The waste water authority of the Swiss region Lake Zug \u2013 \u201dK\u00fcssnachtersee\u201d- \u201c\u00c4gerisee\u201d operates the waste water treatment plant \u201cARA Sch\u00f6nau\u201c – one of the biggest and most modern waste water treatment plants in Switzerland. Via a canal network with about 75 km main collecting canals, 20 waste water pumping stations and 10 storm water overflows, 20 million cubic metres of waste water per year are led into the central main clearing plant (180,000 inhabitants) of canton Zug.<\/p>\n
Thus \u201cARA Sch\u00f6nau\u201c is not only one of the biggest, but also one of the most progressive plants and absolutely state of the art. By an anaerobic ammonia oxidation the nitrogen containing centrate from the sludge dewatering is pre-treated biologically (Anammox procedure). In this process nitrogen links are at first directly changed into elementary nitrogen (atmospheric nitrogen) and then conducted away.<\/p>\n
Hiller Decanter technology wins against competitors<\/strong> Hiller succeeded in winning an open invitation of tenders issued by planning office \u201cHunziker Betatech\u201d. The criteria for finding the best bidder were defined as follows: \u201cthe most cost-efficient offer and a check of customer satisfaction of already installed plants\u201c.<\/p>\n All competitors had the opportunity of testing dewatering properties of the sludge conditions on site with performance tests. Every company could present its latest machine technology. A requirement which matches with the strengths of our company and so the welcome decision was communicated to us in August 2015.<\/p>\n Hiller met all deadlines \u2013 and could even exceed the required dewatering performance<\/strong> Hiller Centrate Control ensures optimum operating safety<\/strong> Once again we want to say thank you for the pleasant and fruitful realization of the project and are looking forward to a long-term cooperation with \u201dARA Sch\u00f6nau\u201d!<\/p>\n","protected":false},"featured_media":3924,"parent":0,"template":"","news_cat":[],"class_list":["post-3927","news","type-news","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\n
\nHiller is proud of winning a thrilling competition and of having delivered two of their new high-performance centrifuges, type DP 574. We are especially proud that one of the two machines has the Hiller production number 5555 which is very nice for such an important reference plant.<\/p>\n
\nDue to an exemplary cooperation with the local supervision of works by company \u201dHunziker Betatech\u201d, the head of operation of waste water treatment plant – Mr Groub and his qualified and motivated team, supported by another subcontractor, the new plant could be commissioned and was \u201dReady To Go\u201c on schedule in December 2015. Already immediately after commissioning the performance results of the uninstalled machines were exceeded considerably. Due to the constant operating conditions the mobile and temporary Hiller liquid \/ solid separation system could already be uninstalled.<\/p>\n
\nFor the first time ever in use at our customers the patented \u201cHiller Centrate Control\u201c has also been implemented here. This system ensures a continuous optical monitoring of a pre-selectable quality of the centrate water and also as controlled variable for achieving an optimum result in terms of business management! In addition to more operational safety we obtain in this specific case a proven reduction of the polymer consumption in a range from 0.5 to 1 kg more substance\/toDS, which equals a reduction of yearly operating costs by 5 to 10%!<\/p>\n
