Abstract In treating slaughterhouse wastewater (SWW), conventional treatment processes (CTPs) such as anaerobic processes, membrane and electrocoagulation have various weaknesses, including limited effectiveness, fouling issues, high energy consumption. Conversely, photocatalytic advanced oxidation (PAOPs) demonstrated superiority over CTPs. However, the effectiveness of PAOPs significantly diminishes when SWW contains levels suspended solids (SS). This research explores feasibility pre‐treating synthetic (SSWW) using a novel yeast‐assisted dissolved air flotation (YADAF) process to reduce SS level. utilizes H 2 O catalase enzymes from inexpensive yeast, readily available in local markets. Under optimized conditions, this combination generates bubbles uplift particles flocs, which can then be removed via mechanical scraper before undergoing with UV/H /TiO PAOP under conditions. The enhanced yielded 93.75%, 83.23%, 94.35% reduction chemical oxygen demand (COD), 5‐day carbonaceous biochemical (CBOD 5 ), total (TSS), signifying increments 41.15%, 56.59%, 2867% COD, CBOD , TSS, respectively, compared alone, unenhanced. demonstrates that YADAF amplifies PAOP, making it viable pre‐treatment option complements latter SSWW. Practitioner Points Yeast‐assisted floatation is variant (DAF) capable removing TSS 15 min. On top that, combined (AOP), deliver used treat (SSWW). has never been field prove valuable addition ready implemented into current technologies.

The term &lsquo;photocatalysis&rsquo; has recently gained high popularity, and various products using photocatalytic functions have been commercialized. Of all the materials that may be used as photocatalysts, TiO2 is virtually only one now most likely will remain appropriate for industrial application. Water air purification systems, sterilization, hydrogen evolution, self-cleaning surfaces, photoelectrochemical conversion are just a few of applications in environmental energy domains make extensive use photocatalysis. This due to fact lowest cost, stability, effective photoactivity. Furthermore, history attests its safety both people environment because it white pigment since antiquity. review discusses some important aspects issues concerning different synthesis methods their influence on structure properties TiO2, well concept photocatalysis based promising biocompatible functional material widely recent years. advantages fields science technology discussed, including protection, water liberation, photovoltaic energy, cancer diagnosis therapy, coatings dental products, etc. Information phases, modern them presented. followed by detailed basic principles with brief introduction Finally, challenges prospects briefly discussed. Recent advances fundamental understanding at atomic-molecular level highlighted, summarized terms design engineering new materials.

A new catalyst, Sm2NdSbO7, was synthesized for the first time by solid-phase sintering. The study utilized X-ray diffraction, transmission electron microscope energy dispersive spectroscopy, and photoelectron spectroscopy to examine structural characteristics of monocrystal BiDyO3, Sm2NdSbO7 Sm2NdSbO7/BiDyO3 heterojunction photocatalysts (SBHP) prepared photocatalyst owned a pyrochlorite structure, belonged face-centered cubic crystal system, possessed space group Fd3m bandgap width 2.750 eV. After 145 min visible light irradiation (145-VLIRD), removal rate (RMR) methyl parathion (MP) or total organic carbon SBHP 100% 97.58%, respectively. 145-VLIRD, photocatalytic degradation rates MP were 1.13 times, 1.20 2.43 times higher than those photocatalyst, BiDyO3 nitrogen-doped TiO2 experimental results showed that had good activity. four cycles cyclic experiments with SBHP, elimination 98.76%, 97.44%, 96.32%, 95.72%, stability. Finally, possible pathways mechanisms speculated. In this study, we successfully developed high-efficiency catalyst which responded significant could be used in reaction system eliminating harmful pollutants from wastewater.
