SBO) for agriculture and chemicals' bioeconomy. A cofunded LIFE project.

This study involves the fabrication of a novel, sustainable, and economically viable adsorbent ceria/rice flour/montmorillonite nanocomposite (Ce-R-MMT) for the decontamination of Cr(VI) and Coomassie brilliant blue (CBB) from the aquatic phase.

This study developed a molecular identification method for fluoride in industrial wastewater and explored the adsorptive removal of fluoroborate by strongly basic ion exchange resin.

A TiO₂/Ti₃C₂ MXene aerogel composite was synthesised for photocatalytic degradation of palm oil mill effluent.

Lead and zinc mines are a primary source of environmental (post)-transition metal contamination resulting in major water pollution. Wood ash amended biochar has the potential to remediate mine contaminated water.

This study optimized the removal of phosphate in a wastewater treatment plant using a phosphate automated analyzer in the final discharge effluent.

Ibuprofen, a widely used non-steroidal anti-inflammatory, anti-pyritic and analgesic, occurs in the aquatic systems of 47 countries. It was removed (∼70 mg g⁻¹ Langmuir and ∼30 mg g⁻¹ at 7.5 mg L⁻¹ by column uptake) at <40% of activated carbon’s cost.

GO, CuO-rGO and ZnO-rGO were tested for their ability to remove textile dyes (R-6G, MG) and antibiotics (AMOX, TC) as wastewater depollution materials. Although GO was most effective for the cationic dyes, CuO-rGO efficiently removed anionic antibiotics.

PAD reduces nitrogen and solids following anaerobic digestion without external carbon supplements.

Magnetic Zr-MOFs show excellent performance towards heavy metal capture from contaminated water.

With the objective of establishing an overview of the limits of hydroxylamine-induced acceleration of the Fenton process, the impact of processing conditions and water matrix composition on the degradation of persistent dyes is revealed in this work.
