Within this project component, the RoeVac© NoMix toilets are tested in a continuous-operation mode and necessary modifications are made. The following document shows how the separation toilets work: In the course of the project several modifications of the technical components of the RoeVac© NoMix toilets were carried out. In spring 2010 the urine separation valves were modified and potential leakages could be minimised. Furthermore, the Bowden cables were optimised. To reduce the deposition of urine scale, the interior of the valve was smoothened. For further information regarding the enhancements please have a look at this presentation: English_summary (1,6 MB) Furthermore, experience from continuous operation are documented and recommendations for technical and organisational enhancements are assessed. The documentation is kept in an operation diary, where data of monthly controls and routine maintenance (every six months) are listed. The results have shown that the average lifetime of a valve is 221 days. The most frequently changed components are the Bowden cable and the valve. The main reason for this is that they are the most intensely used components of the RoeVac© NoMix toilets. The most frequent troubles were caused by urine scale depositions and incrustations. However, these depositions are not just a particular problem in this project, they generally occur in public toilets. To prevent precipitation of urine scale no technical solutions are currently known, except of thorough and regular cleansings with adequate detergents. An overview of the project results regarding the establishment of routines for cleaning toilets and urinals as well as to optimize the toilets were presented at the meeting in August 2010. There is an English summary available which includes the most important slides of this component: |
