[...]Shanghai, China Megacities and their problem with construction waste Example: Shanghai Beside Beijing and Hong Kong, Shanghai is one of the most important industrial locations and market places in the People’s Republic of China. In the recent years, the city has had a remarkable growth spurt. Fifty years ago, about seven million people were living in the metropolitan area Shanghai, today the city has more than 25 million inhabitants. Along with the city’s growth came innumerable building projects with huge amounts of construction waste and other waste products. More and more of such material [...]

[...]Rehau, Germany HUBER Longitudinal Grit Trap ROTAMAT® Ro6 Bio and HUBER Grit Washer RoSF G4E increase operating reliability and reduce operating costs Bioenergiezentrum Hochfranken (BEZ) is an association of the town Rehau, the administrative districts Hof and Wunsiedel and some local companies supplying the town and districts with regenerative energy. Beside different plants from the companies involved, the biowaste fermentation plant is at the heart of the new concept. The fermentation plant treats the biowaste of the munipalities involved, covering nearly 40% of the local primary energy demand. [...]

[...]The aerated grit trap is a very important element in mechanical wastewater treatment. Its task is not only to reliably remove the grit from the wastewater flow but also to retain particulate lipophilic substances (grease) to prevent floatable particles from settling or overflowing in downstream treatment systems. Fine grit of a grain size ≥ 75 µm can usually not be separated by conventional aerated longitudinal grit traps as the rising air counteracts the continuous sedimentation of small particles. Very long, wide and voluminous structures are already required if you want to remove grit of a [...]

[...]Niebüll, Germany 2 HUBER Complete Plant ROTAMAT® Ro5 units for 100 l/s on STP Niebüll in Northern Germany Those who know the regions up in the north will know where the town Niebüll is located: It is a holiday destination in the northernmost part of Germany at the North Sea from where also the motorail train crosses the Hindenburg Dam to the village Westerland on the island of Sylt. These special circumstances naturally played a major role for the engineering office Ivers in Husum when planning the preliminary wastewater treatment stage on STP Niebüll. It had to be taken into account that the [...]

[...]We help you to get rid of fat and grease! Grease concentration in wastewater is usually measured by the content of lipophilic substances. A laborious extraction process is necessary to obtain this analytical value from a composite wastewater sample. Grease contained in wastewater is normally present as a dispersed (suspended) fraction. A small portion of the grease is contained as an emulsion, this can be explained by the use of solvents and rinsing liquors. Depending on the type of sewer (length, drop structures, number of pump stations, screens) it is differentiated between a coarse-particle[...]

[...]Castres, France HUBER's first small grit treatment system in France Castres is a French municipality in the South of France which is located on the river Agout and characterized by industrial enterprises. The best known local enterprise is the pharmaceutical and cosmetics company Pierre Fabre Laboratories which has its headquarters in Castres. In the middle of the industrial zone, not far from the Pierre Fabre Laboratories you will find the sewage treatment plant of Castres. The plant is designed for 95,000 PE and clarifies the wastewater of the population of Castres and of the nearby industrial[...]

[...]Stay on the safe side! The need for security has strongly increased especially in the recent past. This development can be recognized in nearly all situations of life. The security requirements are however especially high where a great many people could be affected very easily. Drinking water supply is an example for such a case. The facilities in this sensitive environment are often in a very poor condition. To identify potential weak points, the authorities recently simulated burglary attempts on public institutions, among them also drinking water supply structures. This campaign lead to [...]

[...]In September 2015, new standards went into force which for the first time refer explicitly to manhole covers made of stainless steel: DIN EN 124-3:2015-09, manhole tops and gully tops for use in vehicular and pedestrian areas Compared to the previous DIN EN 124, several additional tests have been added, such as: Securing of the cover / grating within the frame Skid resistance test Tipping behaviour test, etc. From 2017 on at the latest, relevant products must comply with the new DIN EN 124 standards. Since the transitional period has begun already, it is recommendable to prepare tender specifications[...]

[...]Berching, Germany How it all began... In the 1950s and 1960s, manhole covers in "painted steel" and "galvanised steel" were proven products of the HUBER company and the covers were mainly manufactured for water pipeline construction. At the beginning of the 1970s, the brothers Hans and Karl-Josef Huber, the company owners at the time, recognised the desire and need of many customers for a low-maintenance manhole cover that did not require maintenance work such as regular painting of the surface. The idea of using stainless steel for this purpose was born and was implemented on a trial basis. At that [...]

[...]Basel, Switzerland HUBER products for one of the largest wastewater treatment plants in Switzerland: Together with its Swiss partner company Helmut Breschan AG, HUBER is involved in the expansion of the Basel wastewater treatment plant (WWTP). The Berching-based company is supplying over 200 SD7 manhole covers in various designs, including accessories. The expansion of the Basel municipal wastewater treatment plant is progressing: one of the largest wastewater treatment plants in Switzerland is being expanded and adapted to the provisions of the new Swiss Federal Water Protection Ordinance.
