    • Company presentationStage 1 Liquefaction:Transformation of by-products through the action of bacteria into a liquid rich in fatty acids: “acidicliquor”. Liquefaction requires a volume related to the type of inputStage 2 Methanization HYFAD:Production of methane gas by the action of methanogenic bacteria, by transforming the free fatty acidsof the liquor coming from the liquefaction tank.Optimal physico-chemical parameters are pH neutral & temperature around 38°CStage 3 post-digestion & gas storage :Post-digestion and Biogas storage Avenue Jean Monnet 1, B-1348 Louvain-La-Neuve / www.greenwatt.be / tel : +32 (0)10 77 91 00 fax :+32 (0)2 791 57 66 / info@greenwatt.be
    • Company presentationThe HYFAD is based on two tanks assembled on a metal structure before being installed on a concreteslab (Figure 1). The two tanks contain a kind of honeycomb on which the biofilm growth (Figure 2).The two tanks are connected with a set of valves that allows reaching high speeds of the liquid andproceed to the rinse of excess bacteria, therefore solving the problem of clogging (Figure 3).The system recreates, artificially and with low power consumption, the phenomenon of waves cleaningthe coast and developing an optimal thickness of the bio-filmThe advantages of HYFAD are key :1. Fully automated with low energy consumption2. No risk of clogging the fixed bed digester3. Optimal regulation of biofilm thicknessand its exchange capacity that guaranty high yieldand an extreme compacity Avenue Jean Monnet 1, B-1348 Louvain-La-Neuve / www.greenwatt.be / tel : +32 (0)10 77 91 00 fax :+32 (0)2 791 57 66 / info@greenwatt.be
    • Company presentationKey advantages of the multistage technology:1. Possibility of treating organic substrates, without the use of livestock manure, allowing for use in food industry sites2.Sturdy self-regulating process that can cope with large variations in the quantity and quality of substrate input without acidification of the digester.3. Ergonomic and compact plant with reduced running costs. Can be decentralized and placed easily on the waste production with short cycle not requesting any transport4. Optimal regulation of the pH of methanogenesis reducing the duration of the process and allowing for a quicker start-up time should the process be interrupted.5. The HYFAD methanogenesis fixed bed digester renews the biofilm avoiding all clogging problems, and guaranteeing optimal efficiency.6. Improved biogas production yield through the optimisation of each stage of the bioconversion process.7. Flexibility of use, ability to adjust the gas production depending on the supply constrains (availability of source materials) and the energy requirements.8. Optimal digestate quality – 100% traceable origins. used or sell as a high quality fertilizer Avenue Jean Monnet 1, B-1348 Louvain-La-Neuve / www.greenwatt.be / tel : +32 (0)10 77 91 00 fax :+32 (0)2 791 57 66 / info@greenwatt.be
