Abstract

Disclosed is a method of reprocessing waste water containing low-molecular organic compounds such as brewery steam condensate. The process according to the invention is characterised by the fact that the waste water is led through a membrane with a molecular separation boundary which blocks organic substances with molecules below 500 Dalton in size, the permeate being re-used and the retentate disposed of.

Description

Beim Kochen der Würze in einer Brauerei werden 8-15% der Ausschlagwürze eingedampft. Dieser Dampf (Brüden) wird normalerweise über Dach weggelassen und verursacht damit starke Geruchsemissionen. Im Zuge der Emissionsminderung und Energieeinsparung wird der Brüden kondensiert und läuft dann als Abwasser in die betriebliche Kanalisation. Um eine bessere Energieausnutzung erreichen zu können, wird der Brüden in einigen Betrieben me­ chanisch verdichtet (Brüdenverdichtung) und anschließend in einem Wärmeaustauscher kon­ densiert. Die dabei abgegebene Wärme wird zum Kochen der Würze verwendet.When boiling the wort in a brewery, 8-15% of the wort is evaporated. This vapor (vapors) is usually omitted from the roof, causing it strong odor emissions. In the course of reducing emissions and saving energy, the Vapor condenses and then runs into the sewage system as wastewater. To one In some companies, the brothers will be able to achieve better energy utilization mechanically compressed (vapor compression) and then con. in a heat exchanger densifies. The heat given off is used to cook the wort.

Das Brüdenkondensat fällt mit einem konstanten Volumenstrom während des gesamten Kochvorgangs an. Es ist praktisch frei von anorganischen Komponenten (Salzen) und besitzt einen während des Kochens sich zeitlich ändernden CSB von 800-350 mg O₂/l. Die Tempera­ tur beträgt nach einem Wärmetauscher zur Restwärmenutzung 30-35°C. Damit geht neben der Wassermenge auch eine erhebliche Energiemenge ungenutzt ins Abwasser und bereitet hier vor allem wegen der hohen Temperatur Probleme.The vapor condensate falls with a constant volume flow throughout Cooking process. It is practically free of inorganic components (salts) and has a time-changing COD of 800-350 mg O₂ / l during cooking. The tempera tur is 30-35 ° C after a heat exchanger for residual heat. This goes alongside the Amount of water also wastes a considerable amount of energy into waste water and prepares it here mainly because of the high temperature problems.

Die organischen Inhaltsstoffe des Brüden werden in der Literatur mit Ester, Ketone, Terpene, Alkohole, Aldehyde, Furane, und Alkane angegeben (Brauwelt Nr. 28 (1991), S. 1212-1218; R. Meyer-Pittroff; Weihenstephan). Des weiteren wird das beim Kochvorgang entstehende DMS (Dimethylsulfid) als bedenkliche Komponente genannt. Im Kondensat, welches frei von sus­ pendierten Teilchen ist, liegen die organischen Inhaltsstoffe in gelöster Form vor.The organic ingredients of the vapors are described in the literature with esters, ketones, terpenes, Alcohols, aldehydes, furans, and alkanes are specified (Brauwelt No. 28 (1991), pp. 1212-1218; R. Meyer-Pittroff; Weihenstephan). Furthermore, the strain gage created during the cooking process (Dimethyl sulfide) mentioned as a questionable component. In the condensate, which is free of sus is suspended particles, the organic ingredients are in dissolved form.

Die organischen Komponenten im Brüdenkondensat verursachen einen sehr bitteren Ge­ schmack und einen unangenehmen Geruch. Aus diesem Grund kann das Brüdenkondensat nicht direkt im Kochprozeß wiederverwendet werden. Zur Aufbereitung muß ein Membran­ prozeß erfolgen. Dabei wird das Brüdenkondensat über eine Membran geführt. Das durch die Membran hindurchtretende Wasser ist das sogenannte Permeat; das von der Membran zu­ rückgehaltene Wasser das sogenannte Retentat oder Konzentrat.The organic components in the vapor condensate cause a very bitter Ge taste and an unpleasant smell. For this reason, the vapor condensate not be reused directly in the cooking process. A membrane must be used for processing process. The vapor condensate is passed over a membrane. That through the Water passing through the membrane is the so-called permeate; that from the membrane too retained water the so-called retentate or concentrate.

Der Rückhalt der organischen Stoffe ist vom Trennverhalten der eingesetzten Membran ab­ hängig. Nanofiltrationsmembranen halten die organischen Stoffe meistens nach dem Poren­ modell und aufgrund ihrer negativen Oberflächenladungen zurück. Die Trenngrenze der Membran wird von der Porengröße und dem Molekulargewicht der organischen Stoffe be­ stimmt. Unsere Experimente zeigen, daß mit den eingesetzten Nanofiltrationsmembranen nur CSB-Rückhalte bis 38% erreicht werden konnten.The retention of organic substances depends on the separation behavior of the membrane used pending. Nanofiltration membranes mostly keep the organic matter behind the pores model and due to its negative surface charges. The separation limit of the Membrane is based on the pore size and molecular weight of the organic substances Right. Our experiments show that with the nanofiltration membranes used only COD retention of up to 38% could be achieved.

Umkehrosmosemembranen dagegen trennen die organischen Stoffe nach dem Lösungs-Dif­ fusions-Prinzip. Der Rückhalt hängt hier für die einzelnen organischen Stoffe von der Lös­ lichkeit und der Diffusion in die Membran ab. Unsere Experimente zeigen, daß CSB-Rück­ halte von mindestens 70% erreicht werden. Mit geeigneten Umkehrosmosemembranen lassen sich die niedermolekularen Verbindungen bis auf einen kleinen Rest entfernen.In contrast, reverse osmosis membranes separate the organic substances according to the solution dif merger principle. The backing here depends on the sol for the individual organic substances and diffusion into the membrane. Our experiments show that COD re hold of at least 70% can be achieved. Leave with suitable reverse osmosis membranes the low molecular weight compounds apart from a small residue.

Da das filtrierte Brüdenkondensat praktisch salzfreies Wasser ist, kann es vorzugsweise in der Produktion (beim Einmaischen) wieder eingesetzt werden. Hier kann auch die Restwärme des Wassers optimal genutzt werden. Alternativ dazu läßt sich das zurückgewonnene Wasser auch als Vorreinigungswasser, Wasser für die Bandschmierung im Flaschenkeller oder für sonstige Reinigungszwecke verwenden.Since the filtered vapor condensate is practically salt-free water, it can preferably be in the Production (when mashing) can be used again. The residual heat of the Water can be used optimally. Alternatively, the recovered water can also as pre-cleaning water, water for belt lubrication in the bottle cellar or for other purposes Use cleaning purposes.

Analog zu Brauereien kann man auch bei anderen Produktionsprozessen (z. B. bei der Käse­ herstellung), bei denen Brüdenkondensat anfällt, verfahren.Similar to breweries, you can also use other production processes (e.g. cheese production) in which vapor condensate is produced.

Die bei der Filtration entstehende Menge Retentat - 10-20% des anfallenden Brüdenkonden­ sats - kann entweder im betriebseigenen Kraftwerk verbrannt oder in einer anaeroben Abwas­ serreinigungsanlage aufbereitet werden.The amount of retentate resulting from the filtration - 10-20% of the vapor condensate sats - can either be burned in the company's own power plant or in an anaerobic waste water water cleaning system.
