Tray Motion Mixer
Core to Efficienty Improvement on Digestion Chamber for Sludge Reduction

1. New Conceptualized, Vertical Mixing
2. Low Energy for Green Growth
3. Lighter and Low Vibration to achieve Structural Safety

Specifications

• Applied Power : 11KW
• Maximum Typical Stroke : 40cm
• Load : about 4.7ton

Revision of the Sea Pollution Prevention Law Cmplete ban on the discharge of livestock excretion and waste sludge started in 2012

1. The effectivation of London Protocol in 1996
2. The standard for Ocean Emission of waste matter (including sludge) has been strengthened
3. The method for processing sludge within land is needed
4. Need for Waste Sludge Reduction has emerged
5. Propulsion of High efficiency Digestion Chamber(Reduction of Sludge and utilization of Bio Gas)

What is Tray Motion Mixer?

It is to create sufficient flow within the digestion chamber and improve digestion efficiency through Vertical Motion for impeller so that the equipment and maintenance cost are to be reduced.

Joint Research of Anaerobic Digestion Mixer with Daegu Metropolitan City Environmental Installations Corporation
