Özet

A new cake-less continuous filtration system with a spiral guide rod inserted into a ceramic tube filter and slurry prepared in a well dispersion state has been developed We tried to filter some difficult to filter materials such as iron oxide and activated sludge Especially, the algal suspension and activated sludge was not able to be filtrated by a conventional filtration system like filter press Concentrated slurries of iron oxide and activated sludge were discharged at 35 vol% and 7 55 mass% respectively The concentrates of every sample retained flowability In addition, to apply this system to a real process, we tried to calculate the filter tube number from the relationship between the filtration flux and slurry concentration As a result, the size of this system can be expected to be very compact Also, in this system, the batch operation was more effective than continuous operation
