[...]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 [...]

[...]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 [...]

[...]HUBER Screw Conveyor in a closed tube Transport of coarse, fine and compacted screenings, sludge, grit, and solids from industrial processes Customized designed for horizontal, inclined and even vertical transport The HUBER Screw Conveyors are installed for horizontal, inclined and even vertical transport of screenings, dewatered sludge, grit etc. from wastewater treatment plants, or other solids from industrial processes. Gentle movement in an enclosed pipe prevents odor nuisance and dust development. Design and Function The HUBER Screw Conveyors are custom made for the individual product to be [...]

[...]Wastewater fine screening Screenings treatment Grit separation Grit classification Requirements for a complete mechanical wastewater treatment plant Manually operated screens and grit traps are no longer sufficient even for small wastewater treatment plants. The increased demands on biological treatment make it necessary to improve the separation performance of mechanical treatment. Solid material has to be separated as far as possible and removed. Screens with automatic cleaning and integrated discharge are now required. Screenings treatment, such as washing of faecal matter, dewatering and compaction[...]

[...]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 [...]

[...]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[...]

[...]Cable operated coarse screen for: Protection of pumping station Seawater intake Surface water intake Sewage treatment plants The HUBER Coarse Screen TrashMax® is ideal to be used in pumping stations, as first treatment stage of wastewater treatment plants or industrial plants, and in the inlet to power plants. The screen removes coarse and bulky material and therefore protects downstream systems. The TrashMax® excels due to its high-capacity screen rakes and the high operational safety due to efficient and reliable screen rack cleaning. Design and Function The cleaning elements, attached to the[...]

[...]Sewage sludge drying using a heat pump – an environmentally friendly and cost-effective solution for municipal and industrial wastewater treatment The compact containerised solution The HUBER Cold Air Dryer HPS® has been developed to efficiently, safely and cost-effectively dry sewage sludge, all within a ready-to-operate, modular containerised design. Who is the sludge dryer for? Specifically for small to medium-sized sewage treatment plants (10,000 to 50,000 p.e.) If there is no source of waste heat for drying but surplus electricity is available, for example from a solar PV system, the HUBER[...]

[...]Well-proven mechanical preliminary treatment equipment High grit separation efficiency Large scum separator with automatic grease removal Optional grit washing The unique HUBER Complete Plant Hydro Duct ROTAMAT® Ro5 HD combines the benefits of both aerated and unaerated grit traps by using a high-performance, innovative grit trap with a small overall plan area. Design and Function The wastewater flows firstly through an inlet screen that retains, washes, compacts and dewaters the solids contained within the flow. The screened wastewater then passes at a right angle into the grit trap tank where it[...]

[...]With aerated or optionally unaerated grit channel Grit trap designed accordance with international standards Separate grease trap with semi-automatic grease removal (optional) Integrated grit washing (optional) For reasons of operational safety the first step of sewage treatment works is generally mechanical wastewater pretreatment including: Fine screening Screenings treatment Grit separation Grit discharge Separation and removal of fat and grease Integrated grit washing Complete wastewater pre-treatment is essential for ensuring smooth operation in wastewater treatment plants, as it prevents [...]
