Recovery and reuse of materials is crucial to maintaining a good and healthy environment for future generations. Through the Cellvation® process, cellulose is recovered from sewage water, transforming waste into a resource.

GRIT REMOVAL

The easily settable solids like sand and grit are removed.

Cellulose

Washer

CELLULOSE WASHER

The water that flows from the grit removal passes through a cellulose washer, which takes out the hair and other organic contaminants.

SALSNES FILTER

After the cellulose washer, the sewage water flows through to the Salsnes Filter, which is a rotating belt filter. The filter works by rotating a filter cloth, creating an endless filter. The sewage water is fed into the machine on top of the filter cloth and then flows through it. The particles in the sewage water form a precoat on top of the filter cloth creating an even smaller pore size. The sievings from the Salsnes Filter are partially dewatered on the filter cloth, before being blown off by an airknife. A screw transports the sievings to the CellPress.

CellPress

CELLPRESS

The sievings filtered out of the sewage water by the Salsnes Filter installation are dewatered by the CellPress.

HYGIENISATION

The sievings are hygienised to reach the EPA class A rating, ensuring that the product produced is clean and safe to use.

POLISHER

When the product is dried, the larger chunks of cellulose are broken down to smaller parts. From there, the cellulose is turned into fluffy cellulose or compacted into pellets, depending on customer demand.
