Sludge & Biosolids

Your sludge, our resource

At Krüger, we see sludge not as a waste but as a potentially valuable resource.

We apply our global technological leadership to help municipal clients extract valuable biosolids and produce agriculturally-beneficial byproducts. By converting sludge into energy, we help offset wastewater treatment plant operation costs.

Our designs minimize sludge generation in the initial phases of water treatment. For sludge that remains after recovery, we minimize weight and volume and remove harmful substances prior to disposal. Our sustainable treatment solutions meet rigorous health and environmental standards.

Key technologies for sludge treatment

Solia™ greenhouse solar sludge dryer

Technologies we apply to treat and leverage value from sludge include:

  • Pyrofluid™, sludge incineration, energy recovery and ash recycling
  • Athos™, hydrothermal oxidation for sludge reduction

The expertise of a global leader

Exelys™ thermal hydrolysis solution

In water and wastewater treatment

Krüger is a leading expert in custom-designing and constructing sludge treatment solutions for municipal water and wastewater treatment plants.

Our innovative Exelys™ technology represents the next generation of biosolids thermal hydrolysis. By concentrating the matter to be treated, the volume to be heated is reduced yielding:

  • 20-40% more biogas than conventional digestion
  • Up to 50% more capacity for existing digesters
