Περίληψη της διάλεξη​ς
Ecological sanitation concepts for decentralized treatment of waste and wastewater are more and more considered. The reason for this approach is between others the knowledge that resources are limited and solutions should encounter the aspects of sustainability. Depending on the region lacking recourses may be fertilizer, energy as well as water. In addition no waste and wastewater treatment may be available in this specific region. Not only under these conditions eco-sanitation systems may be of great advantage.
In this presentation the background of decentralized systems will be explained and different concepts for varying applications discussed. As a basis for these innovative concepts selected test results are presented. As an example for the application of such a concept a hotel complex for 1000 guests is chosen. The essential element of the concept promoted here is the separate collection and treatment of the individual substance flows. The core technology is the anaerobic co-fermentation of blackwater and organic kitchen residues. The treated residues have a large potential to be utilised as fertilizer and as soil conditioner in agriculture or landscaping. Separately collected grey-water is treated by nano-filtration so that the permeate can be reused e.g. for irrigation or flushing toilets.
