VTA
mudinator®

Ultrasound treatment and preconditioning for environmentally friendly optimisation of sludge dewatering.

VTA mudinator

A change in sludge structure with low energy input can be achieved using the VTA mudinator®.

Ultrasound treatment using the VTA mudinator® can change the structure of the sludge thereby improving the effect of the polymer. 

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.

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.
