Ultrasound treatment using the VTA mudinator® can change the structure of the sludge thereby improving the effect of the polymer.
A change in sludge structure with low energy input can be achieved using the VTA mudinator®.
The more effective charge balancing with the polymer produces more stable floc that is able to release water faster and consequently an optimised dewatering result is achieved.
In combination with the sludge conditioning agent VTA Biocitran®, synergy effects occur during the ultrasound treatment. The treated sludge can be dewatered much more efficiently and polymer consumption can be reduced.
A change in sludge structure with low energy input can be achieved using the VTA mudinator®.
Advantages
Treatment with ultrasound
The sludge is treated with ultrasound just before the polymer is added.
Better charge balance
Changing the structure of the sludge produces a better charge balance with the subsequent polymer.
Better dewatering
The result is a shear-stable floc. Consequently: There is better dewatering.
Very low energy use
No disintegration takes place – very low energy use
The innovative VTA mudinaor® is based on many years of experience with ultrasound in the patented reverse flow disintegration (GSD)
Our VTA mudinator® also uses ultrasound to treat the sludge. In contrast to disintegration, the cell structures in the sludge are not broken up. The sludge structure is, however, modified to produce optimum charge balancing with the polymer that is subsequently added.
Advantages
improved dewatering due to release of interstitial water
dewatering result is increased (up to 5 percentage points)
polymer requirement is reduced significantly
backcharge on the plant ecosystem is reduced in combination with VTA Biocitran®
lower costs due to significant reduction of the volume of sludge requiring disposal
optimisation in the addition of conditioning agents
shear stable floc
Solution
The challenge
Deficient dewatering:
Untreated sludge retains large amounts of water, drying becomes inefficient
Our solution
VTA mudinator®
The VTA mudinator® changes the structure of sludge by using ultrasound prior to dewatering. This enables a better charge balance with the polymer
The result
Improvement in dewatering of up to five percentage points
- Saving of disposal costs
- Optimisation of conditioning agents and addition of polymer
Recommended combination
VTA mudinator® combined with Biocitran®
Recommended combination
VTA mudinator® combined with Biocitran®
Combining these two innovative products sets new standards. The dewatering properties can be achieved even more easily together with the application of VTA Biocitran®. Synergy effects can be achieved when Biocitran® is introduced into the digested sludge (prior the polymer is added). The result: Effective dewatering of the treated sludge and reduced or unchanged polymer consumption.
VTA mudinator® in practice
VTA mudinator® and VTA Biocitran®
Two world firsts from VTA set new standards in the dewatering of sewage sludge, making utilisation and disposal much more cost-effective.
Cost-effective sludge dewatering
The VTA mudinator® is a world first in the dewatering of sewage sludge.
Reducing disposal costs with the VTA mudinator®
Optimum sludge dewatering is more important than ever – not least because of steadily rising disposal costs.
