Almost 20 years ago, the sewage treatment plant in the Bavarian town of Gundelfingen on the Danube was one of VTA's first customers in Germany. For plant manager Johann Kerler, there was no question as to who he should turn to when it came to replacing an ageing polymer plant. "We've always had good experiences with VTA," says the experienced practitioner, whose sewage treatment plant is now running a new Eurodos two-chamber tower system.
Less consumption & costs
The system delivers the selected polyelectrolyte solution fully automatically in the optimum maturing time. The high level of efficiency pays off: "We now consume less, which has clearly paid off," says Johann Kerler. A liquid concentrate is currently used as the polymer, but it is easy to switch to dry granulate if required.
Another strength of Eurodos also came into play in Gundelfingen: the system was manufactured in such a way that it fits into the designated space without any major conversion work. The system was delivered complete with control system, installed by the Gundelfingen residents themselves and put into operation without any problems: "We switched it on and it worked," explains Dipl.-Ing. (FH) Tobias Bühler, Head of the Civil Engineering Department of the Gundelfingen administrative community. The system has been running since the beginning of September. "Flawlessly", as he emphasises.
VTA service "extraordinary"
Plant manager Kerler also particularly appreciates the fact that VTA has succeeded in finding a polymer that can be used for both thickening and dewatering. "One product for both applications makes logistics and storage much easier," says Kerler.
