Application
KR catenary 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 Catenary Screens:
- first stage of wastewater treatment,
- wastewater pumping stations,
- open inlet channels,
- water intakes.
Design range
Height up to 30 m, width up to 4 m – depending on project requirements.
Technological advantages of ESMIL Catenary Screens
- Special “support chain” design ensures continuous and safe operation even with the inflow of large solids – minimising the risk of jamming and breakdowns.
- Reinforced screen body, engineered with a high safety margin, enables stable operation under high hydraulic loads.
- Simple and well-thought-out design provides easy access to all key components, significantly simplifying technical inspection and maintenance.
- In the submerged part, only corrosion-resistant components are used. In addition, the screen has no bottom chain wheel or bearings that could be damaged by water contact.
- The unit does not require constant technical supervision – operation demands minimal operator involvement.
- Electrical protection against overloads and voltage surges ensures stable and safe operation.
- Automated control system allows flexible adjustment of the screen’s operating mode to the wastewater level in the channel or programming of a time-based schedule.
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.
