[...]Sargans, Switzerland High level of user-friendliness increased even further In Sargans, Switzerland's first HUBER Screw Press Q-PRESS ® Q 800.2 was installed in 2017 for dewatering digested sewage sludge. The latest generation of screw press could win the competition against other systems due to its very high operational reliability and user-friendliness, complete stainless steel construction and very low operating costs. The demands on the system are extremely high. An essential factor is the required DR concentration in the dewatered sludge of over 30% with simultaneously clear filtrate quality.[...]

[...]Star, Idaho, USA The Star Water and Sewer District knew change was going to come. The plant’s existing in-channel grinder technology wasn’t just aging, it was obsolete. The unit was also in need of repairs that could force two weeks of downtime. Regardless of what they did to “fix” the existing unit, its performance would lag behind newer screening technology. Consultants and engineers pointed the district to HUBER and its ROTAMAT® STAR fine screen as a replacement that would take the plant into the future. The single-most important result that Star Sewer and Water District Waste Water [...]

[...]HUBER presents the HUBER Multi-Rake Bar Screen RakeMax® CF, an innovative variant of the well-proven RakeMax® system with a Centre Flow screen. The model impresses with its hydraulic throughput capacity by means of a U-shaped bar rack, even with small bar spacings and in narrow channels. It offers an optimal hydraulic utilisation of existing channels and the screen is unsusceptible to grit, gravel and stones. Due to its different design options the RakeMax® CF covers a very wide range of applications, allowing us to respond to the individual needs of our customers and to specific constructional[...]

[...]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[...]
