[...]India The joint venture A.T.E. HUBER Envirotech continues to grow in the field of sludge dewatering, achieving considerable success with the HUBER Screw Press Q-PRESS®. To provide optimal support for the first commissioning projects in India, twelve of the partner’s service technicians completed two intensive online training courses delivered by the HUBER Service Academy. This laid an important foundation for a smooth project start and the sustainable transfer of knowledge. Deepening technical and process knowledge The first training module focused on the technical fundamentals of the supplied[...]

[...]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[...]

[...]Every wastewater regulation specifies a limit value for ‘lipophilic substances’, which in practice are referred to as grease. As a rule, more than 90 per cent of the total grease concentration is often present as dispersed grease particles and emulsified grease. Conventional grit and grease traps at sewage treatment works can only retain non-dispersed, floatable grease (DWA M760). The remaining dispersed substances are separated in the biological treatment section of the sewage treatment works. Various grit chamber solutions Factory-built grit chambers are often combined with grease traps ([...]

[...]Dublin, Ireland HUBER Technology UK was chosen as supplier of seven bar screens and seven screenings wash-presses for the Dublin Bay Inlet Works at Ringsend. The order also included supply of all control panels for all our machines. The plant’s management selected our multi-rake bar screens RakeMax® because of their low head loss during peak flow, in spite of their small bar spacing. Another selection criterion was their great screenings removal capacity. It also helped that our super-launder screenings presses WAP® SL provide superior washing intensity and compaction capability, resulting in a [...]

[...]Emschermündung, Germany The hydraulic capacity of the wastewater treatment plant Emschermündung is 30 m³/s. This is a gigantic flow, larger than of any other German, perhaps even European, wastewater treatment plant. The wastewater arrives at the plant not via conventional sewers, but its inflow is the river Emscher. The treated effluent of the plant enters the river Rhine. This is the reason why the plant’s name is Emschermündung, meaning “mouth of the Emscher”. The river Emscher flows through the northern part of the old industrial heartland of Germany, the Ruhr region. The Emscher river is [...]

[...]Grit Traps and Classifiers The best solution for any grit separation application Grit Trap and Classifier Product Groups Longitudinal Grit Trap Lamella Grit Trap Circular Grit Traps Complete Plants Grit Classifier For reasons of operating reliability of wastewater treatment plants it is necessary to separate grit, gravel and other mineral materials transported with the wastewater (an average of 60 l from 1000 m³ of wastewater according to DWA Work Sheet M369) from the digestable organic material. Good grit separation prevents operational problems, such as grit sedimentation in aeration tanks and[...]

[...]HUBER Grit Washing Plants and System Components Separation of organics from the mineral particles Grit Washing Plants Wash Drum Grit from grit traps of wastewater treatment plants and grit from sewer and road cleaning are heavily contaminated with organic matter and debris. The high content of organic material, the wide volatile solids ratio of 10 to 80%, is the reason why such grit slurries do not dewater well. The solids concentration remains somewhere between. The common performance criteria for the quality of grit removal are: The capture rate of 0.2 mm diameter grit particles; and the volatile[...]

[...]Minimise wear and increase operating reliability For the operating safety and reliability of wastewater treatment plants, it is necessary to separate the grit transported with the wastewater and other mineral materials from the putrescible organic matter. For this purpose, grit chambers of various designs are used in practice. Depending on the type of grit trap, grease can also be separated in addition to grit. The removal of grit from the wastewater serves to prevent operational troubles, such as grit sedimentation (in aeration tanks and digesters), increased wear (of pumps, stirrers) and [...]
