Ion Concentration Data from an A2O Wastewater Treatment Plant in Tokyo

13.9 KB of ion chromatography data from a study investigating bacterial dynamics and nutrient removal in an anaerobic-anoxic-oxic (A2O) wastewater treatment plant in Tokyo. The dataset, authored by Akifumi Nishida and last updated in April 2026, was used to assess nutrient removal effectiveness across seasonal temperature variations and the impact of treated wastewater on the Tama River's bacterial communities. It likely contains measurements of nutrient concentrations like nitrate and ammonium.

Use Cases

• Modeling the relationship between temperature and nitrification efficiency based on seasonal monitoring data.
• Analyzing the spatial attenuation of wastewater-derived bacterial DNA in a riverine ecosystem based on downstream sampling.
• Studying the stability of core bacterial communities in wastewater treatment tanks over time.

Strengths

• Data is associated with a detailed scientific study published on figshare, providing context.
• File size of 13.9 KB indicates a focused, manageable dataset for initial analysis.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and specific column definitions are unknown, requiring manual inspection after download.
• The dataset's 13.9 KB size suggests a very limited scope, potentially containing only summary or example data.
• Column-level documentation is absent; field semantics must be inferred from the description.
