- DRANCO-FARM process OWS has developed the DRANCO-FARM dry digestion technology to produce renewable energy out of organic substrates such as energy crops, crop residues, agro-industrial by-products etc. The degradation of organic matter takes place under anaerobic conditions in a vertical digester. The degradable fraction is converted into biogas. The biogas can be used for the production of […]
- Feasability – Input material To assure that the input substrates will have no adverse effect on the process, several parameters need to be analyzed, providing a first impression of the suitability of a product for anaerobic digestion. Selection test In case the waste contains impurities (e.g. municipal solid waste), a thorough pre-treatment will be necessary. A selection test will […]
- Peking 2012 OWS is specialised in biological treatment of solid and semi-solid organic substrates by means of anaerobic digestion. Lorem ipsum dolor sit emeth.
- Feasability – Digestate The output after anaerobic digestion (as such or after post-treatment) can have many applications (direct use as fertilizer, compost after post-treatment, cover in landfilling,…). To evaluate what application offers the best options, it is important to analyse several parameters on the output. The selection of the necessary parameters happens in consultation with the client and […]
- DRANCO process The DRANCO (DRy ANaerobic COmposting) process is an advanced biotechnological process for an environmentally friendly and cost-effective treatment of organics derived from municipal solid waste. With its long experience and its extended reference list, the DRANCO process is a well-known and reliable anaerobic digestion technology. The DRANCO technology is marketed throughout the world by OWS […]
- SORDISEP process Wet separation technology for maximum recycling and high quality compost of MSW The wet separation process is positioned after the DRANCO digester in order to treat a digestate free from sticky organic components which are converted into biogas in the digester, facilitating wet separation and optimal removal of inerts and sand. Inerts, sand and organic […]
- Consultancy & support – Analytical assistance and biological supervision Since the biological process is the heart of the anaerobic digestion plant, a good knowledge and monitoring of this process is crucial. Analytical assistance Monitoring of substrates TS-VS, Kj-N, C/N, COD,… Biogas Production Potential Nutrient content, heavy metals … Digestion parameters TS-VS NH4+-N pH FOS, TAC VFA Viscosity … Digestate characteristics Physico-chemical (TS-VS, pH, NH4+-N,…) […]
- Consultancy & support – Electromechanical support Once the decision is made to start with anaerobic digestion, important choices have to be made regarding the necessary equipment (valves, pumps, agitators,…) and the most ideal configuration. Also in existing plants, optimization of the electromechanical equipment can lead to a more efficient process. OWS can offers assistance for both new and existing plants regarding: […]
- Household waste The introduction of anaerobic digestion into the treatment of municipal solid waste (MSW) and source separated organics (biowaste) is one of the most successful and innovative technology developments observed during the last two decades in the waste management field. Household waste organics contain energy, and Organic Waste Systems is determined to get it out!
- Introduction Anaerobic digestion, much more than biogas Anaerobic digestion is the process whereby a series of biological and enzymatic processes produce biogas out of organic material, in the absence of oxygen. The biogas consists mainly out of methane (CH4, which has a high calorific value) and CO2. Biogas is a fuel derived from organic material and is […]
