Bulking and floating sludge

Massive appearance of filamentous bacteria can cause bulking or floating sludge and consequently lead to contamination of the effluent.

The problem

Bulking and floating sludge impair sludge settling considerably and thus lead to a contamination of the effluent.

Floating sludge

Impaired settling

The cause

Specific factors can cause massive growth in filamentous bacteria. The resulting increase in sludge surface leads to an impairment of sludge settling.

The solution

Using the VIT® gene probe technology, filamentous bacteria can be identified and quantified.

Conventional

With conventional identfication methods, filaments can only be identified with difficulty or cannot be identfied at all.

VIT®

VIT® gene probe technology allows for identfication and quantification of filamentous bacteria.

Process adjustment

By attribution of filament types to process parameters, changes in process management can be applied.

Regular monitoring with VIT®

By regular monitoring with VIT®, filaments can be tracked with high specificity. Countermeasures can be taken even before problems like slude bulking and foaming become evident.

Continuous monitoring can either be performed directly on site with our products or as a service in the shape of our yearly packages, which offer an excellent price-performance ratio.

Dick Eikelboom and vermicon

With his work and his development of an identification key for filamentous bacteria, Dick Eikelboom set a milestone in identification and control of filamentous bacteria.
In the late 1990ies and early 2000s Dick worked in close cooperation with vermicon on the development of gene probes for the most significant filamentous bacteria, which represented the next milestone in the detection of filamentous bacteria.

The six-year cooperation in the international research projects "MACOBS" and DYNAFILM led to the discovery of novel and important filamentous bacteria and allowed for a reliable first-time detection and monitoring of these bacteria with VIT® gene probes.
