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.
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.
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.
Depending on the industry and type of wastewater, MKR Metzger combines various processes to implement wastewater technology that complies with BAT. These include:
Evaporator systems – energy-optimized separation of water and pollutants
Filtration – separation of fine particles, oils, and emulsions
Foreign oil separators – efficient oil-water separation
Pre- and post-treatment stages (e.g., activated carbon, ion exchange) for particularly high water quality
These modular systems can be used individually or combined to form a complete solution in order to adapt wastewater treatment to the state of the art.
In order to determine whether your plant meets the BAT requirements for industry, an analysis of the current status is usually necessary. This includes reviewing the processes used, energy efficiency, wastewater quality, and the auxiliary materials used. A comparison with the current BREF documents shows whether there is a need for modernization.
MKR Metzger offers individual consultations and practical tests for this purpose—existing plants can often be upgraded to the state of the art by retrofitting and combining technologies such as vacuum evaporation and filtration.
