Solutions for wet oxidation
Due to these special requirements, diaphragm pumps are used for applications in the field of wet oxidation.
The advantages of LEWA pumps are:
- Hermetically tight
- Corrosion resistant materials
- Very high availability and reliability
- Pressures up to 1,200 bar
- Extremely precise flow rates
- High positioning accuracy
- Reproducibility through control accuracy
- Comprehensive documentation of qualification and certification
- Worldwide qualified service
Areas of application for LEWA pumps, e.g. wet oxidation
LEWA metering and process diaphragm pumps are used in the following processes:
- Low-pressure processes
- High-pressure processes
- Catalytic processes
- Supercritical wet oxidation
In these processes, chemical waste water is oxidized, that for example contains amines, dyes, cyanides, nitrobenzene, ammonium or halogens. In addition to landfill leachates, effluents that contain bacteria or biomass are treated in the same manner.
Background for wet oxidation
Process description
Wet oxidation is the destruction of organic compounds by the introduction of a suitable oxidation agent. The reaction takes place in the liquid phase under high pressure and high temperature. The goal is the destruction of critical compounds in decomposable materials.
