Flow-through biomass pretreatment module with 30m3/hour throughput
WiseSoil Feedstock Pretreatment Module (FPM) is a solution for increasing efficiency of biogas plants. Module is based on a proprietary technology, and can be installed as add-on before any digester. Anaerobic Digestion technology can be compared to digestive system, where FPM acts as teeth, chewing the food before it gets to the stomach. Module is compatible with any digester system with substrates up to 13% solids content, and starts from only € 10 000!
Here you can see how feedstock looks like before and after treatment, provided consistently by the macerator and a pretreatment module:
WiseSoil technology integrates five pre-treatment functions in a high-efficient, compact pre-treatment module that carries out 5 pre-treatment functions on feedstock and can be attached easily to biogas digester feed lines.
Module disperses feedstock into small-size fractions, minimizes disruption of the bacterial environment inside the digester by deoxygenating, non-thermal hygienisation and preheating of feedstock. The combination of all these processes makes feedstock highly reactive and most favorable for the reactor microflora environment, allowing for fast & full digestion that maximizes biogas yield. WiseSoil technology competitive advantage lies in a synergy of pretreatment processes. And as a result, it simultaneously accelerates substrate digestion & increases biogas yield.
Pretreatment effect was verified for a various types of feedstock during a number laboratory tests, including tests by Bioklastr laboratory (Czech repubic), our own lab-scale biogas plant, and during pilots and installations, that are being launched on biogas plants since 2014. Some examples of the biogas production before and after processing by the pretreatment module can be found below.
Biogas production for the mixed straw - maize - manure substrate, as well as straw substrate, before and after treatment, was performed by Bioklastr Z.S. laboratory. Biogas yield improvement for these samples reached 20-23%. Full report is available on request.
Comparison of biogas yield before and after pretreatment for grain substrate. Full report is available on request.
Moreover, WiseSoil technology turns hard-to-process substrates (i.e., manure with fibrous inclusions, straw, etc.) into an available and valuable resource for biogas plant. Comparison of biogas yield for straw before and after pretreatment. Full report is available on request.
WiseSoil pretreatment module enables owners and operators of anaerobic digestion biogas plants to:
- improve digestion speed and plant throughput;
- increase biogas yield;
- use straw, slaughter waste and other energy rich substrates without additional treatment;
- decrease substrate viscosity and plant energy consumption;
- utilize smaller reactors to reduce capital costs & the footprint;
- significantly improve plant economic efficiency.
