The BAT Wastewater Directive affects numerous industrial sectors in which relevant quantities of wastewater are produced. These include, in particular, metalworking/processing (e.g., CNC machining, surface treatment), automotive manufacturing, aerospace, surface technology, energy supply, the chemical industry, food and beverage production, mechanical/plant engineering, the manufacture of electronic and optical devices, electromobility/battery production, healthcare, and the recycling industry. In all these areas, wastewater treatment based on BAT recommendations can help to reuse water multiple times in the production process and improve discharge values. MKR Metzger offers modular solutions for this purpose, such as evaporators, filtration systems, and foreign oil separators, which can be individually adapted to the industry.
evaporators can operate 24/7 because many systems are designed for continuous industrial use and are controlled automatically. They deliver stable performance even with fluctuating material flows and require little maintenance. This makes them easy to integrate into existing plant structures.
Evaporation is a safe way to treat wastewater because critical ingredients remain in the concentrate and the distillate is significantly purified. The separation is physical and delivers reproducible distillate quality . This allows even complex wastewater streams to be treated reliably.
A wastewater analysis for plant design is the basis for selecting the appropriate process technology and modules . This is the only way to ensure that the plant is correctly designed in terms of composition, quantities, and fluctuations. This ensures stable results and safe operation in the long term.
Wastewater technology that complies with BAT offers companies several advantages: it helps them comply with emission and discharge limits, conserves resources through recycling, and can significantly reduce operating costs. In addition, it is based on the latest technology, which makes sense in the long term with regard to future legal changes. At MKR Metzger, processes such as ultrafiltration, evaporator systems, and oil separation are combined in such a way that both water quality and energy efficiency are optimized. This results in solutions that meet technical requirements while placing environmental considerations at the forefront.
Evaporators for Disposal are useful because they can treat different wastewater streams in a stable and legally compliant manner. This facilitates the processing of changing waste streams and supports compliance with relevant regulations. At the same time, processes become more efficient and easier to standardize.
Processing KSS emulsion on site significantly reduces wastewater volume and disposal costs, especially in machining production . At the same time, distillate can be used as process water , reducing the need for fresh water. This improves the ecological balance and maintains process reliability.
BAT stands for “Best Available Technology” and refers to technologies and processes that represent the current state of the art in environmental protection. In the field of BAT wastewater, this includes systems and processes that enable particularly efficient, resource-saving, and environmentally friendly treatment of industrial wastewater. These processes are defined and described in the EU's BREF documents (Best Available Techniques Reference Documents). By following the BAT recommendations, companies can improve their wastewater quality and more easily comply with environmental regulations. Examples of such processes include modern evaporator systems or filtration technology from MKR Metzger, which are designed for high efficiency and durability.
