 trationen.   Eine Temperatur von 150 C   darf nicht überschritten worden, denn sonst werden die   unlöslichen   Stoffe nur zum Teil oder gar nicht zurückgehalten, da sie sich dann in einem physikalischen Zustande befinden, welcher ihnen den Durchtritt durch das Filtertuch gestattet. Man ist deshalb gezwungen, bei einer Temperatur unter   150   C die Filtration'

 darin seinen Ausdruck findet, dass die Schlammkuchen eine ganz bedeutende Dicke erreichen. Man ist aber auch gleichzeitig gezwungen, wenn man den beabsichtigten Effekt voll erreichen will, gewisse Brühenkonzentrationen einzuhalten.

   Brühen, welche in ihrer Konzentration 5 bis 60 Bé überschreiten, sind nicht mehr filtrierfähig, da nach kurzer Zeit infolge rapiden Ansteigens des Druckes die Pressung abgebrochen werden muss. Für die Filtration am geeignetsten erweisen sich Brühen, deren Konzentration zwischen   2'5   bis    3'50 Bé liegt.   Die angegebenen Bedingungen gelten für alle Arten von   Quebrachobrtihen,   mit Ausnahme jener, welche sulfitiert worden sind.

 trations. A temperature of 150 C must not be exceeded, because otherwise the insoluble substances are only partially retained or not at all, since they are then in a physical state which allows them to pass through the filter cloth. You are therefore forced to run the filtration at a temperature below 150 C
 EMI2.1
 this is expressed by the fact that the mud cakes reach a very considerable thickness. But at the same time, if you want to fully achieve the intended effect, you are forced to adhere to certain broth concentrations.

   Broths whose concentration exceeds 5 to 60 Bé can no longer be filtered, as the pressing has to be stopped after a short time due to the rapid increase in pressure. Broths with a concentration between 2'5 and 3'50 Bé have proven to be most suitable for filtration. The specified conditions apply to all types of quebracho grains, with the exception of those which have been sulfited.
