Why add Neutralac^® to sludge treatment?

Main liming sludge performances:

Sludge Dewatering is optimized with lime-based reagents and flocculants.

For example, in post liming, a 20% DM sludge which is limed with a 30% CaO rate will have a resulting dry matter of 26%.

In the case of Calci-treatment (pre-liming) the resulting dry matter would be even higher due to the increased dewatering efficiency.

- 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)
