Technical details

Operating Principle

Based on combined solar drying and bio-drying, SOLIA™ Mix dries and stores sludge in a horticultural greenhouse under continuous ventilation with dry air from the outside.

Dewatered sludge and drying sludge are mixed and shaped into windrows by the SOLIAMIX™ windrow turner.

Windrow operation and regular addition of fresh sludge maximize bio-drying, and promote easy storage of sludge on a 6 months to 1 year cycle in the greenhouse. Solar radiation, along with bio-drying, promotes a temperature rise within the windrows, thus improving water evaporation.
