Optimum sewage sludge treatment, stable digestion operation and reduction of costs – this is what reverse flow disintegration (GSD) with ultrasound, a patented process from VTA Technologie GmbH, has to offer.
In VTA GSD, ultrasonic transducers digest the thickened sludge flowing through the disintegration reactor.
The patented disintegration system with ultrasound (GSD) is mainly used to treat thickened sludge (excess or raw sludge) just before it is pumped into the digestion system.
In VTA GSD, ultrasonic transducers digest the thickened sludge flowing through the disintegration reactor. The disintegration effect is achieved using ultrasound (frequency of 25 kHz).
The aim is to optmise the digestion process: the potential of the existing sludge is exploited more effectively in the digestion system by pretreatment with ultrasound.
International studies show that 50% of all digestion plants work unsatisfactorily.
VTA Ultrasound reverse flow disintegration:
Cells are broken down. This enables an increase in the amount of digester gas and the production of electrical energy by up to 30%.
Cost savings by increasing gas and energy production
• stabilisation and optimisation of the digestion process
• reduction of sewage sludge and polymer consumption
