Article
Full-text available
The object of research in this work is model aqueous solutions containing phosphate ions. Phosphorus is an essential nutrient for all life forms and determines the trophic state of freshwater ecosystems. The existing problem is that when excessive phosphorus enters water bodies, it causes their eutrophication, and, as a result, the accumulation of...
Article
The solvent sublation method was used to remove Ni(II), Cu(II) and Fe(III) ions from wastewater. The purpose of this work was to develop a mathematical model of the solvent sublation process and identify the parameters that affect the degree of pollutant removal. The correlation analysis was used to evaluate parameters that influence on the process...

The object of research is wastewater contaminated with anionic dyes. Traditional methods of wastewater treatment from dyes are imperfect and inefficient or non-existent. Therefore, the need to develop and implement effective and inexpensive to use and operate dye removal technologies is important. The biggest problem in dye removal is when large vo...
Article
Improving the production efficiency is one of the main management tasks for the pulp and paper industry. This can be achieved through the use of automated planning systems, designed to take into account the features and limitations of particular production. Such systems allow, on the basis of orders received from consumers, a voluminous production...
Article
Introduction. The level of water pollution in Ukraine continues to grow, despite the strengthening of requirements for the treated water, so the existing approaches to the water treatment processes control need to be revised and improved. Materials and methods. Mathematical Programming methods for formalization and solving the optimization problem...

This monograph contains a collection of recent research papers focusing on advancing existing technologies and developing new technologies to improve the environmentally friendliness and save resources during the production of elastic leather materials. The papers are organized based on the type of technological process used to preserve raw hides....
Article
The immobilization performances of Diatomite, Ca(H2PO4)2, CaCO3, Hydroxyapatite (HAP) and Nano-HAP (n-HAP) for Zn, Mn, Pb, and Cd contaminated sediments were investigated by immobilization experiments and evaluated by the European Community Bureau of Reference (BCR) extraction test, toxicity characteristic leaching procedure (TCLP). The result of B...

Project
The main goal of the project is to develop improved learning and teaching tools, methodologies and pedagogical approaches using best practices. As a result, there will be developed skills in multiple use of resources and long-term planning for multiple benefits in such a way that project partners will have harmonized teaching and pedagogical approaches in water related gradual education.
Project
Water H-II is aimed at developing and expanding the project initiative - CPEA-2011/10002 “Water Harmony - Integration of Education, Research, Innovation and Entrepreneurship” (with the financial support of the Norwegian Center for International Cooperation in Education (SIU) on the basis of an agreement with the Norwegian By the Ministry of Foreign Affairs). Also, the creation of a scientific and pedagogical consortium, including 10 partner universities from Belarus, Kazakhstan, Kyrgyzstan, the Republic of Moldova, Tajikistan, Ukraine and Norway, to harmonize higher education related to water resources, in order to increase its relevance and quality. Improving the quality of education is supported by modern teaching tools, teaching methodologies, pedagogical approaches with flexible learning paths, virtual and physical mobility, blended courses, internships, etc. In addition, attention is paid to ensuring the quality of education, the development of research and innovation potential, which are among the regional priorities.
