PFAS Management & Treatment

• We characterise PFAS-contaminated waste streams to determine compound types, concentrations, and exposure pathways, forming the basis for targeted treatment strategies.

• Advanced treatment technologies, including adsorption, thermal destruction, and physico-chemical processes, are applied to neutralise or remove persistent PFAS compounds safely and effectively.

• Systems are engineered to control emissions, leachate, and secondary residues, ensuring full compliance with environmental, occupational, and air quality regulations.

• PFAS management is integrated within broader waste handling and site remediation programs, enabling secure storage, handling, and disposal of high-risk materials.

• We verify performance through rigorous monitoring and reporting, producing auditable results that align with regulatory and client requirements.

• Our approach transforms highly persistent PFAS liabilities into managed, defensible outcomes, protecting human health, the environment, and operational continuity.

NORM Management & Guidelines

• We assess naturally occurring radioactive material (NORM) across industrial facilities, determining concentrations, exposure pathways, and potential radiological risks to workers, operations, and the environment.

• Waste streams and residues are classified according to international and regional regulatory frameworks, including IAEA, local nuclear safety regulations, and industry best practices, forming the basis for tailored management strategies.

• Handling, containment, and storage systems are engineered using radiation shielding, segregation protocols, and controlled access to minimise occupational exposure and environmental release.

• Comprehensive monitoring programs, including gamma spectroscopy, in-situ surveys, and periodic sampling, verify radiological conditions, ensuring compliance and providing defensible, auditable records.

• Treatment and disposal pathways are designed to safely manage NORM, integrating decontamination, encapsulation, and decay-in-storage solutions where applicable, aligned with regulatory approval and site-specific operational constraints.

• Operational protocols cover transport, treatment, emergency response, and decontamination, integrating site-specific workflows with regulatory, HSE, and industry best practices.

Brine & Blowdown Water Treatment

• We characterise brine and blowdown water streams to quantify salinity, hardness, dissolved solids, metals, organics, and other contaminants, establishing treatment requirements tailored to site-specific conditions.

• Advanced treatment technologies, including reverse osmosis, ion exchange, membrane filtration, and chemical conditioning, are applied to remove salts, hardness, and targeted contaminants efficiently.

• Our treatment processes are designed to optimise water recovery, minimise scaling and fouling risks, and ensure compliance with environmental discharge standards.

• We implement integrated monitoring and control systems to track water quality parameters, chemical dosing, and system performance in real time, ensuring consistent treatment efficacy.

• Concentrate and residual streams are managed through engineered disposal, recycling, or further treatment solutions, mitigating environmental impact while meeting regulatory and operational requirements.

Off-Spec Treatment

• We assess off-specification materials to determine chemical composition, physical properties, stability, and potential hazards, establishing tailored treatment pathways.

• Our specialists apply advanced techniques - such as chemical neutralisation, blending, segregation, and stabilisation - to restore materials to compliance or prepare them for safe disposal.

• We engineer treatment systems that control emissions, manage reactive hazards, and minimise secondary waste, ensuring both safety and environmental compliance.

• Our team continuously monitors temperature, pH, viscosity, and other critical parameters to maintain process consistency and achieve effective remediation of off-spec materials.

• Treated outputs are conditioned for compatibility with downstream processing, recycling, or approved disposal routes, aligning with regulatory requirements and site-specific constraints.

Oil-Spill Treatment
