| Beschreibung |
NAWARO Engineering GmbH, a project company of BioEnergie AG located in Leipzig, is erecting the „Klarsee“ Bioenergy Park in Penkun. All of the 40 individual digesters of the Bioenergy Park are scheduled to go onstream by fall 2007. This will make the installation the currently biggest biogas power plant worldwide having a total electric power output of 20 megawatts. The arising digestion products (approx. 408,000 t/a) are pelletized in an associated fertilizer plant to produce depot fertilizers. The liquid discharged from the fertilizer production process is treated in a vacuum evaporation unit where separation into a water and a concentrate stream takes place. The condensate arising from the evaporation process (approx. 280,000 t/a) contains large amounts of ammonium nitrogen, hardness-forming substances as well as other nutrient salts and is therefore treated in an A3 reverse osmosis plant to obtain clean water which is again fed to the biodigesters or to some extent disposed of via the discharge system. |

2006 |
| Beschreibung |
In the framework of the Piwatex projects supported by BMBF the company of A3 Water Solutions GmbH in cooperation with Wuppertal University has developed a process for the treatment of the oxidation and soap bath of the pad-steam plant. Investigation results have shown that the process is well suited for integration into the production activities. Through bath treatment the service life of the baths increases substantially. Moreover, production plant cleaning periods and downtimes are significantly brought down and energy cost for hot water generation can be saved as well. The ultrafiltration unit linked with the pad-steam plant eliminates the vat dyestuffs and COD constituents contained in the liquid so that the resulting filtrate enhances the oxidation and soap bath characteristics on a permanent basis. |
