Targeted contaminant and nutrient removal
Precision removal of nitrogen, phosphorus, PFAS and micropollutants
Industrial wastewater streams today include persistent nutrients, emerging contaminants, and metals that demand targeted solutions. We enable industry to achieve consent levels for nitrogen (nitrate/ammonia), phosphorus, PFAS, micro-pollutants, and dissolved metals using integrated, high-performance equipment tailored to your specific water matrix.
Modern discharge consents increasingly target total nitrogen and ammonia to reduce eutrophication risk. We support both standard activated sludge and Moving Bed Biofilm Reactor (MBBR)-based biological treatment, supplying all the core technologies needed for effective nutrient removal:
- Turbocompressors, diffusers, and submersible mixers for energy-efficient, precise aeration and mixing are critical for stable ammonia and nitrogen reduction in any biological process
- Energy-efficient Return Activated Sludge (RAS) pumps to optimize recirculation in conventional activated sludge systems
- Monitoring and controls automate process optimisation and ensure reliable compliance
With regulators lowering phosphorus limits to protect receiving waters, robust chemical and physical processes are vital:
- Chemical dosing systems deliver accurate, responsive dosing of ferric, alum, or alternative precipitants
- Static mixers and pipe flocculators ensure thorough chemical blending
- Lamella settlers, Dissolved Air Flotation (DAF) units, disc filters, drum filters, sand filters, and cloth filters capture and remove the resulting solids, reliably achieving very low residual phosphorus
Activated carbon, whether Granular Activated Carbon (GAC) or Powdered Activated Carbon (PAC), efficiently adsorbs PFAS, pharmaceuticals, and other micro-pollutants from industrial wastewater. We support both approaches:
- Activated carbon filters: Fixed-bed GAC systems for robust, continuous removal of PFAS and trace organics
- Powdered Activated Carbon (PAC): Prepared as a slurry, thoroughly mixed into the water with our static mixers, pipe reactors, or tank mixers for effective contaminant adsorption
- Separation: Spent PAC is removed using DAF units or cloth filtration; if needed, it’s condensed with Lamella sedimentation while Zickert scrapers transfer settled PAC to extraction.
- Sludge handling and carbon disposal: Dewatered PAC, along with exhausted GAC, is sent for off-site incineration by specialist contractors, ensuring secure destruction of adsorbed contaminants and regulatory compliance. Our integrated technologies ensure treated water quality suitable for advanced quaternary treatment, enabling future compliance and water reuse.
We support removal of regulated metals:
- Oxidation and precipitation systems convert dissolved metals into insoluble particles ready for removal
- Static, pipe and tank mixers provide thorough chemical contact for consistent performance
- Robust industrial separation technologies and filters capture metal solids, safeguarding downstream operations
