ROTAMAT® Sludge Screen Ro 3
- with integrated screenings press
- with integrated screenings washing
- no odour annoyance outside
- well-proven, efficient and rugged construction
A ROTAMAT® Fine Screen / Microstrainer is mounted in a container. While the sludge flows into the container and through the fine screen/microstrainer, all solids are removed. An integrated screenings press transports the screenings out of the container, dewaters them, reduces them in volume and finally drops them into a container. The whole cleaning process takes place in a closed system avoiding odour anno 2000 yance outside.
In addition, the screenings are washed and the press water flows back into the channel. As a result the screenings are clean and can be taken for landfilling. The press water with a high BOD load flows back into the wastewater and into the treatment plant for a proper treatment.
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. It is the best selling machine of its type in Germany. A compact construction in connection with intelligent technology provides the conditions for continuous operation - day after day, year after year.
The ROTAMAT® Sludge Screen Ro 3 is available in two variations:
ROTAMAT® Sludge Screen with Fine Screen Ro 3.1
Heart of this sludge acceptance plant is the ROTAMATs fine screen with its high removal efficiency and low head loss. A main advantage is the integrated screenings press. The ROTAMAT® fine screen with its rugged construction is resistant against stones and grit, is completely in stainless steel and it is cleaning itself by tines passing through the bars of the screen.
ROTAMAT® Sludge Screen with Micro Strainer Ro 3.2
This plant type using a Micro Strainer instead of a Fine Screen is an efficient and favourably-priced alternative to Ro 3.1 at a generally lower load.

The advantages of the ROTAMAT® Sludge Acceptance Plants
- high separation capacity
Due to the diversion in the basket the fibrous materials and the bar-shaped particles are considerably better retained than the particles flowing straightly to the rack screen.
- low head loss
Due to the drum shape and the 35° installation considerably more screening area is available for the cleaning than for instance with screening systems installed vertical or inclined. The result: low head loss - maximum throughput
- completely made of stainless steel
The machine is completely made of stainless steel and acid-treated in a pickling bath which eliminates labour-intensive maintenance work otherwise caused by corrosion.
- automatic cleaning
By means of the circulating screening rake the complete screening area is totally cleaned, i.e. even at high pollution load the automatic cleaning ensures a constantly free screening area. Additionally, there is the guarantee that the screenings remain constantly inside the basket (mostly in front of the screening area), thus ensuring that the screenings are not taken out of the waste water and are not transported into the already cleaned waste water behind the screen during the cleaning process.
- several functions in one unit
The machine combines several functions in one system, i.e. screenings removal, transport, dewatering and compaction are combined in one plant, thus saving space. By means of an optional bagging unit the whole plant is virtually smell-tight.
- outdoor installation
With a strip heater and additional insulation the ROTAMAT® Screen can also be used for frost-proof outdoor installation.
- additional equipment
The ROTAMAT® plants are designed in a way that additional modifications on the plant can be carried out afterwards, i.e. the machine can be re-built acc. to future requirements. Heating as well as integrated washing can be installed later on, the bar spacing can also be reduced later.
- minimum maintenance
The plant has no lubrication point, maintenance is reduced to routine control and inspection.
