[...]Bielefeld, Germany Stadtwerke Bielefeld GmbH are a modern multi-utility company. With the city of Bielefeld (50.1%) and Bremer swb AG (49.9%) as partners, their priority is to meet customer and market requirements. With about 1,280 employees and a turnover of 700 million euros a year they are one of the big German municipal suppliers of energy, heat and drinking water. Stadtwerke Bielefeld supply the drinking water for about 320,000 residents and 1,500 industrial companies in the city of Bielefeld itself, plus for about 40,000 people living in the greater Bielefeld area. In 2010, drinking water[...]

[...]Heiligenblut, Austria The Heiligenblut wastewater treatment plant, which has a capacity of 8,250 PE, was built at the foot of the Großglockner, Austria's highest mountain, in 1986. It treats the wastewater of the entire municipality of Heiligenblut (at an altitude of 1,288 m), including Kaiser-Franz-Josefs-Höhe, which is the highest point of the Grossglockner High Alpine Road (at an altitude of 2,369 m). The sewage treatment plant is located next to the Mölltal federal road in the village of Rojach, at an altitude of 1,098 meters. The challenge: limited installation space and high requirements The [...]

[...]Mechanical Sludge Treatment Screening, thickening, and dewatering of sludge for impurities removal and volume reduction to reduce transport costs. Solutions for Mechanical Sludge Treatment Sewage Sludge Acceptance Efficient removal of solids and rags from imported municipal sludge prior to thickening or dewatering. Sludge Screening Sludge screening is used to remove coarse material, solids, and rags and increases the operational reliability of subsequent sludge treatment. Sludge Thickening With mechanical sludge thickening processes, the volume of conditioned thin sludge can be significantly [...]

[...]The first step of operationally reliable and efficient wastewater treatment The separation of solids in wastewater with screens and fine screening systems is the first step in municipal and industrial wastewater treatment. The main task here is to remove all coarse and foreign materials that could inhibit or hinder the function of subsequent wastewater treatment stages. The following factors, among others, must be taken into account when planning an operationally reliable solids separation solution: Maximum required hydraulic throughput Expected screenings quantities Required bar spacing or [...]

[...]Process engineering solutions for the treatment of drinking water For the production of drinking water (especially when surface water is used), physical process steps are often necessary to remove solids of different types and sizes. HUBER has customized mechanical and process engineering solutions for the various applications: Specially developed screens for water abstraction remove all inadmissible coarse and solid matter from the raw water from rivers and seas. If required, suitable devices for fish protection can also be provided. Particularly in the case of machine technology for seawater [...]

[...]Reliable compliance with effluent values In conventional municipal wastewater treatment plants, the final settling tank is the last stage of the wastewater treatment process. The purpose of the secondary clarifier is to allow the activated sludge flocs and the finest suspended solids to settle and to discharge the clarified wastewater into the receiving water as free of solids as possible. Increasing hydraulic loads and changes in the settling behavior of the activated sludge are the reason why wastewater treatment plants often do not reliably meet today's minimum requirements for solids retention[...]

[...]Penzing, Germany Solar sewage sludge drying has become a generally accepted ecological and economical technology. To make the implementation and operation of a solar drying plant a sustainable success, all relevant aspects need to be fulfilled: economic and planning aspects but as well acceptance on the part of the operator and the public. One of the plants that offer both, a perfect design concept and acceptance, is installed on WWTP Penzing-Weil near the Upper Bavarian lake Ammersee located southwest of Munich. About 8,500 residents are connected to this aerobic stabilised sewage treatment [...]

[...]Freystadt, Germany Due to the new regulations and legislation for sewage sludge, disposal costs have doubled for many sewage treatment plants or increased to far more than 100 € per ton original substance. The reason for the cost increase is that the standard solution for meeting the requirements of the new legislation is sludge incineration. Incineration capacities are however unequally distributed and exploited to a large extent, and transport ways have become longer on many sites. Disposal costs can be reduced if the sludge volume is reduced through drying. The Bavarian municipality Freystadt [...]

[...]Using the energy of the sun Solar drying of sludge uses the energy of the sun as a thermal energy source. This provides a very ecological, environmentally friendly, and energy-efficient process for the treatment of sludge from wastewater treatment plants or water purification plants. The basic principle of the process is that the sludge is dried in a greenhouse structure. The sludge can be brought into the greenhouse manually, for example with a wheel loader, or automatically, directly from the dewatering facility by means of special conveying units. In the greenhouse, the sludge must be distributed[...]
