With the aim to monitor 17 pump stations to the sewage treatment plant Dietfurt a.d. Altmühl centrally and automatized, we have retrofitted a large remote maintenance system and implemented it into the existing control system of the sewage treatment plant. In the sewage treatment plant of the city of Bad Tölz the entire automation technology was brought up to the current technical standard. We have extended the remote maintenance, improved the speed and stability of the system and we ensured the reliable supply of spare parts. The wastewater that is generated during the production processes in a dairy must be treated in several steps. With this project we took over the automation of the control systems as well as the complete electrical installation. In Bahr El Baqar (Egypt) the world’s largest solar drying plant for sewage sludge has been completed. We have delivered the electrotechnical control system for the hundred machines, which now turn and dry the sludge and convey it to containers. Sewage sludge must not be used any longer as fertilizer; in dried form, however, it can be used very well as fuel. For this dewatering process there are special belt dryers. We programmed and produced the switch and control system for three belt drying streets.
