Application
RP back-raked screens are used in the process of preliminary mechanical wastewater treatment. Their primary function is the effective capture of solid contaminants before the wastewater is directed to subsequent treatment stages.
The use of screens helps protect downstream equipment from overload, mechanical damage and blockages, which translates into greater efficiency and safety of the entire treatment process.
Areas of application for ESMIL Back-Raked Screens:
- wastewater treatment plants,
- wastewater pumping stations,
- water intakes,
- drainage pumping stations.
Design range
Height up to 30 m, width up to 4 m – depending on project requirements.
Technological advantages of ESMIL Back-Raked Screens
- The reverse rake arrangement enables effective capture and removal of materials such as rags, tissues and other textile waste, eliminating the risk of clogging.
- The rake mechanism, located behind the screening surface, comes into contact only with pre-treated wastewater, which reduces fouling and facilitates maintenance.
- The bars installed along the entire length of the screen – from the channel bottom to the discharge point – improve the efficiency of cleaning the filter surface.
- The round cross-section of the bars ensures low hydraulic resistance, resulting in high throughput capacity.
- The applied drive mechanism and well-designed screen construction allow quick servicing without dismantling the device.
- Stainless steel AISI 304 construction provides high resistance to aggressive wastewater environments.
- The absence of rotating elements in the submerged zone reduces the risk of failure and simplifies operation.
- Electrical protection against overloads and voltage surges ensures stable and safe operation.
- No components require constant operator supervision.
- The automated control system enables flexible adjustment of the screen’s operating mode to wastewater levels in the channel or to a programmed schedule.
Mini Back-Raked Screen RMKE
We also offer Mini RMKE Back-Raked Screens designed for installation in tanks up to 1 m deep.
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.
