The drainage characteristics of a municipal sludge depend largely on its composition, with the maximum dry substance (DS) achievable through mechanical methods determined primarily by the content of extra-cellular polymer substances (EPS).  

Efficiency of a dewatering system is characterised by its capacity to remove free water after sludge conditioning.  

Bucher HPS technology’s unique dynamic dewatering principle can remove almost all free water and sometimes even part-bound water. This technology offers the best dewatering performances for most usual conditionings.  

It’s ideal because dewatering efficiency is one of the main ways to achieve sustainable and cost-effective wastewater treatment plant operation.
