Abstract:

Due to the existing problems of food security in the world, the work aimed at solving them is highly relevant. As a result of the analysis of various approaches in agriculture and fire protection, the need for integration of technological processes was identified. As part of this, a system synthesis of an agro-fire harvester-airship model was performed, which combines all agrotechnologies and precision farming techniques with the functions of extinguishing fires with atmospheric nitrogen separated by a membrane nitrogen station. The simulation results confirming the possibility of extinguishin

Abstract:

Toilet wastewater is treated and reused on site at Europe's highest membrane bioreactor (MBR), located in a cable car mountain station in the ski resort of Zermatt. Negative impacts on the sensitive mountain environment are minimised by reusing close to 100% of the treated wastewater for toilet flushing. Besides 100% nitrogen removal, 80% of phosphorus was also eliminated. This paper presents operational results, optimisations of sludge management, decoloration and long-term maintenance of biomass in the very low-loaded summer season. From a global view the experiences and results of the proje

Abstract:

In the Republic of Benin, as in many other West African countries, urban areas have experienced rapid population growth in recent years. This situation has led to an increasing demand for sanitation facilities, necessitating regular emptying of these systems. In a bid to reduce health risks and protect the surrounding natural environment, the management of the by-products from these systems has become a significant concern for decision-makers at various levels. This study aims to characterize fecal sludge at the Abomey-Calavi treatment station and suggest a mixed biological treatment approach.

Abstract:

The development of efficient and sustainable water recycling systems is essential for long-term human missions and the establishment of space habitats on the Moon, Mars, and beyond. Humidity condensate (HC) is a low-strength wastewater that is currently recycled on the International Space Station (ISS). The main contaminants in HC are primarily low-molecular-weight organics and ammonia. This has caused operational issues due to microbial growth in the Water Process Assembly (WPA) storage tank as well as failure of downstream systems. In addition, treatment of this wastewater primarily uses ads
