1.3. Prevention of polluted water entering the water system
MATE considers it crucial to prevent any polluted water from entering the water system, including contamination resulting from accidents or incidents on campus. The university works with specialized laboratories for the regular disposal of hazardous waste. Additionally, strict chemical handling rules prohibit pouring any chemicals into taps, while all other types of contaminated water are directed regional waterwork. The organizations involved in wastewater management are listed in Section 1.1. Water suppliers and services.
Reducing the pollutant content of wastewater discharged into the collecting system
The Environmental Order - Környezetvédelmi Rend of the Szent István Campus (p. 13) states that the following measures should be taken for the technologies of most concern for harmful pollution: for laboratory technologies, the safety data sheets of the hazardous substances and preparations used should be consulted and the safety data sheets should be followed. Thus, as an environmentally responsible organization, we ensure that all polluted wastewater and contaminants are properly managed and directed into the appropriate collection systems to prevent any discharge into the water system. This includes measures to handle pollution caused by accidents and incidents on campus.
MATE conducts research on water quality and pollution management across its campuses, focusing on both surface water and groundwater systems. The university’s studies examine the impact of agricultural runoff, industrial contaminants, and wastewater on ecosystems, aiming to develop sustainable treatment and mitigation strategies. These research efforts integrate laboratory analyses, field monitoring, and innovative technologies, contributing to improved environmental protection and responsible water resource management.
Scientific researches in the framework to the KEHOP-3.2.1-15-2021-00037 project
A BSc thesis investigated the advanced treatment of wastewater generated during sludge processing. The research focused on a two-stage ultrafiltration–reverse osmosis (UF–RO) system, which allowed the removal of suspended solids from clarified sludge water (UF) and reduced ion concentrations (RO). The RO permeate produced clean water suitable for irrigation, flushing, or safe discharge into natural water bodies, potentially improving water quality. The concentrated fraction from the UF–RO system was suggested as a liquid soil conditioner or for addition to similar mixtures to enhance product quality. During the study, the student conducted membrane testing, evaluated optimal operational parameters, and performed analytical characterization of both the feed material and the resulting products, ultimately summarizing the findings and practical implications.
Scientific Student Association research investigated the use of microalgae in wastewater treatment technologies. In the conducted model experiments, the student monitored nutrient removal during a one-week treatment and then examined the water separation of algae by adding different flocculent plants. The settling efficiency was measured at various times and concentrations, and the results were evaluated from multiple perspectives. The research contributed to the development of a nitrogen and phosphorus removal method in which nutrients were transferred from the treated wastewater into a solid phase in an organic form that can be absorbed by plants.
Another study examined the management and utilization of distillery wastewater/ spent mash (brewery or distillery residue), a type of organic waste that presents significant challenges due to its high acidity, organic content, and substantial levels of polyphenols, macro- and micronutrients, and heavy metals. Composting was identified as a viable strategic option for valorising this material, promoting the recycling and stabilization of its organic matter and nutrients. The review analysed various composting methods, including traditional composting, vermicomposting, and co-composting, along with their advantages and disadvantages. To optimize composting efficiency, different materials such as sewage sludge, vinasse, green and animal manure, inorganic additives, straw, municipal solid waste, and other agri-food or animal bio-wastes were considered for inclusion. The use of these materials and mixtures aimed to enhance the composting process, accelerate decomposition, and improve the quality of the final compost.
The WaterGreenTreat project, led by the Institute of Aquaculture and Environmental Safety, adopts a circular‑economy approach to wastewater treatment by developing eco‑friendly, 3D‑printed photocatalysts made from metal‑oxide nanocomposites. These novel structures are designed to remove persistent organic pollutants—such as pharmaceutical residues and textile dyes—from industrial wastewater, enabling the reclaimed water to be safely reused for agricultural irrigation. MATE’s role in the consortium includes conducting comprehensive ecotoxicological testing across multiple trophic levels, both in vitro and in vivo, to assess the safety and detoxification efficiency of the treated water using their specialized infrastructure.
