Product Description
Dry Fermentation technology differs from traditional "wet digester" tank systems that utilize liquid feedstock and physically stir and agitate materials with moving parts. During the fermentation process, no further mixing, pumping or stirring is necessary inside the digester, nor is further material added.
The fermenters are characterized by having a generally common shape of the building. They are filled and unloaded using the front loader. Dry fermentation is a discontinuous process in which is the material in the fermentation boxes heated to operating temperature and spraying by the processing liquid. There is a depletion of oxygen in a short time and start on the process of anaerobic fermentation and biogas production in fermenters. The material remains approximately 4-5 weeks in the process. After this period biogas production is decreasing and the material is removed. Excessive percolation liquid is collected in a drainage system, temporarily stored in the percolation tank, and then re-sprayed over the biomass in the digester.
The residual material can be used as valuable organic fertilizer or can be further composted. Produced biogas is burned in a cogeneration unit which produces electricity and heat. Dry Fermentation is best suited for operations that process organic waste with a total solids content greater than 25%, including: Food waste, Yard clippings, Dry manure on bedding,Other high-solids waste.
Advantages:
1) High total solid content (TS) in digested material can be up to 25-50%. Thus applicable to single or mixing raw material, e.g. municipal organic wastes, straw, livestock & poultry manures, etc.
2) Small fermentation tank, no requirement of a slurry storage tank, and the slurry can directly be applied as organic fertilizer for use after dry digestion
3) The possibility of processing non-homogeneous material with lower quality and containing different additives without pretreatment (technology suitable for energy recovery from biowaste)
4) Low energy consumption of system due to no operating equipments
5) Low maintenance cost, high reliability of automation control and low degree of reliance of system on mechanical equipments
6) High biogas yield (100-180 m³/t), high methane content in biogas (60%-70%) and low H2S content (20-50 ppm)
7) Modularized design and convenient capacity expansion
8) High economic benefits & profits from power and heat generation, organic fertilizer, treatment of extra municipal wastes, etc.
