[...]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,[...]

[...]Mechanical Preliminary Treatment Removal of foreign matter from raw wastewater and sludge Good mechanical pre-treatment protects the subsequent process stages from clogging, blockages, deposits and abrasion. Good mechanical pre-treatment protects the subsequent process stages from clogging, blockages, deposits and abrasion. Solids Separation with Screens and Fine Screens The separation of solids from wastewater with screens is the first step in municipal and industrial wastewater treatment. HUBER has developed a wide range of different screens, fine and ultra-fine screening plants which are [...]

[...]Machines for Screenings Treatment Optimal screenings treatment systems for any application Wash Presses Screenings Compactor Screenings treatment with high dewatering efficiency and maximum washout degree The first step in wastewater treatment is normally the removal of solids from the wastewater flow by means of screens. The removed screenings contain household waste, faecal matter, toilet paper and mineral solids. The screenings volume depends, not only on the separation size of the screen, but also on the type of sewer system. The solids content of municipal screenings varies between 10 % [...]

[...]Grit Traps and Classifiers The best solution for any grit separation application Grit Trap and Classifier Product Groups Longitudinal Grit Trap Lamella Grit Trap Circular Grit Traps Complete Plants Grit Classifier For reasons of operating reliability of wastewater treatment plants it is necessary to separate grit, gravel and other mineral materials transported with the wastewater (an average of 60 l from 1000 m³ of wastewater according to DWA Work Sheet M369) from the digestable organic material. Good grit separation prevents operational problems, such as grit sedimentation in aeration tanks and[...]

The volume reduction is achieved by[...]

[...]Machines for Sludge Dewatering Reliable and efficient methods of sludge disposal by means of screw presses and belt filter presses HUBER Screw Press Q-PRESS® Machines for Sludge Dewatering HUBER Screw Press S-PRESS Machines for Sludge Dewatering HUBER Bogenpress B-PRESS Machines for Sludge Dewatering However you plan to dewater your sludge - HUBER has the suitable solution! Sludge produced in municipal and industrial wastewater treatment plants requires dewatering prior to further treatment or utilisation. In view of increasing sludge disposal costs it has become necessary to concentrate [...]

[...]Plants for Thermal Sludge Treatment Sewage Sludge Drying and Mono-Incineration Sludge Turner for Solar Drying Cold Air Dryer Belt Dryer Disc Dryer The existing and future challenge in sewage sludge treatment is to process the dewatered sewage sludge with further process steps to such an extent that safe disposal or even economic use is possible. With our machines and plants, we provide customised solutions. Reducing the water content of the sewage sludge by drying reduces the resulting disposal costs considerably. Sludge Drying is energy intensive. The energy demand of available drying systems[...]

[...]Retention of filterable solids from the secondary clarifier effluent Reduction of phosphorus by upstream precipitation Preliminary filtration in drinking water recovery from surface waters and in UV disinfection applications High hydraulic loads, insufficient tank depth and poor settling behaviour of the activated sludge are the most common causes for the poor performance of secondary clarifiers. Frequently, secondary clarifiers are even unable to reliably ensure the solids retention required. Overflow of flocks increases COD, BOD and phosphorus loads in the effluent and receiving watercourse[...]

[...]Removal of fibres and hair Service water and wash water treatment Defined separation size COD and BOD removal in river or sea outfall applications Protection of membrane filtration plants Separation of hair, fibres and fine suspended material from municipal and industrial wastewaters is in many applications essential for trouble-free and low-maintenance operation of subsequent treatment stages. Fine mesh screens are required to remove such materials. Wastewater treatment at source is necessary for many industrial installations to meet the requirements for wastewater discharge into sewer systems.[...]

[...]For high separation efficiencies For any flow rate Easy and reliable screenings transport The HUBER STEP SCREEN® System is widely accepted and successful due to its function and easy-to-follow operation principle as well as the simple cleaning method without any aids (self-cleaning effect according to the counter-current principle). It is furthermore easy to maintain and able to handle extremely big screenings volumes while it offers also a high operational reliability. Design and Function The variable installation angle ensures optimal adjustment to individual hydraulic conditions, such as limited[...]
