Action Karl Imhoff was the driving force in the development and invention of the technical apparatuses and methods of sewage treatment (the trickling - and activated sludge process). Imhoff provided not only significant technical innovations, but also design rules derived from experience in the operation of sewage treatment plants. He wrote a book ''Handbook of Urban Drainage'' in 1906, which today is released in new editions. In its 100-year history, the book has been translated 40 times. It has appeared in a total of 20 languages.

Order Of Merit Of The Federal Republic Of Germany
The Order of Merit of the Federal Republic of Germany (german: Verdienstorden der Bundesrepublik Deutschland, or , BVO) is the only federal decoration of Germany. It is awarded for special achievements in political, economic, cultural, intellectual or honorary fields. It was created by the first President of the Federal Republic of Germany, Theodor Heuss, on 7 September 1951. Colloquially, the decorations of the different classes of the Order are also known as the Federal Cross of Merit (). It has been awarded to over 200,000 individuals in total, both Germans and foreigners. Since the 1990s, the number of annual awards has declined from over 4,000, first to around 2,300–2,500 per year, and now under 2,000, with a low of 1752 in 2011. Since 2013, women have made up a steady 30–35% of recipients. Most of the German federal states (''Länder'') have each their own order of merit as well, with the exception of the Free and Hanseatic Cities of Bremen and Hamburg, which rejec ...

Straubing
Straubing () is an independent city in Lower Bavaria, southern Germany. It is seat of the district of Straubing-Bogen. Annually in August the Gäubodenvolksfest, the second largest fair in Bavaria, is held. The city is located on the Danube forming the centre of the Gäuboden. History The area of Straubing has been continuously settled since the Neolithic. The conquest by the Romans in 16–14 BC had a dramatic impact on the whole region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous 'Römerschatz' (Roman treasure) which was excavated in 1950 and which is shown in the Gäubodenmuseum. ''Sorviodurum'', as the Romans called it, was an important military support base. After the fall of the Roman Empire Straubing became a centre of settlement of the Bavarii, mostly around St. Peter's Church (built in the 9th century) between Allachbach and Danube. According to the customs of the Bavarii the settlement was named after their leade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schleswig
The Duchy of Schleswig ( da, Hertugdømmet Slesvig; german: Herzogtum Schleswig; nds, Hartogdom Sleswig; frr, Härtochduum Slaswik) was a duchy in Southern Jutland () covering the area between about 60 km (35 miles) north and 70 km (45 mi) south of the current border between Germany and Denmark. The territory has been divided between the two countries since 1920, with Northern Schleswig in Denmark and Southern Schleswig in Germany. The region is also called Sleswick in English. Unlike Holstein and Lauenburg, Schleswig was never a part of the German Confederation. Schleswig was instead a fief of Denmark, and its inhabitants spoke Danish, German, and North Frisian. Both Danish and German National Liberals wanted Schleswig to be part of a Danish or German national state in the 19th century. A German uprising in March 1848 caused the First Schleswig War which ended in 1852. The Second Schleswig War (1864) ended with the three duchies being governed jointly b ...

Imhoff Tank
The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage. It may be used for the clarification of sewage by simple settling and sedimentation, along with anaerobic digestion of the extracted sludge. It consists of an upper chamber in which sedimentation takes place, from which collected solids slide down inclined bottom slopes to an entrance into a lower chamber in which the sludge is collected and digested. The two chambers are otherwise unconnected, with the more liquid sewage flowing only through the upper sedimentation chamber and only a slow flow of sludge in the lower digestion chamber. The lower chamber requires separate biogas vents and pipes for the removal of digested sludge, typically after 6–9 months of digestion. The Imhoff tank is in effect a two-story septic tank and retains the septic tank's simplicity while eliminating many of its drawbacks, which largely result from the mixing of fre ...
