[...]Berching, Germany HUBER Chemicals Dosing DIGIT-DOSE setting new standards for the efficient operation of flotation plants Industrial wastewater treatment cannot be imagined anymore without flotation technology. Flotation ensures that suspended matter, grease and particulate pollutants are effectively removed from production wastewater. If also dissolved pollutants need to be converted to particulate matter, precipitants and flocculants are added. Such additives can enormously increase cleaning efficiency, they are however also the major cost factor in the operating costs for a wastewater treatment[...]

[...]Berching, Germany Not only for critical wastewater but also as an alternative to overloaded aeration tanks and secondary settling tanks of municipal and industrial wastewater treatment plants Secondary settling tanks have to manage the important task of separating activated sludge. With diameters of sometimes more than 50 metres, most of them are horizontal flow systems. The sludge can settle inside while the virtually solids-free clear water runs off through a channel. The control and monitoring of such separation stages is still done visually in most cases through cyclic visibility depth [...]

[...]Hämeenlinna, Finland Maintenance costs caused by wear often impair the economic efficiency of centrifuges. Screw presses offer clear advantages in terms of costs and availability. But the operators of screw presses additionally benefit from other advantages. Decanter centrifuges are one of the most frequently used systems for sewage sludge dewatering. Their well known advantages, such as high dewatering degrees even with high throughputs, are due to the effect of the separation of heavy solids and the lighter water phase in the centrifugal environment with the three thousandfold of the [...]

[...]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 [...]

[...]Munich, Germany "Klinikum rechts der Isar" is the university hospital of TU Munich (TUM). There is an intensive cooperation between the university's research facilities and the clinical centre. About 5,000 employees dedicate themselves to the care of sick, research and science. Every year, about 60,000 patients profit from residential treatment and 245,000 from ambulatory treatment at the highest medical level. With about 30 clinics and departments and about 1,100 beds the hospital is a house of supramaximal care which covers the whole spectrum of modern medicine. Due to the close cooperation [...]

[...]„There is one thing that is for sure: The age of cheap energy is over!“ Nobuo Tanaka, executive director of IEA (International Energy Agency) This describes with few words why it is becoming increasingly important to recover used energy. The below examples of projects that use wastewater and process water heat show how energy recovery can successfully be realised in practice. Energy recovery from vapour water In sewage treatment plants vapour water is generated during the sludge dewatering process and is also present in the wash water of the exhaust air treatment systems of sewage sludge drying plants[...]

[...]The HUBER Heat Exchanger RoWin is unique of its kind. The wastewater heat exchanger brilliantly combines excellent heat transfer and automatic surface cleaning. A screw ensures automatic removal of sediments. The RoWin heat exchanger can therefore be used for any sort of wastewater, though municipal wastewater is certainly the most frequent application. The ‘raw material’ wastewater is taken directly from the sewer or downstream of the mechanical treatment stage on the WWTP. But the thermal energy contained within the wastewater does not get lost on a WWTP. Although the wastewater is in [...]
