HUBER Sludge Acceptance Plant ROTAMAT® Ro3
Well-proven, efficient and rugged Septage Receiving Station
- with integrated screenings press
- with integrated screenings washing
- no odour annoyance outside
This septage receiving station is used for mechanical treatment of septic sludge.
A HUBER Fine Screen ROTAMAT® Ro1 or HUBER Micro Strainer ROTAMAT® Ro9 is installed in a tank. The septic sludge is fed into the tank and, as it flows through the Fine Screen or Micro Strainer, 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.
If an outstanding separation efficiency is required, every version of Septage Receiving Station can be alternatively equipped with the well-proven ROTAMAT® Rotary Drum Fine Screen Ro2.
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.
There are two versions of the septage receiving station available: with a fine screen or micro strainer:
HUBER Sludge Acceptance Plant ROTAMAT® Ro3.1 - Sludge Screen with Fine Screen
The robust and efficient Ro3.1 version has become the most popular system of its kind. Its superior design and engineering guarantee most dependable operation – day after day, year after year.
The main component of this Sludge Acceptance Plant is the reliable HUBER Fine Screen ROTAMAT® Ro1. It excels with its high capacity, good separation efficiency and low head loss. Another exceptional feature is its integrated screenings press with all its benefits.
The ROTAMAT® Fine Screen is extremely sturdy, able to deal with rocks and grit, and is entirely made of stainless steel. It is fully self-cleaning as its rake tines fully engage with the basket.
HUBER Sludge Acceptance Plant ROTAMAT® Ro3.2 - Sludge Screen with Micro Strainer
This is an efficient and low-cost alternative to our Ro3.1. It can be used for low flow and load applications.
In this Ro3 version a HUBER Micro Strainer ROTAMAT® Ro9 is installed in a container. The screen basket is cleaned by the stainless steel screw. Additional cleaning is achieved by wear-resistant brushes fitted to the screw flights. As the screenings are conveyed upwards within the closed rising pipe they are compacted in the integrated screenings press prior to being discharged.
Advantages of the HUBER 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 lossDue 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.
