Our HUBER Brands

The HUBER® brand stands for innovative and high-quality machines, plants and products made of stainless steel, which are used for water treatment, water supply, wastewater treatment and sludge treatment.

The HUBER® brand is complemented by the HUBER Technology® word and figurative mark, which stands for the visual recognition value of the company and its products. With over 55,000 plants installed worldwide, HUBER focuses on sustainability and efficiency to solve global water problems and promote a clean environment.

In 1983 HUBER introduced a new type of fine screen for mechanical wastewater treatment to the German market for the first time. The screen, made entirely of stainless steel, consists of a cylindrical screen basket which is cleaned by a rotating screen rake. The feature of the ‘rotating’ mode of operation was the inspiration for the brand name ROTAMAT®, under which this screen was marketed and very quickly gained acceptance both in the German and soon in international markets. This proven screen can still be found in the HUBER product programme today.

Based on its success, further screens and screening plants as well as complementary products were soon developed in addition to the Ro1. The following ROTAMAT^® screens are currently in the HUBER product programme:

• HUBER Fine Screen ROTAMAT^® Ro1
• HUBER Rotary Drum Fine Screen ROTAMAT^® Ro2 / RPPS / STAR
• HUBER Micro Strainer ROTAMAT^® Ro9

These screens are also key components of the multifunctional ROTAMAT® Complete Plant product family. These plants have been providing comprehensive and at the same time compactly combined mechanical wastewater treatment since the mid-1980s:

• HUBER Complete Plant ROTAMAT® Ro5
• HUBER Complete Plant Hydro Duct ROTAMAT® Ro5 HD
• HUBER Coanda Complete Plant ROTAMAT® Ro5 C

Other ROTAMAT® screening systems for pumping stations, manholes and spillway structures are based on a rotating operating principle:

• HUBER Pumping Stations Screen ROTAMAT® RoK4
• HUBER Storm Screen ROTAMAT® RoK1
• HUBER Storm Screen ROTAMAT® RoK2

The company Hydropress Wallander & Co. AB, based in Lindome, Sweden, invented a new concept for a fine screen in the early 1980s and applied for a patent. The screen system quickly became known worldwide under the brand name STEP SCREEN®. The outstanding feature was the self-cleaning system based on the counter-current principle without any additional aids, ensuring reliable separation and transport of the screenings. The special design of the screen with step-like lamellas led to the brand name STEP SCREEN®.

In 1998 HUBER took over Hydropress, including all patent and trademark rights, and added the STEP SCREEN^® to its range of screening plants. HUBER continued to develop the screen and has been marketing the HUBER Fine Screen STEP SCREEN^® SSF and the HUBER Fine Screen STEP SCREEN^® SSV since the end of the 1990s.

The brand name RakeMax® was registered by HUBER in 2003 as the name for a rotating rake screen. The bar rack is cleaned by rakes which are attached to a revolving chain. The principle of the rake screen has been known for a long time and was rediscovered by HUBER in the early 2000s and perfected in the RakeMax® machine. 

The high level of acceptance and worldwide customer satisfaction with the HUBER Multi-Rake Bar Screen RakeMax®, which is one of the most frequently used screens in the world, motivated HUBER to develop further screens with the same principle for slightly more sophisticated applications: 

• The HUBER Multi-Rake Bar Screen RakeMax® HF consists of a flat and therefore hydraulically advantageous bottom section and a steep conveying section.
• The innovative HUBER RakeMax® CF was invented by HUBER in 2016 and consists of a U-shaped fixed bar rack arranged parallel to the flow direction of the wastewater. The wastewater streams into the open face of the screen and then out through both the left and right bar rack.

The brand name TrashMax® was registered in 2010 and gives its name to a coarse screen developed by HUBER. The HUBER Coarse Screen TrashMax® is a chain screen with rakes that is able to safely remove particularly bulky and large solids from the wastewater flow and thus reliably protect downstream equipment.

