The better wastewater is purified, the more sludge is generated. Primary sludge consists of solid materials removed from raw wastewater. Secondary sludge consists of biomass obtained through biological treatment. Tertiary sludge is generated through advanced chemical/physical treatment.
The most important sludge treatment processes include:

1. Pretreatment of water to remove debris and other solid materials
2. Thickening to reduce the volume of sludge by concentrating solid materials
3. Hygienization to deactivate pathogens
4. Dewatering by mechanically removing water
5. Drying by removing water through evaporation
6. Incineration through thermal oxidation of organic solid materials

We offer highly efficient and comprehensive HUBER solutions for sludge treatment, from mechanical pretreatment with screens to reuse of sludge.
