Rising water scarcity, together with increased industrial wastewater production, suggests reusing of wastewater for plant irrigation. The wastewater from Razi petrochemical complex contained different salts and heavy metals. Variation in responses to wastewater irrigation has recommended appropriate levels of mineral nutrients in diluted wastewater that stimulated plant growth, and toxic levels of salts in undiluted wastewater that restricted plant growth. The undiluted wastewater irrigation significantly decreased chlorophyll fluorescence, along with photosynthetic capacity, while wastewater dilution mitigated its adverse effect. High levels of salts in undiluted wastewater induced an imbalance in plant mineral nutrients, which was evidenced with increased lipid peroxidation and reduced plant growth. On the contrary to adverse effects of undiluted wastewater on plant performance, the diluted wastewater, especially at 50% level, behaved as a fertilizer which increased leaf mineral nutrients, photosynthetic capacity, morphological and anatomical features of plant, but decreased lipid peroxidation. In relation to improvement in photosynthetic capacity, a significant increase was achieved in stomatal traits in plants irrigated with half-strength wastewater. In conclusion, due to the nutrition values of wastewater, it can be suggested to irrigate plants with diluted wastewater with the aim of improving crop productivity and saving freshwater sources.

Key nutrients, such as nitrogen measured as total ammonium nitrogen (TAN), could be recycled from hydrolysed human urine back to fertiliser use. Bioelectrochemical systems (BESs) are an interesting, low-energy option for realising this. However, the high TAN concentration (> 5 g L) and pH (> 9) of hydrolysed urine can inhibit microbial growth and hinder the enrichment of an electroactive biofilm at the anode.

Anaerobic digestion (AD) offers a reliable strategy for resource recovery from source-separated human feces (HF), but is limited by a disproportionate carbon/nitrogen (C/N) ratio. Ferrous hydroxyl complex (FHC) was first introduced into the HF-AD system to mediate methanogenesis. Mono-digestion of undiluted HF was inhibited by high levels of volatile fatty acids (VFAs), ammonia, and hydrogen sulfide (HS).

Industrial wastewater effluents are a major source of chemicals in aquatic environments, and many of these chemicals may negatively impact aquatic life. In this study, the crustacean Daphnia magna, a common model organism in ecotoxicity studies, was exposed for 48 h to nine different industrial effluent samples from manufacturing facilities associated with the production of plastics, polymers, and coating products at a range of dilutions: 10, 25, 50, 100% (undiluted). A targeted metabolomic-based approach using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to quantify polar metabolites from individual daphnids that survived the 48 h exposure.

Three penicillin-based β-lactam antibiotics (benzylpenicillin, amoxicillin, and ampicillin) were extracted by electromembrane extraction (EME) and determined in the resulting extracts by capillary zone electrophoresis (CZE) with UV-Vis detection. The EME was optimized for the simultaneous clean-up of complex samples and preconcentration of the three antibiotics and employed 1-octanol as the organic phase interface (impregnated in the pores of a hollow fiber), acidified donor solution (pH 3), and phosphate buffer (pH 5.6) as the acceptor solution.

Wastewater treatment targeting reuse may limit water scarcity. Photocatalysis is an advanced oxidation process that may be employed in the removal of traces of organic pollutants, where the material choice is important. Titanium dioxide (TiO) is a highly efficient photocatalyst with good aqueous stability.
