Biosolids/Bioenergy for Municipalities

Services & Solutions

Veolia's biosolids treatment technologies focus on performance enhancement, renewable energy, beneficial reuse, and removal of PFAS compounds.

We are committed to providing innovative solutions with proven value-added performance, offering a comprehensive solution for every part of the biosolids process in order to be flexible to individual needs or to outfit the entire process.


Our technologies transform vital resources into clean water, clean energy, and valuable end products, thereby empowering utility owners to develop their own regional circular economies.

Reduction in waste to be disposed

Recovery of valuable byproducts including:

  • Biosolids as alternate for fertilizer
  • Nutrients (sulfur, phosphorus)
  • Energy (biogas, electricity, heat)
  • Water (for reuse)

New revenue stream for facility from:

  • Accepting waste from Municipalility
  • Stabilized biosolids as alternate for fertilizer
  • Nutrients recovered
  • Renewable bioenergy generated



Veolia has adopted the risk-based approach to the selection, development and operation of water treatment assets deployed for PFAS contamination removal. We have applied considerable resources to develop a risk management framework that drives the selection and management practices of our treatment processes.



Veolia Water Technologies recovers and recycles your biomass and biowaste in order to extract the most added value from it. 



We offer safe and environmentally friendly biosolid solutions that focus on performance enhancement, renewable energy, beneficial reuse, and optimization.



Recovering phosphorus contained in wastewater leads to a reduction in the production of sludge and the production of sludge with a reduced phosphorus content.


BioCon™ dryer is a dual-belt convective air dryer designed to be one of the safest on the market. Low operating temperatures allow the process to utilize a variety of waste heat sources, such as the easily added BioCon Energy Recovery System (ERS), or BEES BioCon Energy Exchange System.

BioCon™ ERS (Energy Recovery System) can be used for the Destruction of PFAS in Biosolids. PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) are a class of anthropogenic chemicals containing fluorinated carbons with a charged functional group (usually carboxylic acid or sulfonic acid) that is extremely resistant to degradation.

BioThelys™ process is an anaerobic digestion system enhancement. The use of low pressure and low temperature steam applied to dewatered biosolids causes the microbial cells to rupture and therefore increases the soluble fraction of COD that is available for digestion. This increases both the rate at which digestion occurs and the amount of solids that will be reduced; the net result being greater biogas production. 

Exelys™ is a continuous thermal hydrolysis system. Each treatment train uses one reactor with progressive cavity pumps that hold the biosolids at the required pressure and temperature for thermal hydrolysis for the required amount of time in order to meet Class A requirements.

BIOMET™ is a wet methanization process leveraging on an external agitation system with continual crushing guaranteeing energy and environmental performance by combining hydrolysis and anaerobic digestion.

By diverting more organic material to the anaerobic digester, Ecrusor™ is a key tool to increase a plant's biogas and energy production capacity. Ecrusor helps turn waste facilities into resource recovery facilities by converting more waste into energy in a circular economy approach to waste treatment. 

Struvia™ prevents uncontrolled struvite precipitation during wastewater treatment. This Veolia process uses a patented mixing system, TurboMix™, to produce and separate struvite crystals within a single reactor. Struvia™ is compact, resource efficient, and produces a granular end product consisting of magnesium ammonium phosphate (MAP) crystals.

Net Zero Resource Recovery

Hermitage Municipal Authority undertook a major upgrade of its solids handling facility to increase treatment capacity and to boost biogas generation.





Class A Solution

Upgrading the Picnic Point Wastewater Facility with Veolia's BioCon biosolids dryer has reduced the amount of biosolids to be disposed of as well as producing a Class A biosolid.





Effective Phosphorus Removal & Sludge Drying

Hydrotech Discfilters provide effluent polishing, phosphorus removal, and wastewater reclamation while the BioCon provides sludge drying at the Western Wake Regional Water Reclamation Facility in Durham, NC.





Thermal Energy Savings

BioCon Dryer and ERS systems allow for a small footprint that contains odors and meets the Class A requirements while also saving the plant 70-80% of the required thermal energy that leads to a smaller carbon footprint.
