Liquid Humus Centrifuge

Liquid humus fertilizer – How is it made?

 

To produce liquid humus, you first mix organic humus with water to make a slurry. After a predetermined residence time, you separate the water from the humus biomass. The separated water carries all the minerals and nutrients from the humus. This fluid is liquid humus.

Large scale production of liquid humate

 
For large scale production, mechanical separation of humus biomass is the most efficient way to produce liquid humus.
 
An industrial centrifuge separates humus biomass from the water on a commercial scale. High centrifugal force is very efficient for separating biomass solids from the slurry.
 
A decanter is a high capacity, flow-through type centrifuge, which can separate a large proportion of humus biomass (up to 50%) from water. This continuous process produces liquid humus fertilizer and dry humus biomass.
 
The centrifuge model shown is an Alfa Laval NX 314 Stainless Steel Decanter Centrifuge for continuous humus dewatering. The model specifications are-

Humus clarifier centrifuge

 
The separated water from the decanter has small amounts of suspended humus particles. The separation of these particles is necessary to produce the final liquid humate fertilizer.
 
A liquid humus centrifuge exerts up to 12,000 g’s of centrifugal force. These centrifuges separate particles down to 1 µm level. A disc stack type ‘polishing’ centrifuge, downstream of the decanter, produces clear centrate – ready for sale!
This production step of centrate clarification is like the one used for algae harvesting.
 
Dolphin Centrifuge has tested multiple liquid humus samples through our pilot-scale centrifuges. Contact Dolphin to discuss how an industrial centrifuge could enhance your humus fertilizer production.
