[...]Constance, Germany Lake Constance, with a water surface of about 536 km² the largest lake in Germany and the largest freshwater reservoir in Central Europe, has been used for the drinking water supply of the city of Constance for more than 110 years. Due to the already excellent quality of Lake Constance water, the waterworks can provide up to 50 million litres of drinking water for the Constance region every day with comparatively few treatment steps. Excellent drinking water quality through microfiltration, ozonation and sand filters The raw water is pumped out of Lake Constance from a depth[...]

[...]Screw presses have been proving their worth for many years at wastewater treatment plants with population equivalents ≤ 100,000 mainly because the simple operating principle offers advantages compared to other continuously operating dewatering units such as decanter centrifuges: The use of the sludge feed pressure (0 – 300 mbar) as a control variable enables automatic adjustment of the machine and flocculant settings to fluctuations in the sludge consistency. Time-consuming readjustments by the operator are thus reduced to a minimum, and the dewatering system can typically be operated unattended[...]

[...]Prepared for the future with HUBER Retrofit Service The ravages of time not only affect the machine technology, but also the associated switchboard and control system. As a result, failures and malfunctions occur more frequently, especially on the sensitive PLC (programmable logic controller) components. With outdated hardware, a standstill in the near future is unavoidable. Function and operational safety are no longer guaranteed. Moreover, the manufacturers of the PLC hardware are already focusing on new technologies (IoT, Industry 4.0, etc.). This means that spare parts procurement is no longer possible[...]

[...]Basel, Switzerland Wastewater as a heat source for heat pump systems represents a highly efficient energy source and energy sink. Its use is however often limited to big sewer diameters and high flow rates. This article presents an alternative to the use of heat from sewer wastewater: the use of the exhaust heat of locally generated wastewater as a regenerative and sustainable energy source for the production of service water and heating buildings, like in the example of the old-age home Hofmatt in Switzerland that is described below. Introduction Due to the ever improving quality of building [...]
