EnviroLine - Enviroscreen - Shaftless Screw Screening
The Enviroscreen series SRS using shaftless screw is particularly adapted to project where effluent is delivered by gravity. The unit insures screening and conveying of waste. However, to match with specific applications or installations, it is possible to add a compacting zone for dewatering the waste (model SRS/P). There is also a built-in tank version, for pump discharge operation (SRS/CP series). The effluent is flowing through the filtration grid where solid waste is stopped and removed under the action of the conveying shaftless screw towards the upper part to be discharged. Up to 1000 m3/h can be processed per unit.

The effluent is processed through the cylindric filtration grid. Due to such design, the effective filtration area is much larger compare to flat screening technology. Therefore, the ratio between size/flow allows to reduce the overall dimensions of the unit. Brushes are fixed onto the shaftless screw in order to keep the filtration zone clean and flow efficient by rotation during operation.
The screw is extended to the conveying zone and then to the compacting zone before solid waste discharge.
The waste is conveyed towards the upper part of the machine towards the discharge zone, the position of which is defined by the length of the conveying zone adapted to the lay-out.
In order to reduce the organic content present in the solid waste, washing ramps can be installed at the screeening and conveying zones.
The screening waste can be either discharged directly into containers or conditionned in continuous closed plastic bagging unit.
