Overviews of projects

“Despite the many heavy snowfalls that hit the northern Black Forest area last winter, for the first time we can say that we had no scraper downtime in the two secondary sedimentation tanks.”

Tobias Weiß, Technical manager, the Altensteig wastewater treatment consortium

“Our plant technician is enthusiastic because now he can stop constantly worrying about the scraper’s 24 h operation, as was the case in previous years - not even in winter! Another important aspect is that the new Friedrich Krumme GmbH system works entirely without additional energy consumption. After this totally positive experience, all I can say is ‘buy it’ to other water treatment plant operators.”

Mr. Menzel, Treatment Plant of the municipality of Nordwalde

“Krumme installed this scraper track more than two decades ago. Since then, the scraper has been working perfectly, without any problems. I would choose it again at any time.“

Mr. Bartonitschek, Director of the wastewater treatment plant of Blomberg

“Fortunately, during the on-site work, all of the objectives and deadlines were complied with. The works were then successfully completed with a final testing. This is also thanks to the exemplary equipment, tools and materials used by the Krumme technicians.”

Samuel Baier, Director of the water treatment plant, Consortium for the treatment of wastewater of Gäu-Ammer
