Collaborative project: Process water treatment of distillers solubles from a bio-ethanol production of a dairy for fresh water supply - subproject 3

Project

Project code: 2815503311
Contract period: 01.10.2014 - 30.09.2017
Budget: 800,338 Euro
Purpose of research: Experimental development

The projects aim is a process for the exploitation of Wet Distillers Grains (WDG), out of the bio-ethanol production process, as a resource for freshwater supply and the additional raise of process efficiency by energy made of biogas. Therefor a new developed, designed and built rig is necessary. Sachsenmilch Leppersdorf GmbH can’t use the remains of fermentations (WDG) for a further utilization and need to dispose it in an expensive way, via thermal drying up to 25 % dry matter. For a more efficient process two main steps will be focused: A biological decrease of organic matter, contained in the substrate and an additional specific extracting of inorganic/mineral products (e. g. MAP; magnesium ammonium phosphate). The WDG treatment leads to freshwater which can be reused in dairy production. Additionally, due to the energy, made by biogas, from the anaerobic digestion, the process efficiency can be raised again. The planed work during the project will be realized by close cooperation of the three partners.Wks group GmbH is responsible for the test rigs needed components in design, scaling and build-up. Sachsenmilch Leppersdorf GmbH will resource the needed substrate (WDG) and will rate and judge the development from economical and process engineering perspectives.Fraunhofer IKTS will run the test rigs and the necessary analytical works as well as the modulation and integration of the ceramic filtration modules.
