Biosolids can be applied as fertilizer to improve and maintain productive soils and stimulate plant growth. They also are used to fertilize gardens and parks and reclaim mining sites. Biosolids are carefully monitored and must be used in accordance with regulatory requirements.

In many cases, biosolids are dewatered before they are beneficially reused. Biosolids are often just 3-5 percent solids, so removal of the water from the material is essential to reducing weight and the cost of further treatment or disposal or reuse.

A variety of technologies are employed to dewater biosolids—including filter presses, belt presses, and other devices.

Siemens offers a complete range of biosolids dewatering systems, for all sizes of treatment plants, and suitable for all forms of reuse applications—including land application, composting, and incineration.
