Composting system technologies from Siemens Water Technologies.

From high solids mineral processing applications to conventional industrial waste sludges, to lime softening residuals, we have a filter press to meet your dewatering needs.

We offer alum sludge thickening, dissolved air flotation (DAF) thickening, gravity thickening, lime sludge thickening, mechanical and rotary drum thickening.

Thermal drying is a process for the reduction of the volume of wet solid products, by removing the moisture and achieving dry solids concentration over 90%.

The need for solids reduction is becoming more evident as the volume of generated wastewater solids is growing and many local governments are choosing to dispose of the nutrient-rich solids through burial in landfills or incineration.
