Landia GasMix for biogas

Landia GasMix is a groundbreaking mixing system designed for anaerobic digesters (biogas reactors) in biogas plants.

The system has all its mechanical components located outside the tank, thus allowing all service to be performed on the GasMix system without first opening or emptying the tank. This provides obvious advantages in terms of safety, and there is also an economic benefit, as production can continue unhindered during any service work.

Let us find a solution together

Achieve better biogas quality with GasMix

Landia GasMix contributes to better biogas quality and higher methane yield. Mixing is done by recirculating a mixture of liquid and biogas in the tank.

It has been documented that the GasMix system leads to an increased reduction of volatile solids, and as a result you achieve higher biogas production. The system can be used with most tank types and for tank volumes up to approx. 350,000 ft³ and for biomasses with solids concentrations up to 14% TS.
