Objectives of the Research Project
The objective of the project is to develop a treatment process or a combination of treatment processes for wastewater treatment and sludge minimization at remote locations such as cabins or refuges in the mountains. Due to their exposed positions in protected areas or on mountains, a treatment and disposal concept for these huts must take into consideration the following special conditions: Environmentally sensitive locations, difficult access and transport situation, decentralized energy and water supply, low ambient temperature, seasonal operation, varying loads, no trained personnel for operation and maintenance.
Within this research project, the Institute for Sanitary and Environmental Engineering will focus on the following aspects: Determination of sludge quantities and characteristics, sludge stabilization, investigation of gas production and degree of degradation, co-fermentation with kitchen waste, dewatering with mechanical (presses) and natural (drying beds) processes, freeze conditioning, microwave drying, investigation of applying fuel cells using digester gas, development and optimization of small sludge incineration systems.
