[...]Separation of grit from Wastewater treatment plants and sewer systems Road refuse and oil grit Industrial applications Washout and separation of all coarse material bigger than the perforated plate separation size of the drum. Design and function HUBER Wash Drum RoSF9 for separation of grit from WWTPs and sewer systems, road refuse and oil grit: While wash water is added to pre-wash and homogenise the raw material within the HUBER Wash Drum RoSF9, the perforated plate of the Wash Drum retains all particles bigger than the perforation, which are dewatered and then discharged into a skip. Since [...]

[...]Classifying and washing in one system Reduced disposal costs Low investment costs Over 90% separation efficiency of grain size > 0.2 mm Reduction of organic content to < 5% Also suitable for classified grit trap material from biogas plants The Grit Washer RoSF G4E combines continuous separation and washout of contaminated grit trap material in one plant. Design and function Grit classifying Sediments from the grit trap are introduced in the upper part of the plant as a mixture of grit, organics and water. Due to the low surface overflow rate virtually all particles are separated and accumulate in[...]

[...]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 [...]

[...]Belt filter press for municipal and industrial sludge High-performance belt filter press for best dewatering results Combi-unit: thickening and dewatering in one working process Feed capacity up to 1000 kgDR/h Three sizes available Versatile sludge press High efficiency (low polymer and power consumption) High capacity (due to extended predewatering zone) Application-optimized design Can be combined with the HUBER Belt Thickener DrainBelt unit to further increase capacity The Machines – Design and Function HUBER Bogenpress B-PRESS A new, extended high-performance pre-dewatering zone with chicanes[...]

[...]Dewatering of municipal and industrial sludges Compact, enclosed design Efficient, reliable, automated operation Low operation costs Sturdy, long-life stainless steel sludge dewatering unit Feed capacity up to 500 kgDR/h Two sizes available Extremely sturdy design Especially suitable for industrial sludges Well-proven in hundreds of installations Virtually noiseless operation Design and Function Liquid sludge is flocculated with polymer and pumped into a flocculation reactor where big solid flocks are produced. The flocculated sludge flows into up to two machines installed in parallel. The Screw [...]

[...]Grit classifying and grit washing in a single and compact unit Reduced disposal costs Utilisation of the Coanda effect ensures high grit removal efficiency. Less than 3 % organic content High solids throughput More than 2,000 installations worldwide The HUBER Coanda Grit Washer RoSF4 combines grit classifying and grit washing in a single and compact unit. By using the Coanda effect the process of classifying can be combined with the process of sorting to ensure a continuously high separation efficiency and outstanding washing performance. Design and Function Classifying with the Coanda Effect[...]

[...]Utilisation of the Coanda effect ensures high grit removal efficiency Partly reduced organic content of the grit Maximum corrosion resistance and wear protection Grit classifiers are widely used on sewage works for the removal of grit. Flow conditions ideal for maximum grit removal based on scientific definition have until now been unobtainable. Previously designed plants based on past experience have often suffered from grit carry over due to insufficient retention time caused by undersizing of plant (consequence: deposits in digester, high wear rate of pumps) or conversely classified grit [...]

[...]High grit separation through tangential feed introduction at bottom level High throughput capacity of up to 3,000 l/s (10,800 m³/h) Worldwide well-proven, reliable technology Grit separation from wastewater helps prevent operational problems such as grit sedimentation, increased wear and blockages. Design and Function Grit separation with the HUBER Vortex Grit Chamber VORMAX starts already in the inlet channel to the grit trap. Like in an unaerated longitudinal grit trap the grit sinks downs to the channel bottom from where it is transported into the circular grit trap along with the wastewater[...]

[...]High grit separation efficiency through tangential wastewater inflow Optional with integrated grit classifying screw Compact, space-saving unit Stainless steel tank design Applications Wastewater treatment plants Process water treatment Solids / liquid separation in general Design and Function Separation of the grit particles in the HUBER Circular Grit Trap HRSF is supported by the rotational motion of the wastewater. The separation effect is generated by overlapping of the vertical downward motion and a developing centrifugal force acting on the individual grit particles. The inner tank [...]

[...]High separation efficiency of up to 75 μm Small footprint Integrated floating material separation Ideal for high grit loads The new HUBER Grit Trap GritWolf® is different from space-consuming aerated grit channels as it consists of an aerated and an unaerated grit trap chamber. Applications: New wastewater treatment plants Grit trap refurbishment Pre-treatment for membrane bioreactors (MBRs) Design and Function In the first smaller chamber of the HUBER Grit Trap GritWolf® the wastewater is exposed to medium-bubble aeration. Floatable particles rise to the water surface where they accumulate and[...]
