Candle Filter
Candle Filters are pressure filters that operate on a batch cycle and are used in process lines handling many chemicals and in other applications requiring efficient low-moisture cake filtration or a high degree of polishing. Candle Filters can also be used for thickening, producing a concentrated, flowable slurry through the partial removal of the liquid phase as filtrate. This mode of operation is possible because Candle Filters can operate on very short cycle times, taking advantage of high filtration rates while the filter cakes are still thin.
Components
A Candle Filter consists of three main components:
- The vessel
- The filtering elements
- The cake discharge mechanism
Batch Pressure Filtration
Candle Filters operate as pressure filters on a batch cycle, making them suitable for applications requiring efficient cake filtration or a high degree of polishing.
Thickening Operation
Candle Filters can also operate in a thickening mode to produce a concentrated, flowable slurry by partially removing the liquid phase as filtrate.
Usage
Candle Filters are used in:
Their ability to operate on very short cycle times supports high filtration rates while the cakes remain thin.
- Chemical process lines
- Applications requiring low-moisture cake filtration
- Applications requiring a high degree of polishing
- Thickening applications where a concentrated, flowable slurry is required
Candle Filters for Efficient Pressure Filtration & Thickening
Advance Expertise Technology provides Candle Filters for batch pressure filtration, low-moisture cake filtration, polishing and thickening applications.
With a configuration consisting of the vessel, filtering elements and cake discharge mechanism, Candle Filters can support process requirements involving efficient filtration as well as concentrated slurry production.
