The FSM back pressure device is an optional extra which is installed downstream of a screenings washing press to optimise the dry solid matter content (TS).
The FSM screening washing press is synonymous with hygienic and efficient handling of screenings. Waste disposal is a cost factor at every installation – wet screenings are heavy screenings and increase your costs. The septage in the water must be delivered to the subsequent sewage purification processes.
The FSM screening washing press reduces the weight and volume of your screenings and in addition washes out more than 95% of fecal matter.  

Functional principle:
The FSM back pressure device is optionally built into the discharge pipe of a screenings washing press. The open section of the discharge pipe is varied by means of a shutter which is operated by a hydraulic cylinder.

The TS content can be set to the required value – a TS value of over 50% can be achieved.
To ensure high operating reliability at high TS values, the current consumption of the screenings washing press drive is monitored and a special drive control prevents high wear of the extruding screw. We thus achieve high performance combined with low operating costs. After leaving the back pressure device, the screenings remain in the discharge pipe and drop into a container or onto a conveyor at the end of the pipe.

Further optional extras:

A cutting device, a swivelling unit or a sack packing device can be optionally fitted at the end of the discharge pipe.

Features:
• High reliability through robust construction
• Reduction of waste disposal costs, minimising of volume and weight of screenings.
• Made of stainless steel
• Can be easily retrofitted to an existing installation, because very flexible and adaptable.
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Machine completely hygienically encapsulated
