Summary: The petroleum industry is rapidly growing, leading to increased environmental concerns about wastewater treatment. Advanced oxidation processes (AOP) have been applied for treating petroleum wastewater due to the limitations of conventional treatment methods. Different AOP techniques have shown varying degrees of efficiency in treating petroleum wastewater based on the contaminants present and operating conditions. Ongoing research focuses on further improving the AOP treatment methods for petroleum wastewater.

Summary: The discharge of pollutant-rich wastewater without adequate treatment poses a serious threat to the environment. Catalytic and photocatalytic ozonation using metal ferrite are promising methods for making the treated wastewater reusable. This review summarizes the recent advances in metal ferrite nanoparticle catalysts, exploring their preparation methods, characterization techniques, catalytic mechanisms, and modification strategies. Furthermore, the current applications of metal ferrites as ozone catalysts and the synergistic effect of catalytic and photocatalytic ozonation are discussed. The pollutant removal efficiencies using metal ferrite are 20-40% for non-catalytic ozonation, 80-98% for catalytic ozonation, and 60-80% for photocatalytic ozonation.

Summary: Research on anodic oxidation of synthetic wastewater based on Algiers refinery effluent found that variation in stirring degree had significant effects on COD removal and energy consumption. Current density was found to have different effects on removal efficiency within the applied stirring domain. The mass transport coefficient was inversely correlated with energy consumption, highlighting its importance in improving efficiency.

Summary: We investigated the catalytic activity of magnetic CeZrUiO-66 Metal-Organic Framework (MOF) composites (Fe3O4/CeZrUiO-66) for ciprofloxacin degradation by catalytic ozonation. The composite with a 30:70 ratio of Fe3O4:CeZrUiO-66 exhibited the highest efficiency, achieving a 97% elimination yield within 30 minutes. The catalytic ozonation process (COP) showed higher CIP mineralization compared to the single ozonation process (SOP), and OH radicals were identified as the main reactive species.

Summary: The study characterized two significantly different DOM samples from petroleum refinery wastewater and river water using FT-ICR MS with various ionization modes. It was found that wastewater DOM was dominated by acid O-x and basic N1Ox classes in negative-ion and positive-ion ESI mode, respectively. Refinery wastewater DOM showed higher molecular complexity and enrichment in hydrocarbons, nitrogen- and sulfur-containing compounds compared to riverine DOM.

Summary: This study evaluated a new combined treatment approach by combining ozonation and electrolysis for the mineralization of organic compounds in water. The results showed that the method was most effective for TOC removal in alkaline conditions and significantly enhanced performance compared to ozonation alone in acidic conditions. The initial pH had a more significant effect on TOC removal than current density, but both parameters were relevant. Under optimized conditions, 63% TOC removal was achieved.

Summary: Refinery wastewater, which is both voluminous and complex in composition, necessitates multi-stage treatment to meet discharge or reuse targets. Traditional pretreatment technologies using inclined plate settlement combined with two-stage air flotation for petroleum and suspension removal suffer from high energy and chemical consumption, as well as generation of significant amounts of hazardous waste. This study introduces a short-process physical pretreatment technology that employs combined fiber coalescer (CFC) and granular media filter (GMF). Pilot testing demonstrates that the treated refinery wastewater, without the addition of chemicals, becomes clear and translucent, with petroleum and suspended solids content reduced to below 20 mg/L, falling within the acceptable range of biochemical influent index. This process greatly reduces the generation and emission of scum and volatile organic compounds (VOCs), providing a new technique for low-carbon pretreatment of refinery wastewater.

Summary: The presence of salts, particularly chloride ions, significantly influences the performance of both conventional and catalytic ozonation processes by affecting the rate and extent of organic compound degradation. This influence is due to scavenging of O-3, transformation of organics to more hydrophobic forms, and inhibition of hydroxyl radicals. Through appropriate choice of catalyst, this effect can be mitigated to some extent.

Summary: Petroleum refineries often use the hydrodesulfurization (HDS) process to purify petroleum products and reduce SO2 emissions. However, HDS is still challenging due to various factors influencing sulfur removal rates. Machine learning algorithms can be used to predict the yields of the HDS process and help optimize it.

Summary: Propranolol hydrochloride is a persistent and bioaccumulative pharmaceutical in the environment, with potential toxicity and adverse effects. The efficiency of TiO2-La 0.05%-CMCD nanoparticles in degrading propranolol under UV-light irradiation is higher than that of pristine TiO2, possibly due to complex formation between the beta-blocker and the oligosaccharide.

Summary: This work is a critical review of various aspects of the peach palm plant, including its historical, botanical, social, environmental, and nutritional aspects. The cultivation of B. gasipaes has become increasingly important in Brazil, especially for the production of palm heart. Recent efforts have also focused on the potential valorization of the fruit as a source of carotenoids and starch. The lignocellulosic wastes of B. gasipaes have great potential for being upcycled into valuable biotechnological products.

Summary: The use of nanofluids in enhanced oil recovery processes has gained attention due to the possibility to increase oil recovery from mature oil fields. Silica nanoparticles are widely used for nanofluid formulations, but there are obstacles such as stability, environmental and economic aspects, and the need for suitable large-scale production processes. This study evaluates oil recovery using silica-based nanofluids from different sources under various operational conditions, and demonstrates that silica from rice husk ash has comparable efficiency to other synthetic silica nanoparticles.

Summary: The use of ceramic membranes for microfiltration has increased due to their high performance and physical-chemical properties. However, their production is expensive. Geopolymeric membranes (GPMs) have been developed as a cheaper alternative by incorporating industrial waste. In this study, GPMs were synthesized by incorporating magnetic mining waste (MMW) and were used successfully to remove trimethoprim antibiotic from an aqueous solution.

The pretreatment significantly increased the yields of total reducing sugars and glucose from the inner sheaths, but had no effect on the peel. Scanning electron microscopy revealed structural modifications in the inner sheaths after pretreatment, but no changes were observed in the peel.
