[...]Amsterdam, Netherlands When the Dutch sewage treatment plant Amsterdam-West was modernised in 2006 it was redesigned for the treatment capacity of 1,000,000 PE. In addition, more than another 1,000,000 PE external sludge can be treated there. In the past, particularly the treatment of primary sludge was a problem in terms of the operating reliability of the entire sludge line. The solids contained in the different types of pre-treated sludge and from the transport tanks cause high wear and lead to unforeseeable maintenance work requirements on pumps, digestor internals and sludge dewatering systems. In order to remove the solids from the sludge four HUBER STRAINPRESS® units were installed and successfully commissioned in 2011 via the company Dutch Spiral. The supply included removal systems and screenings containers. Up to 75 m³/h primary sludge with a solids content of 1 to 6 percent is pumped through each STRAINPRESS® unit. The solids are retained by a conical-shaped screen with a perforation of 5 mm. When the screen surface is blinded with solid material, a filtration resistance develops on the screen surface. When the filtration resistance exceeds a certain pressure difference a removal screw inside the screen drum automatically starts to operate and cleans the screen surface. In the same process step the solids retained in the screen are compressed against a pneumatically operated pressure cone and then discharged. The screened primary sludge is transported to the digestor by the pressure of the feed pump. At Amsterdam-West the dewatered solids with a dry substance content of 40% are dropped into two troughs where the screenings from two machines are collected prior to being discharged into two odour-tight containers. The screenings are incinerated in an incineration plant that is installed directly next to the sewage treatment works. The high efficiency of the HUBER STRAINPRESS® units becomes especially evident when comparing them to the four screens that are installed in the STP inlet and have a bar spacing of 6 mm and width of 4 m each: The screens separate an annual screenings volume of 125 tons dry substance. A downstream screenings press compacts the screenings to a dewatering degree of 25%. In comparison, the downstream STRAINPRESS® units separate 600 tons dry substance a year, which is five times the volume the screens are able to remove. The integrated dewatering mechanism constantly achieves dewatering degrees of 40% and thus can produce a combustible product. Since the STRAINPRESS® is a completely odour-encased system, neither sludge nor screenings cause a corrosive or explosive atmosphere inside the building. The machines can nevertheless be completely opened very easily for inspection or maintenance. Since the installation of the HUBER sludge screening systems at the beginning of 2011 maintenance costs and shutdowns have been reduced significantly on STP Amsterdam-West. The operating reliability of HUBER STRAINPRESS® systems can be witnessed not only on the reference sites Amsterdam and Den Haag in the Netherlands but also on many other sites all over the world, such as Berlin, Barcelona, San Diego, Seoul, Marrakesh, etc. Benefits of STRAINPRESS® Sludgecleaner: High separation efficiency Significantly reduced operating costs Compact, fully enclosed design Proven in thousands of installations[...]

[...]„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. We have already realised two projects (ARA Bern in Switzerland and Lindenschmidt KG in Germany) where, with the use of the HUBER Heat Exchanger RoWin, considerable amounts of energy are successfully recovered from such kind of wastewater with approx. 1% DS through cooling. The figure shows an example layout of such an application for a sewage treatment plant size of 100,000 PE. The example shows that more than 50 kW heat can be extracted from the vapours and passed on to a heat pump that produces approx. 750 kW heat from these vapours which are available to be used to heat digester sludge and/or a building area of up to 25,000 m² (= 3.5 times the size of a soccer field) or for external district heat supply. The investment pays off after a short time and the significantly improved carbon footprint additionally justifies the investment costs. Another positive side effect is that precipitation takes place while the wastewater is cooled so that annoying growth in pipelines is prevented. The generated solids can be removed from the heat exchanger and disposed of separately. HUBER Heat Exchanger RoWin for direct preheating of process water in a hospital A flow of high-temperature wastewater is passed through the heat exchanger through which fresh drinking water flows from the other side. In this case, it is not necessary to use a heat pump as the heat already has a high temperature level. In the university hospital "Klinikum rechts der Isar" in Munich heat is directly recovered from the surgical instruments washers and returned to the washers on the fresh water side. Heat recovery in such a small circuit offers two advantages: First, the systems used are relatively simple in most cases and therefore cheap to implement. Second, the time offset from when the warm wastewater is generated to when fresh water is needed is short. The unique buffer function combined with the patented cleaning of the HUBER Heat Exchanger RoWin makes this application so efficient. RoWin for a win-win The company Lindenschmidt KG in Kreuztal, Germany, is a disposal company for problematic oil-containing materials. Biological degradation of these materials leads to a strong rise of the wastewater temperature in the aeration tank so that cooling is welcome. With the use of the HUBER RoWin Heat Exchanger energy can be extracted from the waster in the bio-system and directly passed on to the waste oil storage tank. This solves two problems at a time: First, the temperature in the bio-system is optimised. Second, fossil energy carriers that would be required to heat the waste oil storage tanks can be saved. A variety of application possibilities in various industries The basic idea of these economical applications for heat recovery from polluted media can also be transferred to for example food industries (preheating of feed water for vapour generation), paper mills as well as disposal companies and other producing industries that generate warm/hot wastewater.[...]
