[...]MBR Package Plant for Sewage Treatment – From Sewage to Pure Irrigation Water A membrane bioreactor (MBR) is a wastewater treatment process combining membrane filtration with biological treatment. This innovative technology offers several advantages compared with the conventionally activated sludge process. Among these advantages are higher biomass concentration, eliminating the needs of secondary clarifiers and improved effluent quality. MENA-Water package plants transform sewage to clear and high quality water. The small footprint of the treatment technology enables the systems to be integrated[...]

[...]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 [...]

[...]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 [...]

[...]Contact Drying of Sewage Sludge Partial drying of sewage sludge for recycling in fluidized bed incineration plants. Water evaporation per dryer: 2 to 6 t/h Dewatered sludge throughput per dryer: 6 to 12 t/h * DR throughput capacity per dryer: 1.5 to 6.0 t/h * Heating medium: Saturated steam up to 10 bar(a) * dependent on inlet and outlet DR Thermal drying of sewage sludge is an indispensable process component to ensure the sewage sludge has the right dry residue. The subsequent mono-incineration of the sewage sludge achieves an enormous reduction in volume and mass and provides for the recovery [...]
