As HUBER is a global market leader in the field of mechanical wastewater treatment, we will of course show our latest further developments of screens as well.
In addition to the latest version of the world-renowned HUBER Multi-Rake Bar Screen RakeMax®, which will be on show in the different versions RakeMax® HF, RakeMax® J and RakeMax® Hybrid, other proven HUBER screens will be exhibited, such as the HUBER Belt Screen EscaMax®, the HUBER Coarse Screen TrashMax®, the HUBER Band Screen CenterMax® and the HUBER Rotary Drum Fine Screen ROTAMAT® systems.
At IFAT 2020, HUBER will show for the first time its newly developed HUBER Multi-Rake Bar Screen RakeMax® CF. This innovative screen opens up completely new possibilities in the field of mechanical wastewater treatment as it features a worldwide unique U-shaped bar rack through which the wastewater flows from inside to outside. Due to this design, the HUBER RakeMax® CF enables high hydraulic throughput rates even with small bar spacings and narrow channels, thus allowing the optimal hydraulic utilisation of existing channels. Further advantages include high separation efficiency and defined meshing of the cleaning rakes with the bar rack, resulting in a high operational reliability.
As a special IFAT highlight we will present the worldwide unique HUBER Safety Vision system. This innovative contaminant detection system for screens uses high-tech sensors to continuously measure the form and size of the coarse materials transported by the screen rake. Whenever the system detects any impermissible coarse material, the screen will be stopped and a warning message sent to the plant operators. Unintentional blockage or damage of the screen or downstream units is reliably prevented by the contaminant detection system. Moreover, the system is able to record the amounts of separated and discharged screenings in real time.
As a specialist for solids-liquid separation, HUBER has intensely been engaged in, among other, the field of grit separation for decades. With the newly developed HUBER Grit Trap GritWolf® HUBER is setting new standards in grit separation. Due to optimized inflow conditions combined with the advantages of a lamella separator, the HUBER Grit Trap GritWolf® is able to separate 90% of grit of grain size ≥ 75 µm.The new GritWolf® grit trap is available in several sizes for flow rates from 160 m³/h (1 MGD) to 3,150 m³/h (20 MGD).
With the HUBER CarbonWin® System, HUBER offers an interesting possibility of retrofitting sewage treatment plants to change from an aerobic to an anaerobic sludge stabilisation process. The first process step of the HUBER CarbonWin® System is a mechanical treatment stage followed by a grit and grease trap. A HUBER Drum Screen LIQUID is installed downstream of this assembly. The effluent from the drum screen is fed to the aerobic treatment system, whereas the separated fine screenings are thickened and passed on to anaerobic treatment in a digester.
