[...]Coarse screens are the protective equipment of a screening system. Their task is not removing the incoming screenings from the water flow, but coarse screens are used to protect downstream finer screening systems (or machine technology in general) in the event that massive amounts of coarse material or extreme-size debris occur. Such unusual events in the operation of a screen include the occurrence of large-volume flotsam (e.g. tree trunks, tyres, etc.), man-sized screenings rolls, suddenly occurring huge quantities of screenings or large debris and sediment loads at the channel bottom. Such disturbing[...]

[...]An innovative building block for your digitisation strategy The main duty of the screens installed in the inlet to sewage treatment plants is to protect downstream machines and systems and ensure perfect operation of the sewage treatment plant. When selecting the headworks screens it is usually assumed that coarse material up to a certain maximum size will occur. Increasingly, however, unforeseen material such as cans, wood pallets, large tree branches or even iron rods are also found in sewers. Although such coarse material should definitely not be present in a sewer, there is no possibility [...]

[...]According to the motto "two become one", the HUBER Multi-Rake Bar Screen RakeMax® CF combines optimally matched technologies in one machine. The result is a unique screen system that impresses with both high reliability and innovative functionality. The HUBER RakeMax® CF is a modified variant of the proven HUBER Multi-Rake Bar Screen RakeMax® with a U-shaped stationary screen rack installed between the two screen frames. The bar rack is arranged in parallel to the flow direction of the wastewater. Whilst the wastewater flows into the open front side of the screen and out through both the left and[...]

[...]Changing from aerobic to anaerobic sludge stabilisation More and more municipalities in Germany are striving to optimise the energy efficiency of wastewater treatment on their sewage plants. Generally, there are two options: energetic rehabilitation or expansion of the treatment plant capacity. An expansion of the treatment plant capacity is possible through the construction of a new biological stage, but is counterproductive in terms of energy optimisation, since an additional biological treatment stage requires a considerable amount of additional aeration energy. This solution also increases[...]

[...]Groß-Gerau, Germany The Gerauer Land waterworks supplies around 65,000 inhabitants in the Hessian district of Groß-Gerau with drinking water. The water supply amounts to around 3.3 million m³ per year. The water supply is ensured by extracting groundwater from their own ten deep wells, then treating it to produce drinking water by means of iron removal and demanganisation, and feeding it into the network via a central pressure booster station. After more than half a century of operation, the valves, pipelines, pumps and technical doors had reached the end of their service life. When renewing [...]

[...]Easy to open by a single person and made of a robust, durable material: these are features of HUBER manhole covers that have been a matter of course for a long time already. But what are other, equally important requirements on a manhole cover? 1. Meets legal regulations and normative standards HUBER manhole covers always meet currently applicable standards, thus providing safety and the required level of protection for the operating staff. All our covers raised from ground are designed and constructed according to the latest version (April 2018) of DIN 1239 ” Coverings for wells, spring water[...]

[...]The regular inspection of installations is an important aspect not to be underestimated where drinking water and wastewater structures need to be maintained as valuable elements of our supply and disposal networks. Regular inspections are the only way to ensure the plants and their peripherals can safely be operated a long time. It is of fundamental importance to early identify defects, damage and weak points by regular inspection so that these can be expertly eliminated as soon as possible. The risks of continuing with run-down equipment are not to be neglected, especially not in the field of drinking[...]

[...]In Germany, Austria and Switzerland, enough water of high quality is naturally available at any time. One could almost forget that our most important resource is highly sensitive and gives life not only to humans and animals but also to germs and microorganisms. There are therefore good reasons to protect our water resources and use air filters in drinking water reservoirs. “We have never always built water reservoirs without air filters. Why should we use air filters now?” You may have heard this provocative counter-question sometimes from a customer when you recommended that he should improve his[...]

[...]Weltenburg, Germany In 1999, Weltenburg Abbey suffered severe damage from exceptional heavy storm floods. Also in the following years they were repeatedly faced with flood problems. In 2002, when the Abbey was restored step by step, they therefore decided to buy a flood protection system. The Abbey and the Water Management Office Landshut together with the architecture office Magerl and HUBER SE developed special flood protection elements. These elements should prevent the ingress of flood water through the nine basement windows and the 55 windows on the ground floor of the buildings along the[...]

[...]In many respects, water is an indispensable basis of life for humans and nature, because without water there is no life and no economic progress. However, increasing population density as well as developments in the industrial, commercial and agricultural sectors pose ever greater challenges for a secure water supply. Increasingly, seawater and river water are being extracted to meet the growing demand. Water extraction from surface waters: removal of pollutants by mechanical purification gaining in importance Due to the increasing extraction of water from surface waters and the simultaneously[...]
