Some wastewater streams are simply too complex for biological or membrane-based treatment. High salinity, variable chemistry, ammonia loading and emerging contaminants can overwhelm conventional systems, creating ongoing compliance risk and escalating costs.

BeneVap is BeneTerra’s award-winning thermal vaporisation technology, engineered specifically for wastewater that other systems cannot treat. Since 2013, BeneVap has operated across Australia, New Zealand and the United States, delivering predictable, compliant performance on landfill leachate, CSG produced water, oil and gas wastewater and high-TDS brines.

Where biological and membrane systems struggle or fail, BeneVap succeeds — without filters, membranes, pressure systems or extensive pre-treatment.

Our approach to wastewater treatment with BeneVap

BeneVap is not a generic treatment system. It is applied where wastewater chemistry, operational constraints and regulatory risk make conventional treatment unreliable or impractical. Before recommending BeneVap, we assess:

  • Wastewater chemistry and variability
  • Salinity, ammonia and contaminant profiles
  • Flow volumes and seasonal fluctuation
  • Available fuels and site infrastructure
  • Regulatory requirements and approval pathways
  • Long-term disposal and liability risks

Where thermal vaporisation is the right fit, BeneVap is deployed as a stand-alone solution or integrated into a broader wastewater management strategy, delivering stable performance under changing conditions.

Wastewater challenges BeneVap is suited to

All BeneVap installations are delivered with appropriately qualified oversight, documented monitoring and clear compliance reporting.

  • What is BeneVap?

    BeneVap is a submerged combustion thermal vaporisation system designed to treat complex, high-salinity and variable-chemistry wastewater streams.

  • How does BeneVap work?

    Fuel is combusted beneath the liquid surface, transferring heat directly into the wastewater. Water is vapourised and exits as water vapour, leaving a small concentrated residual for controlled management.

  • Why does BeneVap work where biological or membrane systems fail?

    Biological and membrane systems depend on stable chemistry, low salinity and controlled fouling. BeneVap relies on thermal vaporisation, making it highly effective on waters with extreme TDS, toxicity or variability.

  • What contaminants does BeneVap remove or control?

    BeneVap delivers:

    • Over 99% ammonia removal (as ammonium bicarbonate)
    • Elimination of VOCs
    • Destruction of pathogens through heat
    • Precipitation of heavy metals
    • Containment of PFAS within the concentration vessel
  • What level of volume reduction does BeneVap achieve?

    Depending on wastewater chemistry and operating conditions, BeneVap can reduce wastewater volumes by up to 99%, significantly reducing disposal costs and long-term liability.

  • What types of wastewater can BeneVap treat?

    Applications include landfill leachate, CSG produced water, oil and gas wastewater, industrial brines, RO concentrates, animal hide processing water, mine tailings water and other high-salinity or variable-chemistry wastewaters.
