MEVA Monoscreen
The MevaScreen RSM is a patented self-cleaning fine screen for water purification with very high demands on the degree of separation. It has been designed to improve the separation of the screen bottom step – a weakness in other screens. The MevaScreen RSM provides sustained slot width over the entire surface of the screen. The screen can be operated with an almost complete screenings mat over the entire screen surface, and is the only screen on the market ensuring a slot width down to 0.5 millimetres over the entire screen surface, even during operation.
Meta MonoScreen Information
The MevaScreen RSM’s unique patented design provides many benefits, especially under water and above all at the bottom step.
The MevaScreen RSM has a pattern of movement in which the specified slot width is maintained throughout the work cycle. The progressive movement means that only a small part of the screenings mat is transported up during each screen cycle.
This minimises the ‘rush’ of water that might otherwise occur through the screen after a normal screen cycle. The risk of blockage due to sand, stone and similar materials is eliminated by the moving parts never opening a larger slot between the rods than the specified slot width.
You can run the MevaScreen RSM with very short pulses and it does not need to perform a full work cycle to its home position. Thanks to this approach the separation enhancing screenings mat can be made fully covering, leading to an unprecedented separation of up to 50% higher than in other designs.

Area of use
MEVA MONOSCREEN is a self-cleaning fine screen for water treatment with a very high degree of separation of solids from water. Extensive development of this product has led to a high separation at the bottom of the screen, a weak spot in other fine screens on the market when screening slot width is less than 6mm for wash water requirements. The MEVA MONOSCREEN guarantees the slot width along the entire screening surface and can be operated whilst fully covered by the screening mat. Slot widths 0,5 - 6mm. A 1mm MEVA Monoscreen has similar separation to a 300 micron drum screen, without the accompanying clogging problems or washwater requirements.
Functionality
The unique patented design gives MEVA Monoscreen several advantages, especially below the water surface and at the bottom of the screen. The screen’s motion operates within the predetermined slot width for the duration of the working cycle. Due to the progressive movement only a small part of the screenings mat is transported upward during each cycle. This minimises the “rush” of water through the screen that can occur after a traditional screening cycle. The blockage risk is eliminated by the design as the moving parts never open wider than the actual slot width. It is for this reason that the screenings mat can cover the screen fully during operation. This ensures a very high degree of separation (up to 50% more than other designs). Screenings capture ratio tests results at 83%, which equals that of punched hole screens, however without the need for wash water or brushes. MEVA Monoscreen can uniquely ensure slot widths as little as 0.5mm for the entire screening surface.
Automatic Control
MEVA MOTOSCREEN works intermittently, allowing operation to be adjusted to the incoming flow. A level sensor is installed in the channel in front of the screen. The screen starts when a pre-set water level is reached and operates until the water level is below the pre-set value. The cycle is repeated when the level is reached again
