With the advancement of structurally complex systems, smart and flexible membranes have gained significant attention for treating contaminated wastewater. This study develops a flexible and intelligent piezocatalytic composite membrane reinforced with 2D carbon nanoparticles derived from the pyrolysis and activation of ground tire rubber (GTR). The membranes, based on polyvinylidene fluoride (PVDF), were fabricated using non-solvent induced phase separation (NIPS) by incorporating styrene-ethylene-butylene-styrene (SEBS) at 7.5 wt.% and 2D carbon nanoparticles at varying concentrations (0.5 to 5 wt.%). The size distribution of the carbon nanoparticles and the morphological properties of the membranes were characterized using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The mechanical, electrical, and thermal properties of the membranes were evaluated through tensile tests, electrical conductivity measurements, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), and contact angle (CA) analysis. The incorporation of 2D carbon nanoparticles facilitated the transformation of PVDF into the piezoelectric β-phase, with the 3 wt.% carbon-doped membrane exhibiting exceptional mechanical and thermal properties. This membrane also demonstrated a significant increase in electrical conductivity, from 10⁻¹¹ S cm⁻¹ to 10⁻⁵ S cm⁻¹. Furthermore, the membrane achieved remarkable degradation efficiencies of 79.07% for methylene blue (MB) and 94.56% for toxic rhodamine B (RhB). This work highlights the successful production of 2D carbon nanoparticles from tire waste and their application in creating polymorphic piezocatalytic membranes with high piezoelectric performance and pollutant degradation capabilities.

Next, a two-level clustering approach is applied, where self-organizing maps (SOM) perform coarse clustering to reduce noise, and K-means refines cluster boundaries for more precise operating condition classification. Finally, a Correntropy-based robust reconciliation estimator mitigates measurement noise and outliers, enhancing accuracy across diverse operating states.

The degradation mechanism was explored using sulfamethoxazole as a model compound through scavenger experiments, byproduct analysis, and also toxicity assessment. Hydroxyl and sulfate radicals were identified as the primary agents responsible for PPCPs removal, along with hydrated electrons, hydrogen radicals, superoxide radicals, and singlet oxygen. Singlet oxygen was identified as a reactive species for the first time. The degradation pathways of sulfamethoxazole were examined, identifying five byproducts, and assessing the toxicity of these byproducts, finding minimal Microtox® toxicity. The influence of water matrix constituents and the effect of a real water matrix on mixed PPCPs removal were also explored. The results indicate that water matrix constituents compete for light absorption and quench hydroxyl radicals, leading to decreased degradation efficiency.

This study aims to assess the long-term performance, maximize treatment capacity limits across different phases, microbial community dynamics, and granule characteristics of an up-flow anaerobic sludge blanket (UASB) reactor in response to increasing loadings of water hyacinth juice (WHJ). The findings demonstrated that the reactor maintains stable effluent pH levels (7.2–8.9) and supports high biogas production rates throughout the process.

Thus, balancing these elements is crucial for improving the water-energy‑carbon nexus of the system. Economically, water prices can influence total water consumption. Taking this concept further, adjusting the hourly water price can help shift user demand to more favorable hours. Based on price elasticity, the water price was optimized to fluctuate at specific times throughout the day, potentially changing the user water consumption pattern. We developed a methodology to simulate the effects of these price adjustments by considering factors such as population, demand uncertainty, income class, price elasticity, and water conservation awareness.
