Sulfur-doped carbon for enhanced flue gas desulfurization

Synergistic experimental and DFT insights

The synthesis of sulfur-doped activated coke (SAC) using SO2 as an activator enables simultaneous desulfurizer production and sulfur resource utilization. This study systematically investigated the evolution of carbon properties through sulfur doping and the enhanced d ...
Gas quenching granulation is one of the most important modern methods utilized in molten steel slag (MSS) treatment, more positive and accurate simulated methods play a crucial role in guiding the whole gas quenching which dominate the stability, cementitious activity, magnetic s ...
Oxygen is essential for heterotrophic ammonia assimilation (HAA), driving the microbial degradation of organic compounds and ammonia assimilation in aerobic wastewater treatment. However, the mechanisms underlying carbon-nitrogen transformation and microbial community assembly by ...
Food waste leachate is a high–strength wastewater characterized by refractory organics, high–salinity and elevated ammonium concentrations, posing challenges for effective treatment and nitrogen resource recovery. In this study, a novel strategy integrating UV/PMS advanced oxidat ...
Ceramic nanofiltration is a potential one-step treatment for industrial waste streams. It can remove colloidal particles, oil droplets and some organic molecules. The drawback of the technology is that backwash cannot be applied to remove the accumulated cake layer from the membr ...
Marine microorganisms have an inherent advantage in the treatment of saline wastewater due to their halophilic properties. Ammonium assimilation is the most important and common nitrogen conversion pathway in the ocean, which means that it may be a suitable nitrogen removal strat ...
This study aims at applying and verifying the MFI-UF method to predict particulate fouling in RO plants. Two full-scale RO plants treating surface water, with average capacity of 800–2000 m3/h, were studied. Firstly, the MFI-UF of RO feed and concentrate was measured u ...

Ammonium-assimilating microbiome

A halophilic biosystem rationally optimized by carbon to nitrogen ratios with stable nitrogen conversion and microbial structure

The contradiction between theoretical metabolism of ammonium assimilation and experiential understanding of conventional biosystems makes the rational optimization of the ammonium-assimilating microbiome through carbon to nitrogen (C/N) ratios perplexing. The effect of different ...

Nitrogen recovery by a halophilic ammonium-assimilating microbiome

A new strategy for saline wastewater treatment

Wastewater with high salinity is one of the major challenges for conventional wastewater treatment. Although nitrogen management is vital for wastewater treatment, efficient strategies for nitrogen recovery and removal from saline wastewater remain challenging. Here we propose mi ...
