[...]Wastewater and sludge treatment for the production and processing of textiles and leather Save disposal costs Clean wastewater Minimise residues Separate solids Reduce operating costs Recover wastewater heat Save primary energy Wastewater from textile and leather industries contains high loads of solids, particularly fibres and hair. Washing the raw materials also causes a lot of grit to get into the wastewater. The wastewater is usually highly discoloured and contains high BOD and COD loads, so heavy pollution charges have to be paid. It is therefore economical to reduce these loads on site to such a degree that the wastewater can be discharged to the public sewer system or even directly into a water course without having to pay fees for heavy pollution. While small plants only have to separate solids, larger facilities also reduce the COD and BOD loads. Due to the large water consumption, it is often economical to treat the wastewater so well that it can be recirculated as process water. HUBER products and solutions for your requirements HUBER Complete Plant ROTAMAT® Ro5 units are used for mechanical pre-treatment of process water or wastewater. This type of plant screens out larger solids and separates settleable materials such as grit in the integrated grit chamber. The separated grit can be cleaned from organic contaminants in a downstream HUBER Grit Washer . The pre-cleaned water can then be further treated with a HUBER Fine Screen to remove fine fibres and hair. A chemical-physical treatment stage with the HUBER Dissolved Air Flotation Plant HDF further increases cleaning performance. Solids and grease are largely separated as flotate sludge. BOD and COD concentrations are thus significantly reduced, so that the effluent can be discharged into the public sewer system. HUBER Thickeners and HUBER Screw Presses are available for thickening and dewatering of flotate sludge and excess sludge. With the HUBER Heat Exchanger RoWin , the often very high wastewater temperatures can be reduced and the heat thus recovered can be used for preheating process water or heating buildings. As one of the world's leading suppliers, we also solve your wastewater treatment challenges with our proven machines and plants. Our solutions for your challenges: COD, fat and solids reduction Reliably comply with discharge limits Reduce operating costs for wastewater treatment Reduce disposal costs for waste and sludge Recover wastewater heat and reduce wastewater temperature Access solutions for manholes and tanks[...]

[...]Water purification and residue treatment for paper and pulp production and wood processing Saving disposal costs Minimising residues Treating process water Screening out fines and fibres Cooling wastewater Recovering heat Treating process and river water The paper, pulp and wood industries traditionally use large quantities of water, which in turn generates large quantities of wastewater. These must be treated accordingly for discharge. In order to further reduce fresh water requirements and costs, water recycling is also being pursued. In addition, the minimisation of residual materials such as process sludge also plays a major role. Ideally, residual materials can be recycled directly on site, e.g. after drying. As one of the world's leading suppliers, we offer proven machines and systems to also solve your challenges in wastewater purification, water treatment or the volume minimisation of residual materials up to their recycling - at low costs and short payback times. HUBER products and solutions for your requirements For cooling or process water, river water or surface water is often used, which first has to be pretreated. For such requirements we use our HUBER screens and screening plants for water intake applications. Grit and gravel can be reliably separated using HUBER Grit Traps or HUBER Complete Plants . Our HUBER Drum Screens are ideally suited for fine screening up to 0.2 mm and offer superior separation performance as well as high hydraulic throughput. Residual materials (e.g. separated process sludges or excess sludge from biological wastewater treatment) are treated with HUBER thickening or dewatering machines, thus saving transport and disposal costs. With HUBER Belt Dryer BT , dewatered biosolids can be dried to a dry residue of more than 90% DR and thus be reused as fuel. Existing heat sources are used for this purpose. For the removal of fines or paper fibres, as well as for the reduction of particulate and colloidal COD (or as pre-treatment or secondary clarification), HUBER Dissolved Air Flotation Plants are used. This allows the process water to be further treated or the resulting clear effluent to be discharged into the sewer. The specially developed self-cleaning HUBER Heat Exchanger RoWin cools wastewater and effluent before it enters biological treatment or is discharged. Recovered heat can be reused. We are your competent partner, from the treatment of raw water to process water and water recycling to the disposal and recycling of screenings, process sludge and biosolids. Our solutions for your challenges: Water intake COD, fat and solids reduction Reliably comply with discharge limits Reduce operating costs for wastewater treatment Reduce disposal costs for waste and sludge Recover wastewater heat and reduce wastewater temperature Access solutions for manholes and tank[...]

[...]Maximum retention of fibres and hair Operating reliability for membrane bioreactors Maximum COD / BOD 5 reduction rates Mechanical pretreatment is required for both municipal and industrial wastewater in order to remove coarse materials and separate floating, settling and suspended solids. Depending on the method of wastewater treatment that is applied the mechanical pretreatment system must fulfil different requirements in terms of separation efficiency. Special plants which operate according to the MBR princi­ple put the highest demands on the mechanical pretreat­ment system as all coarse material needs to be removed. A cost-efficient solution must not only achieve the requested separation results, it must also provide high throughput capacities combined with maximum operat­ing reliability. Design and Function The characteristic feature of the HUBER Drum Screen LIQUID is its screen basket which is horizontally installed in the channel or in a tank. The wastewater to be treated flows through the basket from inside to outside. Whilst the wastewater flows through the open front into the screen basket, solids are retained within the drum. A special sealing between the channel and the front-end screen basket opening prevents unscreened wastewa­ter from passing through the screen basket. The solids settling on the drum surface lead to gradual blinding of the surface. As a result, the water level upstream of the screen rises. When the predefined maximum water level has been reached, the screen basket starts to rotate around its axis to clean its surface. At its crown a spray nozzle bar sprays water onto the drum surface from outside to remove the solids and flush them into a trough inside the drum basket from where the screenings are discharged by gravity. The screenings can optionally be pumped to a higher level. High pressure cleaning For preventive basket cleaning an innovative automatic high pressure system can be integrated as an option. The spray nozzle head rotates automatically due to the water pressure and moves linearly along the full length of the screen basket to clean the complete basket thoroughly and efficiently. Water demand and operator attendance are reduced to a minimum. Reliable sealing Every system is only as good as its sealing system in the inlet of the machine. A special PU sealing is therefore integrated in the HUBER Drum Screen LIQUID to ensure that no unscreened wastewater can pass through the screen and best separation results are met constantly and reliably. Low-maintenance direct drive The HUBER Drum Screen LIQUID is equipped with a unique, self-adjusting bearing unit. The drum can therefore be mounted stress-free with automatic angle compensation. The bearings are automatically lubricated for maximum availability. Model Variants The HUBER Drum Screen LIQUID is available in different designs and suitable for numerous applications of sol­ids-liquid separation. Depending on the specific application requirements the horizontal drum is covered with a mesh, wedge wire or perforated plate. Drum Screen LIQUID ww HUBER Drum Screen LIQUID with wedge wire drum, wedge wire sizes 0.5 / 1 / 2 / 3 mm. Solids retention with high throughput capacities of up to 10,000 m³/h per machine.
