The Swiss Combi® drum drying process is
universally recognised as a long term secure route as an economic
solution for the treatment of municipal liquid wastes. The treatment
produces a granular product that is suitable for agriculture,
arboriculture and energy production.
The unique closed loop drying system produces a high quality
granular product from both raw and treated sludges. A complete
turnkey operation requiring no additional equipment – this
well established process has flexibility and quality at its core.
