Markets & Applications

Water and Wastewater Treatment

Water and wastewater treatment are essential services that provide vital resources while protecting human and environmental health.

These processes generate treated water alongside residuals, including sludges and spent media, that contain a concentrated suite of contaminants that must be disposed of responsibly. 

Traditional disposal practices such as landfilling and incineration can be costly and do not fully remove hazardous contaminants, thereby creating risk.

AirSCWO provides a compelling solution that can transform these residuals into distilled water, minerals, and recoverable heat while destroying contaminants of concern like PFAS. Additionally, SCWO can be operated autothermally, requires a small footprint, and can be easily integrated into existing treatment plant infrastructure. 

 

Potential applications in the water and wastewater treatment markets include: 

  • Sustainable disposal of sludges, slurries, and biosolids
  • Destruction of organic contaminants like PFAS and contaminated treatment residuals
  • Management and disposal of long accumulated water and wastewater treatment residuals (i.e. lagoon solids)
  • Elimination/treatment of leachate or the byproducts of its treatment from harmful organics and PFAS 

Defense

The defense industry has produced a variety of wastewater streams that contain valuable yet difficult to dispose of contaminants. 

 

The fabrication of specialized components, cleaning of military equipment, day to day base operations, and aqueous film-forming foam (AFFF) are just a few of the many waste vectors that pose problems for defense agencies. 

 

Bases around the world operate their own water and wastewater treatment plants, generating highly concentrated and contaminated residuals that need to be managed and disposed of with minimal impact to the surrounding environment. 

 

Potential applications in the defense sector include:

  • Collection and elimination of stockpiled AFFF
  • Destruction of contaminated water and wastewater treatment residuals like granulated activated carbon and ion exchange resins
  • Remediation of contaminated soils
  • Destruction of spent munitions such as chemical nerve agents or volatile explosives
  • Disposal of seized controlled substances
  • Diversion of organic and chemical wastes from burn pits

Industrial Waste Management

During the manufacturing of bulk goods, wastes are produced that can be difficult to dispose of due to their moisture, volume, composition, and level of contamination.

A long list of manufacturing technologies and processes generate wet waste products that incur expenses for treatment, hauling, and disposal. These wastes must be treated to meet environmental standards at an attractive price point.

AirSCWO transforms the sludges or concentrates into distilled water, minerals, and recoverable heat while eliminating organic contaminants of concern like PFAS. The on-site installation of AirSCWO reduces hauling costs and reliance on contracts, giving manufacturers ownership and flexibility to their waste disposal practice.

Potential applications in the industrial market include: 

  • Providing a means for sustainable disposal of sludges, slurries, and biosolids
  • Enabling the takeback and destruction of stockpiled aqueous film-forming foams (AFFF)
  • Managing and destroying PFAS impacted waste streams 
  • Producing a reusable water source from wet organic and chemical wastes
  • Extracting and reusing valuable  minerals from wet organic waste streams
  • Eliminating byproducts from water and wastewater treatment (i.e. adsorbents like activated carbon or foam fractionate)

Pharmaceuticals

The pharmaceutical industry generates large volumes of hazardous wet wastes from the preparation of raw materials, drug synthesis, cleaning and sanitizing, and final product preparation. 

 

As existing water treatment technologies are not suited or designed to remove these contaminants, the waste must be incinerated at the cost of natural gas and impacting the surrounding wildlife and communities.

AirSCWO’s aptitude at organics elimination can be put to full use in the pharmaceutical industry, with its non-selective destruction of organic contaminants such as residual active pharmaceutical ingredient (APIs). This contaminant destruction is matched with the conversion of large volumes of wet waste to clean water, minerals, and recoverable heat.

Potential applications in the pharmaceutical sector include:

  • Managing and eliminating contaminants in concentrated and dilute solvent wastes
  • Enabling the sustainable conversion of water treatment residuals (biosolids/absorbents/membranes) to value-added products
  • Recovering valuable catalyst metals
