Drum Screen outside-in

Categories:

A device for precise mechanical wastewater treatment in facilities with small and medium capacities. Most commonly used in the food industry for the separation of larger solid particles and fatty contaminants present in industrial wastewater.

Application

RMB TP outside-in drum screens are used in the process of preliminary mechanical treatment of raw wastewater. Their primary function is the effective separation of solid contaminants before the wastewater is directed to subsequent technological stages.

They are particularly well suited for facilities with small and medium capacities, where precise removal of fine solid particles as well as organic and fatty contaminants is required.

Areas of application for ESMIL outside-in Drum Screens:

  • wastewater treatment in the food industry,
  • wastewater treatment in the processing industry,
  • preliminary treatment of municipal wastewater.

Technological advantages of ESMIL Drum Screens

  • Compact design – small dimensions of the unit (while maintaining high throughput) allow installation even in limited technical spaces.
  • The triangular-profile filtering mesh design enables efficient removal of fine contaminants with particle sizes of 0.25 mm and larger.
  • Scraper positioned on the drum surface mechanically removes accumulated solids from the filtering surface, ensuring continuous operation and reducing the risk of clogging.
  • Internal spray nozzle system ensures thorough cleaning of the filtering surface and stable operation even in the presence of fats and petroleum compounds.
  • Automated operation – the unit can work in different modes and can be easily synchronized with other elements of the technological installation.
  • Integrated overflow system – the screen design includes an emergency overflow to prevent overfilling under hydraulic overload conditions.
  • Electrical protection against overloads and voltage surges ensures stable and safe operation.
  • Simple and well-thought-out construction provides easy access to all key components of the screen.

Additional equipment

  • SCP Screw Compacting Press – a device designed for washing and dewatering screenings. It enables significant volume reduction, thereby lowering transportation and disposal costs.
  • Screw Conveyor – used for transporting materials generated during the wastewater treatment process, such as screenings, washed sand and dewatered sludge.

Is it possible to use treated wastewater for washing the filter cloth of the screen?

Yes, that is possible. To clean the screen cloth, technical quality water can be used that does not contain corrosive substances that may clog the valve or nozzles.

Is it possible to equip the Esmil Drum Screen with a press for waste compaction?

Yes, the ESMIL Drum Screen can be supplied complete with a compacting press. Additionally, at the request of the customer, it is possible to make a configuration with a sealed casing for connecting the screen and the compacting press.

Is rough treatment necessary before the Esmil Drum Screen? What size of waste particles can be taken away with it?

Heavy coarse objects settle in the basin of the screen, more buoyant large particles cannot harm the screen, since they approach the drum from the outside and cannot block anything. However, we recommend filtering of the effluent to get rid of the particles larger than ¼ of the diameter of the drum screen inlet pipe.
