Low-power, high-efficiency digestion system (high-performance digestion tank agitator)

Outline

A number of local government bodies have consulted with us on issues and matters concerning the operation of digestion tanks.
Some have said the following: “As we moved from gas agitation to mechanical agitation, foaming started to occur,” and “although we changed over to mechanical agitation for the purpose of decreasing power, it caused insufficient digestion due to insufficient agitation.” The low-power, high-efficiency digestion system (high-performance digestion tank agitator) was developed to solve such problems.

With four (4) radial blades mounted at the bottom in addition to the impeller at the top of the digestion tank, it achieves high levels of efficiency when it comes to the agitation of sludge. It simultaneously realizes the consistent generation of digestion gas and a reduction in maintenance costs.

Features

Excellent agitation capabilities

Through the combination of upward flow caused by the stationary blades at the bottom and the swirling flow resulting from the rotating blades, it demonstrates excellent capabilities when it comes to agitation.

Prevention of the occurrence of dead water regions, short passes, etc.

As a result of the formation of flow pattern achieved through complete agitation mixing, it prevents the occurrence of dead water regions and short passes, and also prevents the deposition of scum and sedimentation at the bottom.

Low power

It realizes a reduction of 40% or more in terms of power. (Compared with a conventional agitator used for the same mixture)

Compatible with a variety of tank shapes

It is applicable to any tank shape, newly installed or existing.
