A continuous mixer for many different applications

Gebr. Lödige Maschinenbau

Gebr. Lödige Maschinenbau

The low-maintenance Ploughshare mixer KM (photo) is suitable for processing powdery, fibrous or granular solids, as well as liquids and pastes. Granulation processes can also be carried out with the continuous mixer at minimum dwell time. The continuous mixer is based on the patented, mechanically generated turbulent fluidized-bed process. During this process, Ploughshare shovels rotate close to the wall in a horizontal, cylindrical drum. Their peripheral speed and geometric shape take the mixing components off of the drum wall and toss them into the free mixing compartment from the product bed. Intensive mixing is achieved even at extensive throughputs of material to be mixed. An excellent homogeneity and consistent reproducibility of the final product is achieved during short mixing or dwell times of only 25 to 60 s, says the company. The smallest model has a drum capacity of 5 L and a throughput of 0.25 m3/h, depending on the dwell time and filling level. The largest model has a drum volume of 57,000 L and a throughput of around 1,300 ton/h. Hall A4, Stand 441 — Gebr. Lödige Maschinenbau GmbH, Paderborn, Germany

Digitalization in the water and wastewater industry

Endress+Hauser

Endress+Hauser

In line with a comparable advance in development in industrial production, known as the Industrial Internet of Things (IIoT) or Industry 4.0, the German Water Partnership (GWP) is launching a “Water 4.0” discussion aimed at exploring the significance of this technology-driven change to the water industry. In this context, this company is demonstrating some of its initial application scenarios (photo). This includes measurement instruments integrated with Heartbeat Technology, which tests the reliability of the instrument and helps users to improve their processes. The instruments supply digital diagnostic data, verify performance and monitor process data to create a predictive maintenance and process optimization strategy. Analyzers for monitoring phosphorus and phosphate, as well as new compact sensors integrated with the company’s proven Memosens digital technology, help operators monitor wastewater processes and optimize process control.

Kaeser Kompressoren

The CBS (photo) now brings all the advantages of screw blower technology to lower-flowrate applications. For municipal or industrial wastewater treatment plants requiring compressed air with differential pressures up to 1,100 mbars, the CBS screw blower delivers flowrates from 2.3 to 12.2 m³/min, with power from 7.5 to 22 kW. The CBS is also suitable for applications such as production of aeration air in water treatment and for bioreactors, flotation and fluidization. It is up to 35% more efficient than conventional rotary blowers, and even offers significant energy advantages in the two-digit range compared to other screw and turbo blowers on the market, says the company. One screw blower is so powerful that it efficiently covers the control range of two or three rotary blowers. Hall A1, Stand 143/242 — Kaeser Kompressoren SE, Coburg, Germany

Slash operating costs for sludge dewatering with this centrifuge

Flottweg

Flottweg

The new Xelletor series decanter centrifuge (photo, p. 68) is said to provide better sludge-dewatering performance with lower energy consumption. The rotor, and especially the scroll, have a design never seen before. Consumption of polymer flocculant is significantly reduced in the Xelletor series thanks to an entirely new intake configuration. Depending on sludge quality, the centrifuge can save about 20% on energy while providing significantly better performance over traditional systems, says the company. Additional benefits include: more power, which increases throughput by up to 15%; drier cake, which can reduce the volume of biosolids by as much as 10%; and reduced operating costs by 20% due to lower energy consumption and polymer consumption.

Reduce operating costs with sludge disintegrating centrifuge

Hiller

Hiller

This company’s centrifuges can be operated with an additionally installed lysing device (photo). This lysing device is attached in the area of the sludge discharge openings and uses the existing kinetic bowl energy. This means that the additional power consumption of 0.02 to 0.05 kW/kg can also be kept correspondingly low. The disintegration effects in the thickened waste-activated sludge (WAS) essentially take place by impact and shear forces generated by rotating knife blades in the labyrinth and the lysing chamber at high circumferential velocity. The lysing device consists of a labyrinth with a lysis chamber fitted with window openings. Fork blades fitted onto the centrifuge bowl rotate through the lysis chamber, and these blades are protected against wear with tungsten carbide plating. From the discharge openings of the centrifuge, thickened waste-activated sludge thrown out at high speed flows through the lysis chamber in the axial direction. Using a disintegration process to generate technical and economic advantages for further sludge treatment leads to reduced viscosity and better pumping properties, increased degradation of the organic part, increase in gas yield and improved drainage behavior.
