LM^™ Mixer

When Less is More

The LM^™ (Linear Motion) Mixer is a revolutionary anaerobic sludge mixing system that ensures thorough mixing, uniform temperature, solids distribution, and microorganism contact.

This system can be used in existing and new anaerobic digesters, customized to suit specific tank designs and applications. And it requires minimal maintenance, making it a cost-effective choice for wastewater treatment plants that need to enhance biosolids management operations.

LESS ENERGY MEANS LOWER COSTS

THE PROBLEM

Effective biosolids management and anaerobic digestion are critical for wastewater treatment plants. Inadequate mixing can lead to operational upsets, costly downtime, and unpleasant odors. Traditional mixing methods often require frequent maintenance and degassing or dewatering of the digester.

THE OVIVO SOLUTION

The LM Mixer provides a reliable and efficient solution for anaerobic sludge mixing. With its linear motion design and ragless construction, it effectively mixes various municipal sludge types in anaerobic digestion applications. Additionally, energy costs are significantly lower compared to conventional mixers due to its low horsepower motor.

HOW IT WORKS

Unlike traditional mixer systems, the LM Mixer produces isotropic (uniform) mixing because of the combined effect of oscillating velocity and 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.

Plants with a well-mixed digester see many performance and operational benefits, such as a higher degree of volatile solids reduction (VSR) and biogas production. The use of the hydro-disk also prevents the buildup of rags and associated failures found in conventional systems.
