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 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 water on a commercial scale. High centrifugal force is very efficient for separating biomass solids from the water.
 
A decanter is a high capacity, flow through type centrifuge. It can separate large proportion of humus biomass (up to 50%) from water. This continuous process produces liquid humus fertilizer and dry humus biomass.
 
Centrifuge model shown is a Alfa Laval NX 314 Stainless Steel Decanter for continuous humus dewatering. Model specifications are:
 
– 30 GPM on Humus Water Slurry
– 95% Dry Biomass (typical)
– 15 HP Motor
– All Stainless Steel Construction
– Dimensions   8′ L x 4′ W x 4′ H
– Weight: ~ 2,500 Lbs
 
Higher capacity decanters are available  – contact Dolphin Centrifuge.
 

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.
