[...]Gessen, Germany When membrane technology solutions appeared on the market for the treatment of municipal wastewater, the requirements on mechanical wastewater treatment systems changed fundamentally. Conventional screens with their bar spacings or perforations of 6 to 10 mm were no longer sufficient for the membrane bioreactors used today. The efficiency of one-dimensional screens such as wedge wire screens, especially the removal of hairs and fibres, turned out to be insufficient to guarantee the safe operation of membrane plants. It became necessary to develop a new type of two-dimensional mesh[...]

[...]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[...]

[...]Guelph, Canada “Nothing slips by the RakeMax®. Its operation is absolutely flawless. After three years, we look at the components in amazement because they are ageless – it’s as if they were just installed yesterday.” Majde Qaqish, Project Engineer for the City of Guelph WWTP It had become obvious to The City of Guelph that it was time to replace several of the components in its treatment process. Project leaders also wanted to take the opportunity to upgrade its treatment processes by implementing leading edge technology. Working with consultants, the City thoroughly researched solutions to [...]

[...]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 [...]

[...]Berching, Germany On the basis of the worldwide known and well-proven system of HUBER ROTAMAT® fine screens with wedge wire screen basket we developed the ultra-fine ROTAMAT® Perforated Plate Screen RPPS with perforated plate. The two-dimensional screen (perforated plate) ensures the reliable removal of hairs and fibres and avoids that: fibres and hairs hinder the stable operation of membrane plants and increase maintenance requirements, these materials tend to entangle on the membranes and lead to reduced membrane plant efficiency these products form tresses in the wastewater treatment plant, [...]

[...]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 [...]

[...]Plymouth + Maer Lane, Great Britain South West Water had been looking at alternative sludge dewatering technologies with lower TOTEX to potentially replace existing veteran centrifuge assets and tasked their preferred contractor Kier Utilities to offer solutions for the Plymouth Central and Maer Lane WwTW’s. HUBER worked closely with Kier Utilities, undertaking trials to demonstrate the HUBER Screw Press Q-PRESS® to South West Water operations who wanted to touch and feel the machine and satisfy themselves that the machine was simple, robust and easy to operate. The trial data not only satisfied[...]

[...]Beijing, China 1. General During the past 20 years China has significantly stepped up its efforts to improve wastewater treatment. Already 3,243 sewage treatment plants were built until June 2012. These state-of-the-art plants clarify an average daily amount of 130 million m³ wastewater. Frequently, however, problems occur especially with sludge digestion due to sediments which hinder optimal digestion and cause wear on the sludge dewatering systems. The problems are caused by the numerous building projects going on in China's cities. A lot of debris, grit and silt, i.e. a lot of inorganic material[...]

[...]Salt Lake City, USA Solar drying of sewage sludge is a technique that is increasingly used to reduce sludge disposal costs and at the same time protect the environment. Today, operators of even medium-sized and large wastewater treatment plants from all over the world appreciate our innovative and reliable solar dryers. The HUBER Solution for sewage sludge drying with solar energy is working with a continuous drying process, that is odourless due to complete restacking of the sludge. Its unique combination of sludge turning and transport performs both spreading and turning of the sludge as well [...]

[...]Beside other elements, phosphorus is essentially required for cell building and is mainly mined outside Europe. Our phosphorus resources are limited. Their price will therefore rise significantly in the future. Phosphorus is a main component of fertilisers and ends up in our food chain either directly via plants or indirectly via animal products. In the human organism phosphorus, as adenosine triphosphate (ATP), has the role of the energy supplier for our cells. About 2 g phosphorus per capita are flushed down the toilet every day. The phosphorus compounds contained within wastewater are [...]
