Biosorption Study of Triclosan and Benzalkonium Chloride in Drainfields

A 220.0 KB dataset from a study exploring the role of biofilm and soil grain surface chemistry in contaminant sorption within on-site wastewater treatment systems. The dataset, authored by Adriana Alvarez and last updated in April 2026, contains experimental results from saturated sand column transport tests and quartz crystal microbalance with dissipation (QCM-D) measurements for two antimicrobial contaminants.

Use Cases

• Modeling contaminant breakthrough curves based on sorption behavior described in the study
• Analyzing the impact of biofilm age on contaminant retardation based on the 1-day and 3-day biofilm experiments
• Investigating extracellular polymeric substance (EPS) deposition dynamics using the QCM-D sensor data mentioned
• Studying electrostatic interactions between contaminants and coated surfaces based on the BAC deposition findings

Strengths

• Data includes results from controlled experiments with and without biofilms of specified ages (1-day and 3-day-old)
• Findings are supported by two analytical techniques: column transport tests and QCM-D measurements
• Dataset is focused on two specific contaminants with distinct properties (hydrophobic and amphiphilic)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The experimental scale is limited to laboratory column tests
