• Stable and highly effective sludge mixing system
• Low power costs
• Low maintenance
• Proven, reliable technology

Anaerobic Digestion is highly dependent upon effective mixing. When tank contents are inadequately mixed, stratification occurs and tank volume is not properly utilized. But rotary mixers can be ineffective on thicker sludges and consume excessive power.

• Significant energy savings compared to conventional sludge mixing systems
• Ovivo’s LM™ mixer is a proven technology that achieves over 90% active tank volume
• Ragless design and low cost maintenance
• Capital and installation cost savings compared to rotary mixers
• Capable of mixing viscous fats, oils and greases (FOGs)

Wastewater treatment facilities require thorough and complete sludge mixing to ensure uniform temperature, solids distribution and microorganism contact to increase gas production and maximize the solids destruction. The LM mixer innovative technology allows achieving a unique and efficient mixing pattern throughout the tank while keeping energy requirements low.

The equipment is suitable for both new and existing tanks, at a fraction of the installation costs of conventional mixing technologies. Computational Fluid Dynamics (CFD) are used to custom design a system that will meet your mixing needs, by varying the frequency, stroke and disk size. Furthermore, the use of our hydro-disk prevents the build-up of rags and associated failures found in conventional systems.

Unlike other mixer systems, the LM mixer produces isotropic (uniform) mixing due to the combined effect of oscillating velocity coupled with pulsating pressure waves. This motion is created by the controlled up and down movement of a ring shaped hydro-disk (inside the tank) driven by an innovative cam-scotch-yoke operating system (above the tank). This concurrent action couples the oscillating pressure wave and velocity to enhance mass transfer and produce a uniform mixture of the tank’s contents.

PROVEN TECHNOLOGY THAT OFFERS SIGNIFICANT COST SAVINGS:

• The LM mixer does not rely on induced flow to create the necessary mixing.
• Multiple LiCl tests performed by various consultants, in several applications and conditions have demonstrated an active tank volume of 90% or greater.
• Installation of a single mixer can be completed in a day or less.
• No additional piping or core drilling is needed
• Suitable for both new or existing tanks
• Little to no changes are needed on existing structures
