In front of the tremendous volumes of sludge generated daily by the wastewater treatment plants, and the lack of sludge evacuation routes, the requirement for further sludge volume reduction after mechanical dewatering systems (centrifuges, belt filter presses, chamber filter presses, screw presses….) becomes a necessary step for sludge volume reduction.
As a sludge treatment specialist EMO can offer a range of low temperature dryer.
- Dryness of dried sludge : 80 to 90%
- Very low temperature technology : 40°C-60°C
- No smells
- No contaminated air
- Very high quality of condensate
- Allowing heat recovery, possibility to use recycled energy
The technology of drying by low temperature costs approximately 50 to 70% less than the traditional thermics system of drying. The sludge dryers are more compact, they are more powerful in a minimum of space. One economic line of dryers with standard drying capacity of evaporation being able to go from 2.5 to 1500 kgs per hour whcih can be easily integrable with an installation of existing plate filter press with less costs of handling. This system respects the structure of sludge and offers an optimal efficiency in case of biological process.
