Description

The deposited data were collected as part of the research project entitled "Preliminary studies on the treatment of leachates from municipal waste landfills in plant activated sludge systems", financed by the National Science Centre under the Miniatura competition (no. DEC-2023/07/X/ST10/00063).

The main objectives were:

1) to verify whether V-ASP systems demonstrate satisfactory efficiency in landfill leachate treatment, and to assess how HRT can affect the final removal efficiency of selected pollutants and process stability.

2) To investigate the potential of low-cost adsorption materials, zeolite and sunflower husk biochar, to improve the treatment of leachate in V-ASP systems. The adsorption properties of zeolite and biochar in different variants of V-ASP systems were evaluated using FTIR and scanning electron microscope (SEM) analysis to better understand the contaminant removal mechanisms.

Project duration from 30.05.2023 to 29.05.2024. Project carried out at the Wroclaw University of Environmental and Life Sciences.

The attached files have been compressed to *.zip format. The dataset consists of the following files:

The collection contains research results on:

1) treatment efficiency - presented in the publication ”Removal of selected pollutants from landfill leachate in the vegetation-activated sludge process”,

2) characteristics of materials - zeolite and sunflower husk biochar - presented in the publication ”Assessment of changes occurring in biochar/zeolite substrates used in the vegetation-activated sludge process in the treatment of leachate from landfills".

The results obtained using the methods presented in detail in the methodology and supplementary materials to the articles. All reagents for the analyses were provided by MERCK (Germany). Atomic absorption spectrometry (AAS) was used to determine the content of heavy metals according to the ISO 15586:2003 standard. A Thermo Scientific Nicolet iN10 MX spectrometer with an external Nicolet iZ10 FTIR module (Thermo Fischer Scientific) was used for FTIR analysis. A scanning electron microscope with an EDS system (Quanta 250 LEICA EM ACE200, FEI, Oregano, USA) was used to characterize the morphology, microstructure and elemental composition of biochar and zeolite samples. The porous texture was characterized by nitrogen adsorption at 77K (ASAP2020, Micromeritics).
