Andritz Environment and Process Business Area covers a comprehensive range of technologies, products, and services for mechanical and thermal solid/liquid separation for municipal applications and major industries, such as coal and mineral processing, chemical/petrochemical, and food processing. The Business Area is a global leader in this field and offers comprehensive support from the design to the manufacture of key components for sludge thickening, dewatering, drying, and incineration as well as erection and start-up of turnkey plants, including automation and safety engineering. The large installed base of Andritz products and systems, including more than 10,000 centrifuges and over 100 sludge drying plants worldwide, is serviced from dedicated Andritz service centers in Europe, the USA, and Asia.
Over the past 5 years, through complementary acquisitions and extensive R&D, the Environment and Process Business Area has established itself as a global leader in solid/liquid separation technologies and offers the most extensive range of mechanical and thermal dewatering equipment. Since development of the belt press technology in the early 1970s, Andritz has been the technology leader in sludge dewatering equipment. Following the Sprout Bauer purchase in 1990, screens and sieves were integrated into the product portfolio. The production rights for pressure and vacuum disc filters were purchased in the 1980s, and for centrifuges and drum drying equipment in the early 1990s (with the purchase of Guinard and TCW, respectively). The purchase of Swiss-based 3-Sys AGat the end of 2002 contributed belt drying technology to the Andritz portfolio, for drying of sludges, any kind of waste, and also products such as biomass by means of waste heat at around 100�C, thus saving primary energy. A total of three acquisitions marked the year 2004, a turning point for the Business Area. The purchase of Bird Machine provided Andritz with the full range of Bird and Humboldt process centrifuges, which were added to the sludge centrifuge portfolio. It made Andritz one of the leading suppliers for petrochemical and also for ore and mineral treatment equipment. The proven Rittershaus and Blecher filter presses, also on the range of Bird machines, provided access to this traditional dewatering technology field. Just 7 months later, Andritz bought the filtration business from Netzsch and thus became market leader for filter presses. The excellent sales organisation of Netzsch filtration provided us with direct access to important markets in South East Asia, South America and India. At the end of 2004 Andritz took over the drying technology section of VA Tech Wabag in Ravensburg (formerly Escher Wyss and CT Umwelttechnik), a leading supplier of fluid bed systems for drying and cooling industrial bulk materials. Complete systems, consisting of dewatering and drying, for instance for the petrochemical industry, can now be offered. Acquiring Lenser Filtration in 2005 was a further logical step toward significantly strengthening Andritz filtration know-how. Andritz is now able to offer all technologically relevant filter press components from a single source. Lenser will remain an independent organization within the Andritz Group, which will enable it to continue acting as world leader in the supply of filter plates. Environment and Process has current Sales of over 300 million EUR per annum, with sludge treatment accounting for some 50 per cent. The other half is contributed by different mechanical and thermal solid/liquid separation processes in the petrochemical, chemical, mineral handling and food industries. An important role is played by customer service during the plants’ lifecycle. Nearly a third of Sales is due to spare parts, service and maintenance business. Sixteen specialized service and repair centres form a complete after-market network.

The Fine Screening Technology
|
| Andritz Centrifuge Decanters Industrial technology perfectly adapted to the treatment of wastewater sludge CENTRIFUGATION is your guarantee for: Best performance (dryness, capture rate…) Continuous and fully automated sludge dewatering Polyvalence of operation (dewatering, thickening with or without polymer…) Optimum flexibility (adjustment of operating parameters while running) Lasting robustness Compact design and low space requirement Andritz, the specialist for solid/liquid separation for over 50 years, offers you the right solution for your needs. |
| Belt Filter Presses PowerPress Series The best technical and technological solution for large municipal and industrial sewage treatment systems. Robustly designed in a stainless steel frame are a prerequisite for a long useful life. Principle of Operation Features Optimum pressure increase up to 1.2 bar by 11 S-rolls Sturdy frame design in stainless steel (1.4301 or 1.4571) Variable speed drive for the upper and lower belts High-quality roll covers made of rubber or polyamide and roll bearings with double V-ring sealing Belt cleaning with stainless steel spray pipes, optionally with internal cleaning brushes to keep the shower nozzles clear Separate discharge of filtrate and belt wash water for wash water recycling |
| Chamber Filter Presses Traditional recessed chamber filter press operation employs a steady increase in pressure over time as the cake thickness increases, in order to achieve the optimum combination of chamber filling and cake dryness. At a significantly reduced filtrate rate, the filtration is stopped, the press discharged and a new cycle started. Chamber filter presses are reliable and robust in many different applications. The plate pack consists of uniform chamber plates with a recess of 15 - 50 mm to receive the filter cake. A chamber plate is a combination of a filter plate and two frames in once piece. The standard material for chamber plates is Polypropylene. Possible operating pressures: 6, 15 and 30 bar. |
| Hyperbaric Pressure Filter The continuous dewatering system for low final moisture & high capacity. Available as disc filter with up to 168 m² filtration area. This filter exceeds the user's expectations! The HBF proves its excellence compared to conventional vacuum disc/drum filters or various batch processes particularly on extremely fine-particle slurries. The totally enclosed system offers large filter areas at low space requirement, because the specific capacity is up to 10 times higher then on vacuum filters. The resultant low moisture content can otherwise be obtained with batch-type filters only. |
| Membrane Filter Presses During the initial phase of the filtration cycle, so-called “fill and filtration” the process is similar to the chamber filter press. After reaching a predefined pressure, usually around 4-10 bar, depending on the sludge characteristics, sludge feeding is stopped and the membranes slowly inflated, using either water or air as squeeze medium. The cake is hereby compressed and dewatered further. This process is continued until the filtrate flow reaches a preset minimum limit. Then the squeeze medium is relieved and the cake discharged. Membrane filter plates are designed just like the previously described chamber plates. A flexible membrane is fixed to the support body. Materials for the membranes include Polypropylene, synthetic rubber (for example NBR, EPDM) or thermoplastic elastomer (TPE). Special materials such as PVDF are also available. The membrane is impermeable and serves to compress the cake within the chamber after the filtration process is complete. Liquid or gas (compressed-air) can be used as membrane inflation media. In order to guarantee maximum protection for the membrane filter press, we use special safety systems for the various membrane inflation media. Inflation pressures up to 30 bar, and in special cases even higher, are possible. |
