Vacuum evaporator

Vacuum evaporators are treatment plants that distill wastewater under negative pressure to separate water and pollutants.
MKR Metzger deliberately does not rely on vacuum technology, but on robust, fully automatic Evaporator systems with mechanical vapor compression and heat recovery. This solution offers the following advantages: Less wear on vacuum pumps and seals Energy efficiency through heat recovery Hygienized condensate – virtually free of salt, oil, and heavy metals Fully automatic operation with minimal operating effort MKR evaporator systems can help companies implement the recommendations of the BAT Wastewater Directive for Industry in an economical and sustainable manner – for example, for the recirculation of process water or the reduction of disposal costs.

Vapor compression

In vapor compression, a distinction is made between mechanical vapor compression and thermal vapor compression. In mechanical compression, the vapor is compressed using a compressor. In thermal vapor compression, the vapor is brought to a higher temperature using steam or a vapor evaporator before being returned to the distillation column.

Vaporizer

A vapor condenser allows you to treat process water in an energy-efficient manner thanks to vapor compression. The ET evaporator series from MKR Metzger also stands out thanks to its particularly low energy consumption and a number of advantages over other technologies. In contrast to treatment with a vapor evaporator, conventional process water treatment leaves too many heavy metals in the process water, regularly resulting in limit values being exceeded. Furthermore, unlike vapor evaporators, conventional processes require labor-intensive monitoring.

Wash Bath Care

Wash bath care describes the continuous cleaning and stabilization of washing and degreasing baths in industrial cleaning processes. The aim is to remove oils, greases, particles and emulsions from the medium, maintain stable cleaning quality and reduce bath changes. MKR uses technologies such as ultrafiltration with ceramic membranes for this purpose.

Zero Liquid Discharge

ZLD (Zero Liquid Discharge) refers to the complete recycling of process water, whereby no liquid waste water is discharged. Instead, the water is reused and only a significantly reduced volume of concentrate is disposed of.
