(A) Both at domestic and international level, water and wastewater treatment is an area of great importance and research in order to ensure a healthy environment for the next generation. The project aims to achieve internationally listed high-quality research results in the field of fund, applied and experimental development through the use and broadening of existing research experience in three main research areas. The entire research is based on the knowledge base of the University of Pannonia, its national and international research team, as well as the work of the industrial experts employed in the project. The latter guarantees that the results of the basic research will be further developed, which offer an exportable product that is useful for the industry. The research programme ensures that Veszprém County preserves the regional role of knowledge, while at the same time gaining a competitive advantage in the field of water treatment technologies and strengthening its position on the international market. This R & D & I activity improves Hungary’s innovation performance and thanks to the industrial partners involved, the spill-over effect of smart growth at the domestic level will bring the rise of other regions as well. 3 main directions of the project: 1. Development of a prefabricated small wastewater treatment family, 2. Development of a modular, mobile water treatment system, 3. Development of industrial wastewater treatment family. In addition to the main directions, the most up-to-date areas of genetic, IT, mechanical, chemistry and technological knowledge are present, with the focus of the results being the economically usable product, as well as the knowledge and experience gained in the scientific field. The research project can be divided into three main areas and other sub-areas of significant international interest. 1. Development of a small prefabricated wastewater treatment family The aim of the experimental development is to harmonise the latest biological, photocatalytic, RO and enzyme membrane technologies as much as possible during the development of a small prefabricated wastewater treatment family. To do this, we will first test in laboratory size, then under semi-operational conditions, what combinations and operating parameters bring the highest efficiency. The novelty of the method is that the learning process of AI-assisted control is also supported by the genetic identification of microbiological consortia, which promises significant efficiency gains. 1.1 Control with artificial intelligence based on genetic identification: Both the wastewater treatment itself and the composting of the sludge resulting from it are microbial processes, which, however, cannot be tested by conventional methods, since more than 99 % of microbes cannot be cultured at all. However, microbial composition studies have been revolutionised a few years ago by the emergence of the so-called “new generation sequencing technology (NGS)” based on the genetic identification of the hereditary material of microbes and able to quantify all bacteria (eubacteria and archaea) and fungal species (yeasts, yarn fungi) present in any sample based on DNA based on DNA. With the use of NGS platforms, the whole spectrum of microbial life is revealed to our eyes, not only can we find out what species are present, we get a picture of all tens of thousands of species of quantity, changes over time, and we can even get an insight into the processes they carry out. The use of the method is therefore not only of scientific importance but also of key importance for understanding and further developing waste water technologies. 1.2 Optimum utilisation of water’s heat reserves: Waste water produced in households evacuates 40 % of the energy used to heat water. While this heat provides a living condition for microorganisms in activated sludge systems, it causes significant heat loads in receiving living waters during the winter period, changing the natural conditions and thus the local ecosystem. By recovering waste heat, this can be eliminated and further recovered according to needs (heating or hot water production). In the framework of the project, we will examine which heat recovery solutions can be used and how effective in the planned modular system. 1.3 Application of membrane technology in wastewater treatment: The range of membrane processes that can be used in wastewater treatment is very wide, with microbial electrochemical systems being the most recent novelty in this area. These are cells containing proton selective membranes where the bio-processes involved generate electricity (or biohydrogen) on the one hand and, at the same time, the COD/BOI content of waste water supplied as substrates can be significantly reduced. So with the help of microbial electrochemical cells
