[...]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[...]

[...]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[...]

[...]Designed in accordance with DWA standards or customised design Available with or without aeration Optional separate grease chamber with automatic grease removal Manufactured entirely in stainless steel Grit separation from wastewater will prevent operational problems, such as grit sedimentation, increased wear, and blockages. Design and Function Grit separation The grit trap design and dimensioning are fully compliant with DWA recommendations or according to customer requirements. The grit trap is available as an aerated or unaerated unit. The decision on when to use the aerated or unaerated [...]

[...]Super Launder Wash Press for disposal cost reduction Volume, weight and disposal cost reduction of up to 85 % Compaction up to 50 % DR High washed screenings quality of (< 20 mg BOD5 / g DR) Reduction of disposal costs by up to 10 % compared to simple wash press systems The HUBER Screenings Wash Press WAP® SL operates in a batch mode. Screenings either drop into the wash press trough directly from a screen or conveyor, or they are flushed into the trough through a launder channel. After a batch of screenings has been fed, the trough is filled up with wash water and agitated for an adjustable [...]

[...]Simple process for the removal of trace substances (fourth treatment stage) No shutdowns necessary for cleaning Reuse of the activated carbon Especially municipal sewage plant effluents are among the most critical paths of entry for micropollutants into surface waters. Many of these so-called trace substances are hazardous to the environment and health, are not readily biodegradable and can accumulate in the environment. With the HUBER Active Carbon Filter CONTIFLOW® GAK, HUBER has developed a versatile and reliable key component for the removal of trace substances (fourth treatment stage), which,[...]
