The Freeze Dry Unit is applicable in a variety of different markets. The unique process of Freeze Dry Unit uses to reach a high dry solid content makes it very well rounded in its areas of use, as well as it enables new ways to dispose of the residues, sludge, spent grains or slurries in ways that was not before possible. Freeze Dry Unit keeps the energy use low as well as transports can be reduced. This is good for both the economy and the environment! The Freeze Dry Unit has been pilot tested at a municipal wastewater treatment plant in Sweden, but also in smaller scale with sludge from biogas production, cellulose from paper industry and sludge from the food and beverage industry as well as algae. The process the Freeze Dry Unit uses enables us to dry sludge with radioactive content for example sludge from dredging.
Residues from fish farms often comes in the form of sludge. These must be taken care of resue and to recirculate the water.
Sludge from biogas production differs from that of municipal wastewater sludge as sludge from biogas can contain crops, manure, residues from farms or slaughterhouses.
In the food industry a lot of the residues from the processes are in the form of sludge and contain valueable economic values, but also the possibility to reuse or create new products. Today there is challenge to effectively make use of these.
In cellulose industry Freeze Dry Unit has several areas of use. The machine can be used to treat different fractions of sludge that results from the paper pulp process and for dewatering and drying of residues.
The nuclear industry produces a radioactive sludge. In the ion exhange process a radioactive sludge is recieved as nuclear particles are trapped inside and forms a sludge like waste that must be taken care of.
Today a lot of the sludge from municipal wastewater treatment plants is dewatered to a dry solid content of 20-30 %. This results in high costs and other problems.
