Genera complying denitrifying phosphorus removal community contribute excellent SND-PR in a pilot cyclic SBR: Effect of DO, settling and recirculation rate on process performance.

This work investigated the role of operational conditions and typical functional microbes to maximize the nutrient removal efficiency of a pilot-scale sequencing batch reactor (SBR) system (100 m/d) that treated municipal wastewater. The pilot system was operated in five phases, including start-up and four runs at variable cycle times (2.0, 1.

Effect of Substituent Groups on the Adsorption Efficiency of Phenols by Activated Carbon Developed by Hydrothermally Treated Phyllanthus Emblica Fruit Stone.

In this study, the novel activated carbon developed from fruit stone, through hydrothermal treatment at low pressure and temperature, was utilized for the removal of 4-nitrophenol, 4-chlorophenol, and phenol from water. The activated carbon produced (AC-HTPEFS) showed a well-developed porosity with a surface area of 569 m g and a total pore volume of 0.342 cm g.

Serosurvey For Measles, Mumps and Rubella in Children and Adolescents with Chronic Kidney Disease.

Objective: Children with Chronic Kidney Disease (CKD) are at increased risk for vaccine-preventable diseases. The primary objective of the study was to estimate IgG antibody titers against measles, mumps, and rubella (MMR) in children with CKD and healthy controls who were previously immunized with measles/ MMR vaccine.

Methods: This case control study was conducted between January 2019 and January 2020.

Emerging contaminants in polluted waters: Harnessing Biochar's potential for effective treatment.

Biochar is a carbon-rich, sponge-like material with intricate functionalities, making it suitable for various environmental remediation applications, including water treatment, soil amendment and, additives in construction materials, anaerobic digesters, and electrodes, among others. Its easy adaptability and low cost make it particularly attractive. This review highlights a range of biochar and surface-modified biochar exhibiting high uptake and degradation efficiencies for a broad spectrum of contaminants, including humic acid, disinfection by-products (DBPs), radioactive materials, dyes, heavy metals, antibiotics, microplastics, pathogens, Per- and polyfluoroalkyl substances (PFAS), and cytotoxins.
