Tank Capacity and Residence Times for an A2O Wastewater Plant in Tokyo

Tokyo's A2O wastewater treatment plant data includes tank capacities and residence times, supporting a study of bacterial community dynamics and nutrient removal. The dataset is 9.1 KB in size, authored by Akifumi Nishida, and was last updated on April 15, 2026. The study used 16S rRNA gene analysis and ion chromatography to monitor bacterial composition and nutrient concentrations across seasonal temperature variations.

Use Cases

• Modeling nutrient removal efficiency based on tank capacity and residence time data.
• Analyzing the correlation between seasonal temperature and nitrification efficiency mentioned in the description.
• Studying the spatial attenuation of wastewater impact on riverine bacterial communities downstream.
• Investigating the stability of core bacterial communities across different treatment tanks over time.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Specific file size of 9.1 KB indicates a focused, manageable dataset.
• Study design incorporates both 16S rRNA gene analysis and ion chromatography for complementary data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 9.1 KB size suggests a very limited scope, likely containing only summary or key parameter data.
