These are food industry wastewaters (fertirrigation) and liquid sludge or sludge from lagoon cleaning.

Liquid and thickened sludge
Containing between 2 to 7% of dry matter, these originate mainly from small treatment plants (urban or industrial).

Lagoon cleaning sludge
This is sludge from the cleaning of small communities lagooning plants.

Cake
Dewatered mechanically by belt filter or by centrifuge. Dry matter content is around 15-25% (urban or industrial origin).

Limed sludge
Cake (dry matter 25%) or solid (>30% dry matter), stabilized and potentially hygienized. These sludges are conditioned with quick lime (urban or industrial origin).

Solid sludge
After a thermal process or liming followed by dewatering by filter press, the sludge piles with a dry matter content of around 35 - 50% (urban or industrial origin).

Paper mill sludge : (industrial origin).

Gypsum : (industrial origin).

Drinking water treatment sludge : (urban origin).

Decarbonation treatment sludge : (industrial origin).

Lagoon cleaning sludge
This results from cleaning of lagooning ponds for small communities.

The dried sludge is sludge dewatered by thermal drying pushed up to 90% dry matter.
They come in powdered or granulated form. (Urban or industrial).
