The dissertation develops a prototype of a wastewater treatment device designed to remove Congo Red, Naphthol Green B, Rhodamine B, and Methylene Blue dyes used in the textile industry from wastewater. The main object of the study is 10.0 mg/L concentration aqueous solutions of Congo Red, Naphthol Green B, Rhodamine B, and Methylene Blue dyes. The primary aim of the dissertation is to apply electrochemical and adsorption methods to reduce Congo Red, Naphthol Green B, Rhodamine B, and Methylene Blue dyes used in the textile industry from water. The dissertation consists of an introduction, literature review, methodology, and results sections, as well as lists of references and the author’s publications on the dissertation topic. The introduction section discusses the research problem, the relevance of the study, the research object, the research aim, and objectives, the research methodology, the scientific novelty of the work, the practical significance of the results, and the thesis statements. The introduction closes by listing the author’s publications and conference presentations related to the dissertation topic and presenting the structure of the dissertation. The First Chapter is dedicated to a literature review. It provides an overview of the need for wastewater treatment in Lithuania and worldwide, summarizing information about possible wastewater treatment methods and highlighting the advantages and disadvantages of each method. It also presents information about the effectiveness of combined water treatment methods. The chapter ends with conclusions. The Second Chapter presents an experimental research methodology describing the preparation of wastewater samples and the treatment of adsorbents and electrodes. It outlines the conditions required for the experiments, the equipment used, and the reagents. The Third Chapter presents the results of experimental studies. General conclusions of the dissertation are drawn following this part of the dissertation. Nine articles on the subject of the dissertation were published: two in Web of Science indexed journals with citation impact factors, two in Web of Science indexed journals without citation impact factors, one in other international indexed journals, two in conference proceedings indexed in the Scopus database, and two in other international conference proceedings indexed in various databases. Eight presentations on the subject were given at national and international conferences.
