BioMix-AD Anaerobic Digester Mixing Systems provide uniform mixing of anaerobic digester tank contents by firing programmed, short-duration bursts of compressed biogas through patented, engineered nozzles located near the tank floor. The mixing parameters may be adjusted to optimize mixing and power utilization, either through operator input or automated process feedback.
BioMix-AD enables facilities to meet sludge disposal regulations and reduce energy costs, while reducing their carbon footprint and recovering biogas as a renewable energy source.

BioMix-AD differs from piston bubble, draft tube, lance, and other anaerobic digester gas mixing systems. The technology’s integrated approach results in superior volatile solids destruction, increased gas production, and temperature uniformity, all with lower energy requirements.
A centralized biogas compressor charges the receiver tank, which supplies compressed biogas to the intrinsically safe valve module. The valve module controls the firing parameters, delivering short-duration bursts through engineered nozzles. Large biogas volumes expand upward and outward, providing uniform mixing of tank contents. The firing parameters in combination with the distributed nozzle locations address differing sludge feed positions, feed duration, and outlet positions, as well as increased sludge viscosity.
