Anaerobic reactors (digesters) allows a high degree of reduction of organic pollution in the treatment of concentrated liquid waste. 


Gastight glass-fused to steel tanks represent superior surface protection from corrosion by liquid and gaseous fermentation products. They are suitable for both cold and heated reactors with a working temperature of up to 60 ° C.

Digesters design

The reactor design allows for the mixing of contents with the built-in mixer, external pumps or gas.

Also, the internal equipment of the reactor can be adapted to the requirements of optimal processing of a particular substrate, which is most commonly a sewage sludge, excrements of farm animals or waste water from the pharmaceutical and food industry.

We supply 2 types of digesters:

  • Tank with fixed glass-fused to steel roof
  • Tank with mounted two-membrane roof with gasholder function

Inspection and reconstruction

We are a successor of the Vítkovice manufacturer of tanks; thus we are able to ensure any reconstruction of the original tanks.

Repairing the old Vítkovice tanks

With use of our production project documents of the original tanks, we are able to ensure the safety of the works carried out and to ensure a suitability of the planned reconstruction. We as a traditional producer of enamelled tanks are offering inspections of the existing tanks and assessment of their current technical conditions with respect to their further utilization with the specific type of the liquid and their expected lifetime.


  • assessment of the current technical conditions of tanks
  • information on the expected lifetime of tanks
  • assessment of the options and proposals of the further utilization of tanks
  • recommendation of suitability of tanks for storage of the specific media
  • complete reconstruction

Based on many years of experience, we will propose the best solution for the possible repairs or reconstructions to extend the tank lifetime.
