[...]Machines for Mechanical Sludge Treatment HUBER offers the complete program of mechanical sludge treatment equipment Screening - Thickening - Dewatering ... from one source Screening - Thickening - Dewatering ... from one source Machines for Sludge Screening Machines for Sludge Thickening Machines for Sludge Dewatering Sewage sludge is continuously generated on municipal and industrial wastewater treatment plants during the process of organic pollutant degradation. Adequate sludge treatment is required prior to disposal and a major pre-treatment step is to reduce disturbing solids and the water[...]

[...]Circular Grit Traps Separation of grit and other mineral materials transported with the wastewater with centrifugal force HUBER Circular Grit Trap HRSF Circular Grit Traps HUBER Vortex Grit Chamber VORMAX Circular Grit Traps Circular and vortex grit traps separate the grit from the wastewater with centrifugal force. Separation of the grit particles is supported by the rotational motion of the wastewater. Due to the radial rotation, the solids are very quickly collected within the centre of the grit chamber from where they can be separated and discharged.[...]

[...]Thickening of municipal and industrial sludges Compact, enclosed design Efficient, reliable and easy to operate Low operation and maintenance costs More than 700 installations worldwide prove the reliability of theHUBER Rotary Screw Thickener S-DRUM. Thickening results > 7 % DR are achieved in typical municipal applications with a polymer consumption of 3 - 5 g/kg. Power consumption is only 35 W/m³, spray water demand only approx. 25 l/m³. Different system sizes are available for throughputs from 20 to 100 m³/h per unit. Design and Function A preceding flocculation reactor with stirrer [...]

[...]Very low polymer consumption High throughput capacity Reliable operation The purpose of sewage sludge thickening Sewage sludge, particularly secondary sludge, is charac­terised by low solids concentrations and therefore big vo­lumes. Good sludge thickening is required as a prerequi­site for the efficient further treatment of sewage sludge, for example in digesters, and is also necessary where liquid sewage sludge is transported to further treatment steps or utilisation. The following criteria are decisive for the selection of the thickening process: Efficiency Performance Reliability Design and [...]

[...]Titting, Germany As a long-standing HUBER customer who is very open to new solutions, Gutmann Brewery from Titting also took a look at our new digital platform. Florian Reinhold, responsible for the maintenance of the wastewater treatment plant at Gutmann, was given access to the customer area via shop.huber.de and immediately found his way around intuitively: ‘I can see our machine here and can see exactly which article I can reorder in the spare parts list,’ reports Florian Reinhold, who has already placed several online orders via our online shop. His feedback on user-friendliness is positive[...]

[...]Energy recovery from wastewater for heating and cooling Modular design Developed especially to be used with all types of wastewater Odour-tight Not easily affected by coarse and floating material Low maintenance requirements Self-cleaning Right below the ground, in sewers, is a hidden and seldom used source of energy: our wastewater. Generally the temperature of sewage is in the range of 12 to 20 °C. Even during winter the wastewater temperature never drops below 10 °C, or only for a few days. This makes wastewater an excellent heat source for the operation of heat pumps. As a link between the[...]

[...]Chemicals dosing is optimal if the flotation system constantly achieves the required performance without overdosing of chemicals and unnecessarily increasing operating costs. In practice, it proves to be difficult to adjust the chemicals dose due to varying volumes and freights. Large-dimensioned mixing and balancing tanks are beneficial but can frequently not be installed due to lack of space. Besides, the investments costs are high for the tanks and the accessory equipment required, such as circulation pumps and aeration systems for homogenisation. The innovative HUBER Chemicals Dosing [...]

[...]Flotation plant HDF S for high solids loads Flat construction with a large water surface of up to 160 m³/h Simple, reliable saturation system using a multiphase pump Machines can be mounted in standard containers as mobile units Suitable for high solids loads and for activated sludge separation as an alternative to conventional secondary clarification Up to 30% operating costs saving when combined with a DIGIT-DOSE Chemicals Dosing system Principle of Flotation: During dissolved air flotation, very fine gas bubbles of 20 ‒ 40 μm are released, which together with the particles present in the [...]
