BAT solutions
Best Available Techniques define how industrial wastewater must be treated in Europe. We help you understand your requirements and design treatment that meets them.
BAT (Best Available Techniques) refers to the most effective and advanced methods for preventing or minimising environmental impact while remaining economically and technically viable. In water treatment, BAT defines the standards and technologies required to achieve high levels of pollution reduction, efficient resource use and compliance with environmental regulations such as the EU Industrial Emissions Directive.
BAT requirements are closely linked to the EU Industrial Emissions Directive (IED), which defines the regulatory framework for industrial pollution control. For industrial operators, this means wastewater treatment must be designed according to sector-specific BAT conclusions and aligned with BAT-AEL performance levels (BAT Associated Emission Levels), depending on the applicable industry and permit requirements.
Read Directive 2010/75/EUBAT compliance is not defined by one universal discharge limit. Instead, BAT sets a framework of best available techniques and expected performance levels that vary by industrial sector and wastewater composition. In practice, meeting BAT requires a combination of proven treatment technologies, correct process design and reliable performance verification based on real wastewater behaviour.
Compliance roadmap
Identify the BAT conclusions, BAT-AELs and local permit limits that apply to your site.
Sample and analyse each wastewater stream to understand its real behaviour.
Run electrocoagulation tests on your own water and document removal rates.
Combine the right treatment steps for compliant discharge or reuse.
Commission the plant and provide performance documentation for your permit.
Key parameters
FjordFilter's treatment systems address the main parameters commonly associated with BAT discharge requirements. Our solutions can be designed both for compliant discharge and, when applicable, for reuse as technical water.
Up-to values. Results vary with water composition, so we always test on your own water before recommending a solution.
Industrial wastewater typically requires multiple treatment steps — from particles and oils to dissolved organic and inorganic fractions.
To reach BAT compliance, treatment must be adapted to each wastewater fraction. FjordFilter's process is chemical- and membrane-free. Our goal is to select the most effective and economically viable treatment line for each site.
| Treatment step | Main purpose | Typical contaminants addressed |
|---|---|---|
| Sedimentation, filtration & flotation | Mechanical separation and solids removal | Particles, TSS, sludge, suspended matter |
| Emulsion handling & oil separation | Break and separate stable oil fractions | Oil & grease, emulsified oils, hydrocarbons |
| Aeration & stripping | Remove volatile compounds and improve water quality | VOCs, dissolved gases, selected organic fractions |
| Electro-coagulation & absorption (EC) | Coagulation/flocculation and pollutant capture | Metals, colloids, complex organics, oil residues |
| Electro-oxidation (EO) | Advanced oxidation of persistent compounds | Dissolved organics, colour, difficult-to-degrade pollutants |
| Polishing (activated carbon) | Final purification and trace removal | Micropollutants, residual COD, odour, PFAS/PFOA |
BAT compliance can also improve industrial efficiency. FjordFilter solutions help customers reduce costs and increase circularity through:
