Hazardous liquid waste treatment

Hazardous liquid waste remains one of the most challenging and expensive waste streams to manage, process and dispose of safely.  Our forced circulation evaporators concentrate difficult liquids, minimize volume and enable safe disposal or further treatment.

Hazardous liquid waste is difficult and costly to manage, but our forced circulation evaporators reduce its volume, ensuring safer disposal and easier treatment.

Why hazardous liquid waste treatment matters

Hazardous liquid waste from industries like oil, chemical, mining and nuclear operations often contains metals, oils and toxins that can’t be safely discharged. Without proper treatment, it risks long-term contamination of water and ecosystems. 

By treating hazardous liquid waste directly at the source, you minimize the risk of spills and leaks, safeguard local water bodies, and contribute to a more sustainable and responsible use of natural resources.

Industrial solutions from Swedish Exergy

Automotive and Aerospace Industries

Automotive and aerospace production generates wastewater containing oils, fats, cleaning agents and toxic chemicals.​ Our solutions treat these pollutants efficiently, helping you protect the environment and secure sustainable water management in your plants.

Workshops and Steel Manufacturing

From machining, welding, and surface treatments to rolling mills, workshops, and steel manufacturers produce wastewater requiring specialized handling. To address this, our tailored solutions manage cooling liquids and byproducts, all while maintaining compliance with environmental standards.

Solvent and chemical recovery

Many industrial processes discharge wastewater that still contains valuable solvents.With our recycling solutions, you can recover these solvents, reduce production costs and minimise waste while improving resource efficiency.

Oil emulsions and hazardous liquid waste

Our technologies are designed to treat oil emulsions from refining and transportation, as well as hazardous liquid waste from chemical production and battery handling.This ensures safe disposal, reduced environmental risk and full regulatory compliance.

Nuclear wastewater treatment

Radioactive wastewater from nuclear power plants, decommissioning projects, nuclear vessels and submarines demands precise and reliable treatment.Our advanced systems remove radioactive contaminants and help you operate safely and responsibly over the long term.

Waste dump sites and leachate

Leachate from waste dump sites often contains harmful chemicals and heavy metals that threaten groundwater and nearby ecosystems.Our treatment systems neutralize these pollutants and protect both local communities and natural environments.

Key benefits of hazardous liquid waste concentration

Lower disposal costs
Volume reduction means fewer transports, smaller storage needs and reduced fees for final disposal.

Reliable operation
Forced circulation keeps the liquid moving through the heat transfer surfaces, which limits fouling and supports stable, continuous operation with minimal downtime.

Handling of difficult liquids
The technology is well suited for viscous, particle‑laden and mixed hazardous streams that are not compatible with conventional evaporators or simple separation methods.

Safer handling and reporting
Concentrated and stabilised waste is easier to manage within regulatory frameworks, including monitoring, documentation and reporting to authorities.

Compliance, safety and sustainability

Our hazardous liquid waste treatment solutions are designed to support strict regulatory requirements in highly regulated industries such as nuclear, chemical and energy.​​

We help you document performance, monitor critical parameters and integrate treatment systems into existing processes.

Together, we build solutions that align with your ESG targets, reduce your environmental footprint and strengthen your sustainability reporting.

Proven technology and project experience

Swedish Exergy has delivered evaporation systems for hazardous and difficult liquids across several industries, including oil and gas, chemicals, metals and nuclear waste.

Our experience covers process design, engineering, installation and support. The systems are built for continuous operation and can be connected to existing utilities and waste handling infrastructure.

Integration with other Exergy technologies

Many sites manage both hazardous liquids and wet residues such as sludge or biomass. By combining evaporation with our superheated steam drying technology, you can treat liquid and solid fractions in one integrated concept.

The ExergyPSSD®, Exergy pressurized superheated steam dryer, dry wet solids efficiently, enabling recovery of energy and material value and further reducing the amount of waste that requires final disposal.
