Die Prefswässer der Riibensubstanz (z. B. die Rübenschnitzelabwässer), bisher eine Last der Fabriken, enthalten eine gewisse Menge Zucker, welcher dem Betriebe zum allergröfsten Theile verloren ging. Die Wiederbenutzung jener Wässer sowie damit die Wiedergewinnung dieses Zuckers für die Fabrikation bilden den Zweck des Verfahrens.The prefwaters of the belt substance (e.g. the Beet pulp wastewater), previously a burden for factories, contains a certain amount of sugar, which the company lost for the most part. The reuse of those Water and thus the recovery of this sugar for production form the purpose of the procedure.
Das Verfahren ist folgendes:The procedure is as follows:
Die zuckerhaltigen Ablauf- und Prefswässer gelangen in Gefäfse von entsprechenden Dimensionen, werden dort bei gewöhnlicher Temperatur mit geeigneten Mengen von Aetzkalk, anderen Aetzerdalkalien in irgend einer Form oder von Scheideschlamm versetzt, bis sich unter Umrühren der flockige Absatz deutlich und rasch von der dadurch geklärten Flüssigkeit trennt. Diese so geklärte Flüssigkeit wird entweder als solche saturirt, oder nachdem sie von . den noch darin suspendirt befindlichen organischen Substanzen in bekannter Weise befreit worden ist, wozu sich am besten das Puvrezsche Rinnenfilter (D. R. P. No. 17066) eignet.The sugary runoff and prefwaters get into vessels of appropriate dimensions, are there at ordinary temperature with suitable amounts of caustic lime, others Caustic alkalis in some form or with separating sludge added until under Stir the flaky paragraph clearly and quickly from the thereby clarified liquid separates. This so clarified liquid is either saturated as such, or after it has been . the organic substances still suspended therein are freed in a known manner has been, for which the Puvrez channel filter (D. R. P. No. 17066) is best suited.
Die Saturation kann auch gleichzeitig bei der Scheidung stattfinden. Es empfiehlt sich, die satunrte Flüssigkeit nochmals durch Puvrez'sche Rinnenfilter zu schicken. Das derartig gereinigte Abwasser wird an irgend einem Punkt in den Kreislauf der Fabrikation eingeführt, ja sogar direct auf Zucker verarbeitet.Saturation can also take place at the same time as the divorce. It is best to use the To send the saturated liquid through Puvrez's channel filter again. The one cleaned in this way Wastewater is introduced into the production cycle at some point, even Processed directly on sugar.
Der zu Anfang des Verfahrens aus den Prefswässern durch Kalk etc. abgeschiedene Rückstand (Bodensatz, Schlamm) läfst sich event, nach vorheriger Entsaftung noch, wirthschaftlich, unter anderem zu Düngerzwecken, verwerthen.The one at the beginning of the process from the prefwaters Any residue (sediment, sludge) separated by lime etc. can be after previous juicing, use it economically, including for fertilizer purposes.
