PURPOSE, MAIN PARAMETERS
The subject of the "Overhaul of hyperbaric pressure filters no. 1 – 4 at the ČSM treatment plant" was complete renewal of the entire equipment of 4 filters, originally manufactured in 1993 by Andritz, A.G, Graz, Austria. The repair included complete replacement of the technological equipment inside the over-pressure part of the filter, except for the central shaft which was only repaired. The pressure vessel was completely reconstructed. Furthermore, the drain from the filter was repaired and all pipelines completely replaced which transport the necessary media to and from the filter. At the same time all sensors and probes were replaced, including the replacement of all cabling. The repair also included delivery of a new control system.
The goal of the repair was to ensure the originally designed output of the filter of 50 t/hour which could not be achieved due to the long-term wear of the filter. In addition to the output, the guaranteed parameter of the repair was the humidity of the resulting product which was not allowed to exceed 17%.
