GasMix - Anaerobic digester mixing

The GasMix system from Landia was developed specifically for biogas plants where the unique (Patent Pending) GasMix system ensures a stable and high mixing in the anaerobic digester tanks – WITHOUT the high-maintenance big-bladed propellers which are characteristic of traditional digester mixing systems.

The GasMix method accelerates the digestion process with the result that a larger quantity of methane gas is processed more quickly than in traditional plants with mechanical mixing inside the tank.

GasMix – description of functions

When the pump is running, it draws out thick liquid from the bottom of the tank into the chopper pump, whereby all lumps are comminuted.

1. In the first stage of the mixing process, the liquid is injected into the tank’s upper half under high pressure while new biogas is being drawn from the top of the tank and mixed.
    
2. In the second stage of the mixing process the liquid is injected into the tank’s lower half under high pressure which causes vigorous mixing of the tank contents.

Continuing to build on our many years of experience

Since spring 2007 we’ve put a number of GasMix plants into operation in Europe and North America. We are also taking part in several research projects to identify ways in which we can help our customers increase their production of biogas in existing and new plants.
