Why add Neutralac^® to sludge treatment?

Main liming sludge performances:

Structuring & ease of use

Lime is essential for sludge conditioning:

- first, lime-based reagents largely contribute to the flocculation process for the dewatering step.
- thanks to lime, sludge get a better structure, a better workability and better storage properties.

Dewatered sludge - storage step - Non-limed sludge - limed 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)
