Picatech Huber AG products

The HUBER Fine Screen ROTAMAT® Ro1 operation is based upon a unique patented system that allows combination of screening, washing, transport, compaction and dewatering in a single unit. Depending on the screen bar spacing (6 or 10 mm) and screen size (screen basket diameter of up to 3000 mm), the throughput can be individually adjusted to specific site requirements. The HUBER Fine Screen ROTAMAT® Ro1 is completely made of stainless steel and acid treated in a pickling bath. These screens are either installed directly into the channels, or are supplied as tank-mounted units, with an inclination of 35°. The wastewater flows into the open end of the inclined screen basket and then through the screen. Floating and suspended materials are retained by the bars of the screen basket. Blinding of the screen surface generates an additional filtering effect so that solids can be retained that are smaller than the bar spacing.

The EscaMax® complements the well-known HUBER program for municipal and industrial wastewater screening, as it is particularly well suited in situations where excellent separation efficiency is required in deep channels with high water levels. The sturdy EscaMax® screen is able to reliably cope with high amounts of gravel and grit. The two-dimensional screening elements prevent especially long fibres from passing through the screen and thus achieve the maximum separation efficiency. Perforated screening elements provide superior separation efficiency in comparison with bar screening elements. It has been determined that two-dimensional perforations are better than one-dimensional bars.

The 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 whilst it also offers a high operational reliability. The motor linkage drive has been developed from the well-proven and patented link system. To the benefit of our customers we intentionally avoided difficult-to-maintain chain drives. With the linkage type we are able to master the occurring bending moments on the lamellas, especially with high water levels.

We developed and supplied our first ROTAMAT® Complete Plant Ro5 during the 1980s. Since then hundreds of consulting engineers and operators have selected and installed our Complete Plants because of their reliable operation and low maintenance. Planning and installation of our ROTAMAT® Complete Plants is not only quick and easy, but also saves considerable construction costs.

The ROTAMAT® Membrane Screen is used for screening of municipal and industrial wastewater and for separation of fibres and hairs. The screen can be installed either directly into a channel or a separate tank. For the new type of membrane bioreactors that have recently been put on the market the efficiency of conventional screens with typical bar spacings and perforations of 3-10 mm is no longer sufficient. The HUBER Membrane Screen is a very fine screen with a low headloss and provides a large screening surface due to its drum-shaped screen basket and 35° installation angle. The screen uses a square mesh that provides, contrary to conventional slot screens, a defined separation size and therefore ensures reliable separation of solids.

A HUBER Fine Screen ROTAMAT® Ro1 is installed in a tank. The septic sludge is fed into the tank and, as it flows through the Fine Screen, all coarse material is retained. A screw conveyor with integrated screenings press removes the screenings from the tank, reduces their volume and weight and drops them into a container or bagging device. The entire treatment takes place in a fully enclosed system; odour nuisance is thus prevented. The screenings are additionally washed which makes them suitable for landfill. The filtrate is blended into the wastewater for further treatment in the WWTP. The efficiency and rugged construction of this type of sludge acceptance plant is able to cope with throughputs up to 100 m³/h and has proved is reliability in every day operation. A compact construction in connection with intelligent technology provides the conditions for continuous operation - day after day, year after year.

Basic and sturdy screen made from stainless steel. Flat material with perforated bottomplate. With stable, frost-proof and corrosion-resistant plastic rollers. Guide and support rails for vertical movement of the basket. The guide rails are curved towards the discharge to ensure a partly automatic discharge of screenings into the customer's skip. The residual screenings are removed manually by means of a hand rake. Whenever the screen basket is in the retracted position, a fall screen automatically shuts off the inlet. Drive with electric chain pull and with block an upper and lower limit.

Continuous deep bed filtration with sand bed heights between 1 and 2 meter fulfils the high requirements on effluent quality. In combination with a physical/chemical treatment stage (precipitation/flocculation) also dissolved material (e.g. orthophosphate) iscarried over into the solid phase and separated in the filter. Colloidal material is agglomerated to filterable material is flocculated to filterable material. Measurements have shown that the CONTIFLOW® significantly reduces the number of germs. In case of increased disinfection requirements, installation of a subsequent UV disinfection unit is possible due to the low concentration of solids in the filtrate.

The HUBER Active Carbon Filter CONTIFLOW® GAK removes micropollutants from the wastewater flow. The system uses granulated active carbon and is installed downstream of the secondary clarifier. An important advantage of the HUBER Active Carbon Filter CONTIFLOW® GAC is that it has no influence on existing process-engineering systems on the sewage treatment plant and can be optimised further by adding a sandfilter or an upstream ozonisation plant. The HUBER Active Carbon Filter CONTIFLOW® GAK is a deep-bed type upflow filter. The system is highly efficient as no shutdowns for backwash cycles are necessary for the active carbon washing process.
