The functional principle of treatment in the centrifuge: Particles separated from the process water by centrifugal force compact into sludge, which is collected in the centrifuge container. Depending on the design, the sludge is discharged manually or automatically and is available for professional disposal.
The addition of suitable process water cleaners leads to effective and comprehensive solids separation and a sludge quality with a low residual water content that meets the usual disposal requirements.
“When it comes to sludge discharge, which takes place more frequently than every four hours, the automatic solution pays off because it significantly reduces the personnel effort. Depending on the capacity of the centrifuge, several vibratory finishing systems can be connected to one centrifuge,” adds Thomas Gegenheimer from his many years of project experience.
Advantages of process control in vibratory finishing with recirculation systemsIn summary, the modern OTEC process control in vibratory finishing with recirculation systems has clear advantages for the user in many respects:
- Water consumption reduced by around 90% compared to fresh water operation
- Compound savings of up to 80% compared to fresh water operation
- Sustainable reduction of waste water
- Minimum use of process chemicals (compound and process water cleaner)
- No approval requirement or monitoring requirement for process water treatment plants in the circulatory system
- No official monitoring and documentation requirements for circulatory systems
The quality of the process water as well as the quality of the compounds used ensure the continuous reliability of the entire system:
The water hardness of the process water should be between 4 and 15 °dH. In most cases, this is already given by the quality of the fresh water used. If this is not the case, this can be easily adjusted with appropriate treatment agents.
The process definition must take into account that the compounds used are recyclable in terms of their chemical composition and permanent usability in aqueous systems. The consumption is low and is documented by simple control measures and secured by manual or automatic dosing. The very low foaming tendency of the compounds used ensures process reliability even under the high mechanical demands of centrifuges.
