The so-called “BAT Wastewater Directive for Industry” is not a separate directive, but refers to the application of Best Available Techniques (BAT) to industrial wastewater treatment.
It is based on the European Industrial Emissions Directive (IED) – Directive 2010/75/EU – and is specified in more detail in sector-specific BAT reference documents (BREFs) and BAT conclusions. These documents contain binding emission ranges and serve as the basis for national limit values. Affected industries such as metal processing, chemicals, automotive, and food production must adapt their wastewater treatment to this state of the art in order to meet legal requirements and environmental targets. We offer industry-specific solutions for this purpose, e.g., evaporators, ultrafiltration, and foreign oil separators to reduce emission values and recycle water in the production process.

Zero Liquid Discharge (ZLD) describes a treatment concept in which liquid residual streams are reduced to the greatest extent that is technically and economically feasible. The goal is to maximize water recovery and recycling. Up to 95% water recovery possible Significant reduction in disposal costs Compliance with strict environmental regulations Sustainable solution for industrial processes ZLD systems are often based on modern evaporator technology  

Technologies, Applications and Process Solutions A Technical Guide From wash bath care to Zero Liquid Discharge - MKR develops modular solutions for the treatment of industrial process media and wastewater. Industrial wastewater treatment includes technologies for treating, separating, concentrating or recovering contaminated liquids from production processes. The goal is to reduce wastewater volumes, recover process water and keep industrial liquids in efficient circulation.

Mechanical Vapor Recompression, or MVR, is a key technology for energy-efficient evaporation in industrial wastewater treatment. In MVR evaporation, the water vapor generated during the evaporation process is not discharged as unused waste heat. Instead, it is mechanically compressed and reused as thermal energy within the process. In industrial wastewater treatment, MVR can help reduce wastewater volumes, recover process water and improve the energy efficiency of evaporator systems. Especially for continuously generated process wastewater, Mechanical Vapor Recompression is an important technology for economical and resource-efficient treatment concepts. MKR uses MVR in the atmospheric evaporators of the ET series. This creates an efficient energy loop within the system and reliably separates industrial wastewater into distillate and concentrate. MVR makes evaporation not only technically possible, but also energetically efficient.

Extend wash bath life and stabilize cleaning quality In industrial parts cleaning, continuous bath maintenance is essential for stable and cost-effective production processes. Wash and degreasing baths remove oils, greases, coolants, particles and other residues from components. As operating time increases, these contaminants accumulate in the cleaning bath. Without suitable bath maintenance, cleaning performance gradually declines. The consequences may include more frequent bath changes, inconsistent component cleanliness, increased chemical consumption, longer production downtime and rising disposal costs. Wash bath maintenance covers all measures used to continuously clean and stabilize industrial wash and degreasing baths. The objective is to keep process fluids usable for longer, maintain consistent cleaning quality and reduce unnecessary bath changes. MKR develops application-specific solutions for industrial bath maintenance – from mobile fluid maintenance, tramp oil separation and mechanical filtration to ultrafiltration with ceramic membranes. In short: Industrial bath maintenance keeps wash and degreasing baths stable for longer and helps industrial cleaning processes operate more reliably.