The HUBER Belt Screen EscaMax® uses a perforated plate as a screening element which is attached to a revolving chain. The screenings are separated on the perforated plate and transported together with it upwards out of the channel, where the screen elements are then cleaned at the deflection point by an internal spray nozzle bar. This type of screen is often referred to as an ’escalator screen’. Inspired by this, the EscaMax® brand was developed and registered by HUBER in 2003. 

The proven basic principle of the EscaMax^® was adapted by HUBER for the development of other belt screens – especially for river and sea water intake applications: 

• HUBER Band Screen CenterMax®: In 2016, HUBER developed a belt screen for both municipal wastewater treatment and water intake applications. The wastewater streams into the open face of the screen and then out through the left and right bar rack. The brand name CenterMax® was registered by HUBER in 2016. ‘Centre’ stands for the water flowing inside into the centre of the screen.
• HUBER Band Screen DualMax®: In 2022, HUBER developed another belt screen especially for use in water intake applications and registered the brand name DualMax® for it. This screen is characterised by an opposite flow direction compared to the CenterMax®. The water flows into the screen through the left and right screen elements and out again via the open front. This special feature of the ‘dual flow’ into the machine from both sides through the screen elements led to the name DualMax®.
• HUBER Band Screen DiscMax®: The brand name DiscMax® was registered in 2021 and stands for a fine screening machine that is primarily used for water intake applications. The screen is a direct-flow belt screen with crescent-shaped screen elements that resemble a disc. 

In 2003, HUBER developed a rotating fine screen drum, which is mainly used for industrial wastewater and process water treatment. The brand name RoMesh® was registered for this purpose. The HUBER Drum Screen RoMesh® can be fitted with perforated plate or mesh as screening media, with the latter forming part of the brand name.

In 2005, HUBER launched a micro screen for the reliable separation of very fine solids under the brand name RoDisc®. The HUBER Disc Filter RoDisc® consists of up to 35 vertical discs connected by a horizontal shaft. During operation, up to 65 % of the filter surface is submerged. The solids are removed from the filter surfaces by the slow rotation of the filter discs combined with spray nozzle bars.

The RotaFilt® trademark was registered by HUBER back in 1994. At that time, the brand stood for a rotating filter drum that used a pile cloth as the filter media. In 2019, HUBER then began developing a disc filter, which has been marketed worldwide under the name HUBER Pile Cloth Media Filter RotaFilt®. As a pile cloth filter, it is used for the reliable separation of the finest suspended substances, including microplastics, and is typically used in the 3rd and 4th treatment stages of wastewater treatment plants.

As early as 2003 HUBER developed a screening drum specially designed for screening faecal sludge. For more than 20 years this machine was marketed under the name RoFAS until HUBER decided to change the name to HUBER Sludge Acceptance Plant RotaShield®. The corresponding trademark RotaShield® was registered in 2024.

The brand name CONTIFLOW® was registered by HUBER in 2000 as a designation for a continuously operated deep-bed type upflow filter. The filter provides filter bed cleaning without interrupting the filtration process and can be designed as a stainless steel tank or in concrete construction. Its modular design ensures the optimal treatment of any throughput. In addition to the HUBER Sandfilter CONTIFLOW^®, which uses sand as the filter medium, there is also the HUBER Activated Carbon Filter CONTIFLOW® GAK, which is used for the elimination of trace substances in the fourth treatment stage.

