Optimum agitator technology for every substrate
Biogas agitators – no off-the-peg solution
Whether it comes to the mixing pit, preliminary storage tank, fermenter, secondary fermenter or final storage: So that all technical agitating tasks can be carried out optimally in a biogas plant, it is not sufficient simply to use one type of agitator alone.
In addition to careful selection and configuration of the individual agitators for the specific agitating task and special features of the particular plant, it is also necessary to consider criteria such as energy efficiency and ease of servicing. The efficiency of a biogas plant is not determined by the purchase price alone, but in particular by the operating and maintenance costs throughout the life cycle – i.e. energy costs (consumption of self-generated electricity) and the costs of maintenance and servicing.
In addition, uncertain political conditions and substrate prices play a role, since they will change over the long service life of a biogas plant. The correct agitator technology must therefore guarantee the greatest possible flexibility with regard to the use of all kinds of input substances such as manure, grass silage or residues from the areas of agriculture, waste management and industry.
Other questions that need to be considered when elaborating technical agitator solutions are stated here merely as examples:
What liquids and solids should be agitated or mixed, and how is the substrate prepared?
What input system is used? Where is it positioned?
Are there additional inflows and outflows?
Does the fill level in the tank change, and if so to what extent?
