Why add Neutralac® to sludge treatment?

Main liming sludge performances:

Trace metal solubility decrease

pH influence on trace metal solubility :

Therefore liming allows to capture various metals present in the sludge.

There are numerous interests in liming sludge :

- reducing of the sludge, toward dry matter increase

- stabilization and hygienization of the sludge

- inerting heavy metals present in sludge

- improvement of the sludge characteristics for their disposal or further utilization, such as agriculture recycling, toward: odor reduction, structuring, improvement of their ease of use, and increase of their agronomic value

- improvement of centrates and filtrates quality (N,P)
