advanced dewatering of sludge by pre-liming before centrifugation – Dehydris™ Lime
The Dehydris™ Lime, pre-liming for sludge with centrifugation, is suited to the dewatering of all type of sludge, fresh or digested from urban wastewater treatment and to any size plant.
Developed to take advantage of the different properties of lime (sanitization, reduction of odors). DeshydrisTM Lime is used at the end of the sludge treatment process. The biosolids, due to their granular structure, can then be used directly as agricultural recovery with an optimized storage.
key figures
- 100% homogenous sludge-time mixture
- Important gain in dryness, up to 50% compared to traditional centrifugation
