Summary: This study evaluated the use of sodium sulfite as an electron acceptor for a modified anaerobic baffled reactor to treat the wastewater produced from ASP flooding, successfully removing COD, oil, suspended solids, polymers, and surfactants. Monitoring the changes in organic compounds and characterizing microbial communities revealed the effectiveness of this method in degrading organic pollutants and promoting the dominance of Halomonas sp. in degrading hydrocarbons under high pH and salt stress. These findings contribute to the development of a cost-effective biological system for treating wastewater from ASP flooding.

Summary: In this study, a novel PQA-PDA@Fe3O4 nanoparticle demulsifier was developed to efficiently demulsify asphaltene-rich ASP flooding emulsions. The nanoparticles demonstrated excellent demulsification efficiency by coalescing fine oil droplets into large aggregates and inhibiting secondary emulsification. The magnetic properties of the nanoparticles also accelerated the aggregation process and allowed for magnetic recyclability.

Summary: More than half of the world's oil and gas resources are found in carbonate reservoirs, but conventional oil recovery processes leave 60% of their residual oil behind. The complexity of carbonate reservoirs, including weak water imbibition, undesired capillary forces, low permeability, and oil wetness, leads to precipitation of injection chemicals and the entrapment of residual oil. Therefore, purposefully designed chemicals known as alkaline-surfactant-polymer (ASP) are expected to enhance oil recovery in these challenging reservoirs. This research focuses on improving the oil production mechanisms in carbonate porous medium using a synthesized ASP combination. The results show promising oil recovery percentages under harsh reservoir conditions.

Summary: Through analyzing the properties of ASP produced water in Daqing Oilfield, it was found that the critical micelle concentration of ASP produced water is greatly affected by pH and slightly affected by temperature. The addition of polymer increases the viscosity of produced water and enhances its stability. The presence of inorganic salts promotes the formation of surfactant micelles in ASP produced water, further enhancing its stability.

Summary: The effects of secondary emulsification of field ASP flooding produced fluid by centrifugal pumps and electrostatic field on oil/water separation performances were evaluated. It was found that secondary emulsification drastically downgraded the separation performances, especially in fluids with high surfactant content. The ASP flooding produced fluid had lower oil/water interfacial tension, making it more susceptible to shear and high strength electrostatic field.

Summary: The study revealed that suspended microcrystalline polymer flooding produced water has unique characteristics in terms of oil droplet diameter distribution, viscosity, and absolute zeta potential. The oil removal rate through gravity sedimentation was found to be higher compared to polymer-flooding produced water and slightly lower than high Ca and Mg polymer flooding produced water. A two-stage composite material filtration combined with gravity sedimentation was proposed as an effective and practical method for oil removal from suspended microcrystalline polymer flooding produced water based on laboratory experiments.

Fireworks and explosives production industries were determined to be the major sources of perchlorate contamination in surface water. Risk assessment and policy intervention should focus on the central-southern part of China and the central part of Xinjiang province to prevent perchlorate contamination.

Summary: The type and dose of disinfectants affect the formation of MnOx deposits in pipes. Chlorination leads to MnOx accumulation, while chloramination has almost no accumulation. Low dose of free chlorine also reduces Mn deposit formation. Biotic Mn(II) oxidation occurs when disinfection is discontinued, and it is inhibited again when disinfection is resumed.

Summary: It was found that dissolved organic matter (DOM) in natural water has ubiquitous competitiveness against organic micropollutants (OMPs) during adsorption onto activated carbon. However, not all adsorbable DOM fractions are competitive. The poorly adsorbable DOM was shown to be a non-competitive co-adsorbate and can even enhance the adsorption capacity of certain OMPs. The amount of DOM competitors increased for weaker adsorbable OMPs and at higher initial OMP concentrations.

Summary: This study investigated the treatment of Ethinyl Estradiol (EE2) in swine wastewater using an Upstream Solids Reactor (USR), and proposed a new method for bio-feeding regulation to enhance the anaerobic biodegradation process. The addition of propionic acid was found to be more effective in enhancing the removal of EE2 compared to lactic acid. However, controlling the pH at extreme values hindered the fermentation process and negatively affected EE2 removal. The study provides insights into the anaerobic biodegradation of EE2 and suggests a new strategy for the bioremediation of refractory pollutants.

Summary: Cyanobacteria can adjust their photosynthetic pigments to sense different light colors. Some filamentous cyanobacteria increase their phycoerythrin (PE) levels in green light, leading to extensive odor problems in drinking water reservoirs. This study found a correlation between MIB biosynthesis and chromatic acclimation (CA) induced by ambient light color in a MIB-producing Pseudanabaena strain. Pseudanabaena regulates pigment proportion through CA3, increasing PE and decreasing phycocyanin (PC) in green light. MIB production and chlorophyll a (Chl a) biosynthesis are positively correlated regardless of light color.

Summary: This study investigated the role of activated carbon properties in the adsorption of effluent organic matter (EfOM) from bio-treated coking wastewater. Commercial powdered activated carbons (PACs) with different pore structures, surface functional groups, and surface charges were used. The results showed that the adsorption of EfOM depended on its molecular size, with biopolymers being adsorbed by macropores and humics being adsorbed by mesopores. PACs with higher mesopore volume, fewer acidic groups, and higher isoelectric point were found to be more effective in removing EfOM.

Summary: Cellular 2-methylisoborneol (MIB) yield in cyanobacteria varies under different conditions, making MIB prediction ineffective. Through a field survey, we found that mic gene abundance and expression could serve as indicators for early warning of MIB production. Light intensity was identified as the key regulator for mic gene expression and MIB synthesis. We developed a model using mic gene abundance as an indicator for MIB prediction, which was verified in other reservoirs.

The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
