Sludge treatment : liming before dewatering = Calci-treatment®



Benefits of Calci-treatment® :

Liming sludge after dewatering, through what we call Calci-finishing®, provides:
- Stabilization/Hygienization
- Odors reduction
- Neutralization
- Dry matter increase
- Increase of agronomic value (Ca, Mg)
- Trace metal inerting

But in addition, this process also brings various advantages, such as :
- Reduction of Sludge Volume
- Ease of Use
- Improvement of centrates and filtrates quality
- Reduction of dust emmission



How does it work ?

Calci-treatment is the synergy between a Neutralac® reagent and an adapted polymer to improve the dewatering (evacuate a larger amount of water in the filtrate) and obtain a structured and limed sludge fulfilling the needs of the disposal routes



Easy to implement :

& a viable solution whatever the dewatering equipment


Calci-treatment® additional benefits:

It has been demonstrated that Calci-treatment® can:
- reduce sludge quantities by more than 10 % in the case of belt filter, and around 5% on centrifuge and filter press. This has a direct impact on reducing operating costs associated with sludge re-use and disposal.

- increase the dry solids content of the sludge which gives it a granular structure and improves its pilling behaviour. Thus facilitating storage, transportation and spreading of the sludge.

- stabilize and sanitize sludge using an easy and secure liming equipment. Hence, creating a safe and environmentally friendly sludge treatment solution.

- significantly reduce the total P content of filtrates and centrates
