Dewatering RDF/SRF

RDF/SRF is waste used as fuel in incineration plants for energy production or in cement kilns. For optimizing the value of the fuel it can be necessary to dewater it. The RUNI screw compactor is able to dewater RDF/SRF in a continuous process with a low use of energy.

The conditions at RDF facilities are extremely demanding and plants are working 24/7 all year round. In the RDF there are often abrasive elements like sand. Therefore great demands are required of the machine and the RUNI can do it.

Where Does the RDF /SRF Waste Come From?

The RDF/SDF can be generated from reject from paper mills or from MSW (municipally solid waste). Often it is shredded down to around 10 mm in size and can therefore easily be fed to the RUNI.

The RUNI Screw Compactor Solution for RDF /SRF Waste

The RUNI SK370 screw compactor has for many years proved to be a liable and strongly built screw compactor with reinforced screw and constructed to work 24/7 with a capacity of 5-10 tonnes per hour.

The screw compactor can be installed as the last link in the line. The machine can be fed with material via conveyor belt or directly under a rotating drum.

The RUNI achieves up to 75% of dry matter after dewatering RDF/SRF waste.

Case Studies

Oyak Cimento

With a customized RUNI system, Oyak Cimento in Turkey reduced the water content in their RDF from over 50% to below 30%, significantly increasing its calorific value and making operations more efficient and flexible.

Sonoco/Skjern Paper

By compcating and dewatering wet reject, Skjern Paper has significantly reduced both transportation and disposal costs – while creating a more sustainable process where the water is reused in production.
