Published: Feb. 25, 2025

Remediated water reuse is becoming vital for sustainable management, reducing the strain on freshwater resources, particularly in agriculture and industrial activities. Behind application irrigating crops processes, treated should be employed indirect direct potable use. In latter case, traditional approaches to wastewater treatment have been found inefficient, especially concerning biological contamination, persistent organic pollutants (POPs) and/or contaminants of emerging concern (CECs). Given that, according its origin foreseen use, each needs a specific treatment. A plethora new or improved materials, combinations different treatments check analyses are continuously developed tested at laboratory scale, first, necessary but not sufficient, step towards solution. Various innovative were pilot reduced number procedures applied full resulting significant production remediated desired quality. The present review focuses most recent outcomes obtained from remediation both scales discusses gaps which still hinder exploitation solutions advancements real-scale application.

Biodegradable Polymers for Plant Nutrient Delivery and Recovery

Macromolecular Bioscience, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

The current use of fertilizers is inefficient and not sustainable. majority the fertilizer applied does reach targeted crop but lost in water bodies into atmosphere, with harmful impact on environment. To enhance efficiency sustainability agricultural practices, it essential to address two complementary challenges. First, nutrient delivery methods must be refined maximize plant uptake. Second, recovery nutrients from wastewater other waste streams should improved recycling nitrogen phosphorous reduce environmental pollution. Biodegradable polymers hold great promise for development technological solutions toward more sustainable practices. This review covers application biodegradable both aspects cycle: plants through slow- controlled-release fertilizers, using membrane separation, adsorbent composites, coagulants/flocculants. most promising materials are highlighted approaches, identifying research gaps discussing potential future directions this highly significant field.

Integration of coagulation–flocculation and photolysis processes for treating reverse osmosis concentrate (ROC) of pharmaceutical wastewater management

International Journal of Environmental & Analytical Chemistry, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 27

Published: June 13, 2024

This study provides novel insights into optimizing the integral treatment process, contributing to ROC strategies. A comprehensive approach for reverse osmosis concentrate (ROC) from pharmaceutical wastewater was investigated using an system consisting of a coagulation-flocculation and photolysis process. Ferric chloride (FC) poly-aluminum (PAC) are examined as coagulants within range (0.1–1) gL−1, focusing on turbidity, chemical oxygen demand (COD), total organic carbon (TOC) removal. The findings show that optimal FeCl3 dosage is 0.4 achieving significant turbidity reduction 1 NTU. PAC at 0.2 gL−1 optimal, reducing NTU exhibiting non-linear behavior in COD TOC removal, introducing them starting point post-treatment. Photolysis treated samples pH 7 yields reductions 60.5% 79.5% FC, with respective 75.23% over 360 min. At (pH 3.5) showed ROC.
