The WWTP Morgental, located in the far northeast of Switzerland on Lake
Constance, is the drinking water reservoir for more than 4 million inhabitants in
Germany, Austria and Switzerland. The WWTP in the village of Steinach ensures the
water purification of 8 communities, located in the cantons Thurgau and St. Gallen.
Therefore, a mechanical sludge dewatering, running economically and smoothly is
even more important.
In winter 2015, a comparative performance test with well-known decanter
manufacturers as well as one screw press manufacturer was carried out and
documented by the engineering firm Hunziker & Betatech. In the following tender,
only the results, proven in the previous test, could be guaranteed. The Hiller GmbH
reached the best results of all attendees and could thus guarantee the best
performance values. So, the Hiller GmbH won the tender as economically best bidder
with their decanter type DP484/1012/SD. Meanwhile, the plant is completed and
successfully activated. The guaranteed performance values are already confirmed in
the stationary operation, too. Since then, the Hiller decanter ensures an efficient
dewatering at the WWTP in Steinach. In the meantime, it was taken over by the
customer and according to the operator, the present operational experiences are very
satisfying and the Hiller support is very competent. “The Hiller GmbH is always
available and works solution-oriented”, confirms the customer.