The brand name WAP® was registered by HUBER in 2015 and stands for a machine whose function can be described as Wash And Press. It now stands for a whole family of machines developed by HUBER for the treatment of screenings. HUBER has been involved with wash presses for screenings treatment since the 1990s. From the first machines, which were marketed under the name HUBER Screenings Wash Press ROTAMAT® Ro4, HUBER has developed the current series of WAP® machines for various applications over the years:

• HUBER Wash Press WAP® for washout and dewatering of screenings
• HUBER Wash Press WAP® SL for particularly intensive washout and dewatering
• HUBER Wash Press WAP® SL HP for particularly intensive washout and best possible dewatering 

HUBER has been involved with grit traps for decades and has various types of round and long grit traps in its programme. The desire of some customers for a significantly higher grit separation capacity in relation to the space requirement led to the development of a unique lamella grit trap, for which HUBER registered the name GritWolf® as a trademark in 2015. The idea for the name came from employees of the HUBER subsidiary in the USA. However, some HUBER employees do not suspect an animal behind the name ‘Wolf’, but an allusion to the name of the inventor: Wolfgang Branner (HUBER Product Manager Grit Separation).

In 2017, HUBER developed the CarbonWin® process, which makes it possible to convert a wastewater treatment plant from aerobic to anaerobic sludge stabilisation despite limited space. The core of the process is the mechanical screening of the wastewater with the HUBER Drum Screen LIQUID, which performs the task of primary sludge separation. The primary sludge is then converted together with the surplus sludge in the digester into methane, which can be used to generate electricity in a combined heat and power plant.

This process conversion results in an enormous increase in the energy efficiency of the entire wastewater treatment plant. HUBER has registered the name CarbonWin® as a trademark for this process in reference to the fact that carbon is ultimately extracted from the wastewater to generate electricity.

The STRAINPRESS® machine and the associated brand name came to HUBER SE in 1998 when HUBER took over the company PICATECH AG based in Lucerne/Switzerland. PICATECH AG sold this machine very successfully both in Switzerland and internationally for municipal and industrial applications in the field of sludge screening.

The HUBER Sludge Cleaner STRAINPRESS® is a horizontal cylindrical screen developed for the continuous separation and dewatering of foreign matter. It is used for screening liquid sludge or for filtering pressurised process water. Backwashing of the screen is not required, so no wash water is needed. The brand name STRAINPRESS® is derived from the function of the machine: STRAIN as a synonym for screening and PRESS for pressing the screenings to dewater them.

At the end of the 1980s, HUBER was already involved in the dewatering of sewage sludge and developed the first screw presses for this purpose. At that time they were marketed under the name HUBER Screw Press ROTAMAT® RoS 3 and later also under the name RoS 3Q. After many years of successful further development and optimisation, HUBER finally registered the brand name Q-PRESS® for a new generation of screw presses in 2015. Since then, the HUBER Screw Press Q-PRESS® has proven itself in thousands of installations worldwide, making it one of HUBER's best-selling machines.

The brand name SOLSTICE® was registered for the HUBER Sludge Turner in 2015. This product for thermal sludge treatment was introduced to the market by HUBER as early as 2003 and since then numerous solar sludge drying plants have been built using the HUBER Sludge Turner SOLSTICE®. One of the largest solar sludge drying plants in the world was realised in Egypt (Bahr El-Baqar) ) with 128 of these sludge turners.

In 2024, HUBER registered the trademark FloorRunner® for a newly developed sludge turner. This is now the fifth further development of the well-known HUBER Sludge Turner. The special feature of the FloorRunner® compared to the SOLSTICE® is the elimination of the lateral concrete walls. The HUBER Sludge Turner FloorRunner® runs directly on the ground. This further development reduces the costs of the entire plant.

In addition to solar sludge drying with the sludge turners described above and the HUBER Belt Dryer BT, HUBER added a disc dryer to its product range in 2019 in cooperation with the company Oestergaard/Norway. This contact dryer for the partial drying of sewage sludge is marketed under the brand name RotaDry®. The HUBER Disc Dryer RotaDry® enables the subsequent utilisation of sewage sludge in fluidised bed incineration plants.

In 2024, HUBER started to develop a cold air dryer in order to be able to offer a fourth type of drying process in its portfolio. Sludge is dried here at just 40° C, with the drying air being circulated. The heat supply is ensured by a heat pump system (Heat Pump System). This is also where the name HUBER Cold Air Dryer HPS® comes from, which was registered as a trademark in 2024.
